Speculation: open models is what will kill Anthropic and OpenAI. Hyperscalers can run the models without a licensing fee. Apple can make them smaller and put them on the device.
The frontier models are an edge and a liability. They're astronomically expensive to train. Without them, their models will fade into obscurity. Their marketing depends on people believing the models are meaningfully different, as people have sweatily argued on this forum. Personally, I'm not convinced there's much of a difference between these models at this point. The harness is what takes these random and hallucinogenic models and make them into something deterministic and useful.
The outcome is plausible. Open weights models though look like a tactical more than a principled play by Chinese companies to overcome the disadvantage and difficulties to access western markets. Two issues:
1. If market conditions change they might decide to close down like Meta did.
2. If as you said models keep getting more expensive to train, is an open weights strategy financially sustainable?
Open models are probably also comparatively astronomically expensive to train - just less so than the frontier models because they’re somewhat smaller, +/- the creators are more incentivised to focus on getting more from less compute because they’re have to, +/- they rely on distillation of the frontier models and this is more efficient.
But efficiencies aside; creation of open models still requires a lot of money and compute from a large organisation which is willing to accept zero return for that spend. This largesse is unlikely to continue forever; so the question is which will crack first, the frontier models’ business model or the fast followers’ generosity?
Yes, the problem with comparing open models to open source is that open source requires humans to volunteer their time. Open models requires humans to volunteer their money.
These two types of contributions have very different behavioral profiles, and it doesn't obviously follow that the historical success of getting people to collaborate socially on building software for fun and for the benefit of the community will translate in any meaningful way to the necessity of being able to raise enormous amounts of money to pay for enormous amounts of electricity.
The biggest hurdle is whether humans volunteer their expertise. Not time or money. We need top talent to make the open models. Sponsorship is plentiful. Open source volunteers are less critical with LLM doing the grunt work. Its about talent contributing to the open
Technically open source requires some amount of monetary volunteering, it's just that the electricity to run a code editor and compile (most) open source code bases is within hobby budget for most people.
I don't think it needs to be framed purely as generosity. You just need a sufficiently self-interested actor that sees open ecosystems as a necessary part of reducing their own risk profile, relative to the alternative of complete reliance of a third-party business that can take an exorbitant cut and/or Sherlock them at any time.
Valve and SteamOS are a good example of what this idea looks like in practice. (Though they may also illustrate a third thing you need: a privately-run company, that has enough profit, and enough commitment from leadership to the company's vision, that they can make long-term bets without having to eventually bow to investors seeking short-term gains.)
I’m not exactly sure on the “how” but it only makes logical sense for (non-AI) companies to band together to fund the training of a shared model. Apple is a great example, AI is not their core business but they still require it.
The only thing that took us down a different path is the vast sums of VC funding pumped into the AI companies.
The company was VC-funded as a search engine but by the time they made significant investments in AI (DeepMind etc) they'd been a publicly held company earning multiple billions a year from advertising for a decade.
Historically speaking a lot of inventions have come about without things like VC investment. Either way, there’s probably little point in debating it, just because VC funded companies control the market now doesn’t mean they should indefinitely.
How does it work if people flock to open models but they're too expensive to train? What is the financial incentive to do so?
I seem to understand open models are mostly coming from China, and the benefit of training and releasing them for 'free' is a powerful geopolitical weapon against the Western/US economy that at this point depends on OpenAI & co. to succeed.
> releasing them for 'free' is a powerful geopolitical weapon...
I agree that, currently, the Chinese govt is not only allowing but tacitly encouraging open weight model releases. However, I don't see it as an attack. I think it's more of a strategic delaying move to slow the revenue to frontier models while China works to catch up. This strategy will likely change over time.
> Will the West make open models illegal?
In the U.S. this seems highly unlikely due to the current administration's generally laissez-faire approach to tech as well as the U.S. constitution severely limiting the government's latitude to constrain economic activity.
As we saw with the temporary Mythos restriction, there are legal mechanisms to limit tech on certain grounds, but over time such limits are subject to close judicial and constitutional review. The Mythos embargo was also likely driven in part by the administration's anger at Anthropic for choosing to block the DoD from using their products for mass domestic surveillance and warfighting. I doubt we'll see any meaningful restrictions on OAI or other large companies. It'll be nearly 3 years before a different admin is in office and could enact serious limits and by then it will be too late for fundamental bans.
There are vested interests in most governments, such as intelligence agencies, law enforcement and the military, who would prefer to restrict some AI from broad use. As we saw with strong encryption, they'll only be able to delay and constrain, not stop, such a broadly useful dual-use tech. The geopolitical, economic, competitive and civil liberty interests are similar between strong encryption and AI, setting up a similar game theory dynamic. While it can be argued AI poses some potential danger, the specter of any such threat is abstract and not immediate.
On the other hand, the tech is obviously too economically essential and competitively vital to risk 'falling behind'. While there will certainly be attempts to ban, limit or constrain AI, the well-funded, highly organized commercial interests and civil libertarians will deploy lobbying, legal challenges and public opinion to ultimately prevail.
If we'd been sharing all along (as we should have been), we probably would have gotten even further along in the development of the tech.
Think of everything we could do if every researcher on the planet had first class access to the frontier. No academic fallback models. No crude API access. No limits, but direct access to the weights and the ability to lobotomize, splice, and dice.
We could pour intelligence from one container to the next without paying a tax or wearing a blindfold. All without spilling a drop.
I would definitely pay a monthly subscription to help fund a non profit compete with Anthropic and OpenAI. I already pay subscriptions for myself and 2+ other people. It's a non brainer to be able to pay for the training of better models that I can then run myself for many more. I hope someone starts this, I think this model would work. I'd start it today if I had the team and initial capital to bootstrap the infr. I know VCs won't fund it, but we definitely will, enthusiastically and continually.
My prediction is that hardware costs will make open source models impractical for the foreseeable future.
Yes, tinkerers and enthusiasts will continue to make use of them, but frontier companies will maintain near total dominance because they will be the only ones with access to the hardware.
Meta is selling their now excess compute, other compute has been on the market for a while. The current hardware cost bubble is temporary, especially once people are forced to pay the real inference price instead of majorly subsidized subscriptions.
yep, all those coders paying $200-$500 per day to use claude once subsidy ends will be seriously rethinking how much they really want to vibe-code "rewriting X in rust". Helping people write word docs, recipes, and emails isn't going to justify $15K per month subscriptions either.
Lowering the cost of hardware still won't solve the issue. HBM and DDR5 was never cheap, even before the shortages, so selling a full inference system is beyond the acceptable price range for most casual customers.
We're going to see Apple and Google compete over services and AI/OS integration instead, it will probably be years before your OEM takes local models seriously.
For the near future it seems that the new models will consume whatever improved hardware capacity we have. Competing with that is challenging, but I also think there will be strong economic incentives towards cheaper but adequate models on other providers.
I don't think we'll see home users being able to match even the low end clouds for a long time.
Longer term I think we'll see these uses of AI cluster into a few groups:
- maximal code / reasoning quality, at high prices (Fable)
- so cheap I don't care about utilization (Deepseek, and friends)
And also more niche ones:
- ultra fast with high quality answers (typically sub-SOTA). Cerebras / dedicated silicon type approaches, expensive.
- ultra fast with mostly-adequate answers, and an openness to retries, moving up to better models
I think the open models will dominate (not with individuals, but low cost providers) all except the top 1-2 of those categories, and there will be a continuous erosion on the big player's moats. The top categories are also where all the money is, but I'm not sure it can justify those investments long-term. I also think they will have to squeeze more money out of them to justify the investments, which will also drive people down the list.
I'm a bit skeptical of the token cost/ROI for all models, but sunk costs are sunk.
It has the feel of self-improving super-intelligence or bust to me.
If you get that, the frontier model(s) run away with a faster exponential.
It's a bit like semi with Moore's Law with silicon, GaAs could never catch up. If you don't get it, the fast followers crush the high investment and there's no moat. Not like they can enforce copyright!
not really a feeling; if you listen to ed zitron and strip out the vitriol, you still get the fact that the VCs are looking for some 5 trillion dollars in 5 years.
The onlly way that happens is if America turns into zimbawe.
I've driven in a LOT of the USA. Sure Chicago, NYC, DC, LA, LV... They're all built up and feel modern.
Try driving anywhere in the Midwest outside of the big cities. Dilapidated carcas buildings everywhere. Urban and rural blight. Only jobs are low paying service work. Its bleak. Like, really bad poverty as a disease bleak.
And its crazy watching it too. They're ignorant (involuntatily), poor, and trapped. And democrats only seem to care about special interest of the week, so these areas vote republican.
I don't have a solution btw. Just something I've seen growing in the last 25 years. And its getting worse, not better.
Speculation: Anthropic and and OpenAI become more like hedge funds, keeping their models to themselves, using their them and their compute for market/event prediction, internal tech development, and AI self improvement. I already wonder if that is what Google is doing. Why release your best models to help the competition? Their published models are good enough for 99% of consumers, and they can leverage their market dominance in other areas to put that consumer model in front of eyes. Then the decision to improve your internal models would both depend on whether you think they'd have value internally.
Yeah, I'm pretty sure AI is going to go insular within the largest companies. This will only be hastened by the growing national security concerns/awareness.
They would have done that long ago if it was that easy. The fact that they aren't tells us something about the actual business utility of leading models.
Completely agree. Once I can reliably get open models doing what I am on Fable ultra I imagine I will switch for good. I am fortunate to have access to a decent bit of local RAM, 192GB of DDR5 at an OK speed. It is not enough and costs are well past absurd. In a few years time I envisage a setup that is sub $10k which can accomplish such tasks. The pace so far has been breakneck. That is all I personally need. That may change, but until true AGI I do think there will be a ceiling to how much I will pay for something frontier if it is only marginally better.
This is easier to say as Fable is good (even SOTA). But people have been were saying this continuously for the current model and for now the improvement are still coming.
A better question is would you settle for o3 now or pay 20$ or 200$/month for fable ? Because o3 quality is available OSS.
It is like the new IPhone, in some sort. At some point come a feature many would like to have, despite diminishing returns.
We will see how long labs can keep up and what the scaling curve look like, but I would be more worried into losing sota status to Chinese companies than letting them take the open non-sota approach.
IMO we are there almost. I had every iphone until 14 pro and still use this today. I know what the top of the s curve feels like. From a pure model standpoint weighed against every day use cases for every day people (the right way to measure when comparing to something as ubiquitous as a phone), the models already have diminishing returns.
I think there is also the case were companies will simply use different tiers for different tasks.
While the engineering team might need a cutting edge model (with the associated costs), the marketing department will be fine by something that can grammar correct or turn a few bullet points into prose. Likewise you already don't need Fable for Ticket -> RAG -> Reply with Faq knowledge or escalate workflows
That's already the case with other very expensive software like CAD packages were oftentimes you have different feature sets enabled for different employees.
If consumers ever have enough VRAM for it locally, sure, otherwise nowhere near close.
Nvidia is looking like they are ditching consumer markets in favor of enterprise GPUs since nobodys heard a peep about the next iteration of RTX cards. The 60xx series is postponed till 2028.
Nvidias playing a dangerous gamble, in my eyes I see all the frontier labs eventually just only buying Nvidia chips for training and building custom ASICs for a fraction of the cost, longer lifespan and cheaper to host.
This will eat their 5 year gravy train for GPUs vs the 10 to 15 for ASICs.
>open models is what will kill Anthropic and OpenAI
i doubt it. it cost money to train a model. we can see that with the price increase for Kimi3. Chinese AI companies is leaving a lot of money on the table for third party providers. you think they going to let go of those money that they can make. sooner or later they will want to collect. after all, none of Chinese open weight model is release by a none profit. its all for-profit companies that is releasing open weight model.
I can't take anybody seriously when they keep declaring open models is beating frontier models. What they don't understand is that besides the huge capex to train and run inference, the real gold is in the human response to the prompt results, this is what all the Chinese companies are making their open models dirt cheap and distilling american frontier models via scraping.
The idea that we can out-parameterize frontier models is a common misconception, the true moat that Anthropic and OpenAI is why Chinese model providers are open sourcing and making it dirt cheap to keep pace through its "proxy chain operators"
The real moat aren't the models, but the tooling around the models that allow them to perform specific tasks/goals. That's what really sets apart frontier vs open. Open only has the model itself, closed have the tooling to enhance the model.
> The real moat aren't the models, but the tooling around the models that allow them to perform specific tasks/goals. That's what really sets apart frontier vs open. Open only has the model itself, closed have the tooling to enhance the model.
As these frontier companies have been boasting, writing software is now a negligible cost because the LLM can do it.
IOW, no, their software can't be a moat, because, according to their own arguments, you can use their LLM to trivially clone their software.
> you can use their LLM to trivially clone their software.
Perhaps, but what you can't clone is familiarity, polish, integration, and network effects. These companies desperately need a moat, and so for example all the new additions to Claude's web interface are becoming the products that the vast majority of people will use and be locked into (if it goes according to their plan).
unfortunately, for me, that's an anti-moat; their dark, inconcievable, alignment, random "no goblins" and inability to be reliable where their models are inevitable non-determinant means you're going to constantly run into the "this worked yesterday" problems, no matter how smart the models actually are; being filtered constantly through economics, political and ego-maniacal filters means everything you do with it will break at any given interval.
There is a massive difference when you zoom in close or take an angled perspective. You can manufacture uniqueness. The issue is when it comes to every day use for every day people there is no differentiation.
You can run the same harness on fable, opus, sonnet, and see a huge difference between them. It is true the harness is important, and openai has begun encryption its instructions to swarmed sub-agents instead of just encrypting the chain of thought, but the model is still important at this stage.
Referent of "the models are meaningfully different" reads as <top closed, top open> rather than <top closed, cheaper closed> to me, so I'm not sure why we'd be comparing Fable vs Opus/Sonnet or Sol vs Terra rather than the same against Kimi K3.
Eventually they will kill the hyperscalers too because of privacy issues. It's better for a company to pay an uprfont cost and then run everything on premise that uploading their entire codebase to a third party service.
The vast majority of companies are still putting most things in the cloud and will continue to do so and this far outnumbers the must-be-on-premise companies.
Sure there will be self-hosters but hosting AI models will always be more of a challenge than running scalable database on your own hardware and specialized hyperscalers will be here.
Would that require a watershed event to clearly establish the importance/risk of privacy though? For example, right now it seems like most big software companies w/ strong security process are comfortable uploading entire codebases to Israeli cybersecurity firms for vulnerability scanning compliance purposes
I still strongly believe Google Gemini has the best position for one simple reason: model maintenance. Accurate information is a moving target.
Open models are indeed very capable, but they will eventually become more specialized to the application to keep an edge. It makes perfect sense that the future shape of AI conforms to the landscape it was born out of.
You're saying it's important to have up-to-date facts stored in parametric knowledge? It seems to me like that's grown less and less important as agentic capabilities have grown. Even if a frontier model doesn't know something, if it's out there, it can easily find it through tool use.
The thing about not much difference between models and the harness making them deterministic and useful is wrong. Also models have different strengths and weaknesses and some are better at almost everything by a large margin compared to others.
As for your speculation, I think it's hinging on some companies releasing models for free or no big differences between models. In a world with hyperscalers and companies training models you can quickly recreate Anthropic or OpenAI by having an hyperscaler ally with a model training company, train a good/a better model, and not release it.
Open models are 4k TV (or maybe 1080p tv now and 4k TV soon) and SOTA frontier models are 8k TV. Can I or the average user tell the difference? Not really. Would they pay for that difference? Not a chance. Our entire economy is teetering on some future hope that this fragile and immaterial difference will pay off, when the reality is that LLMs are a race to the bottom and eventual razor thin margins. Maybe a tiny vocal subset of programmers can use it for work and make paying for it worth it to them, but that can't prop up an entire economy, especially when said programmers are phased out, jobless, and replaced by AI with each better iteration...
I don’t even know the names of any open source search engines, but the open source models perform decently on various benchmarks and in personal experience.
Was it ever even a claim that open source search engines were trying to outperform google, let alone kill it?
Even in the world where all models are basically equivalent (a thesis I don’t buy, but will grant you for arguments sake) - I believe there is much more to the AI business than just training and running models.
It’s a very new set of technologies, and understanding what is useful to customers and what isn’t is the whole game. Call it, product taste. There were a million cell phones before the iPhone took over the world. Why iPhone? Product taste. There are a million startups, and only a select few become unicorns. Why? Product taste.
>There were a million cell phones before the iPhone took over the world.
You have tripped yourself up there.
iPhone took over as it introduced something innovative over standard phones, but then Open Source (Android) matched the multi-touch and software differences and Apple's branding, lock-in and design etc have managed to keep it as a big player in wealthier countries. IPhone also came on the back of the massive iPod success.
ChatGPT launched the same innovation vs Google Search, but just like Android Opensource AI is moving fast now.
Android has 72.7% market share at present, Open Source AI will do the same unless the frontier labs can continue to do something new.
The frontier labs are saddled with enormous investor and other debts. How long they can keep innovating by spending so much on R&D and paying there staff very high wages remains to be seen.
Once investors cash out via an IPO, the companies are back down to earth and playing in the real world again.
Android has market share, but Apple makes all of the money! I find it really funny when people attribute Apple’s success to “oh, the only reason they succeed is design and marketing.” Yeah, I mean factually speaking design and marketing actually do matter a lot!
Us developer types like to pretend like specs are the only thing that matters? If you could have a 10x more powerful model you could only access running locally through your terminal, versus a weaker model through a clean web interface, normies will pick the web ui every single time. Product experience is simply everything, as much as we like to pretend like nitty technical decisions are the most important thing.
> Android has market share, but Apple makes all of the money!
So? The benefit of open source is that you don’t have to worry about making a ton of money. You just need to be viable.
Apple: premium product a minority is willing to pay for
Android: standard product the majority use
I’m sure there will continue to be iPhone equivalents in the AI world, premium bespoke models. But the vast majority of people will be happy with a cheaper offering.
Well I think a critical difference is that, unlike Apple, OpenAI and Anthropic have taken on so much VC funding that a 20-something % market share is not going to be enough for them. So open models could kill them, not because of the techonology but because of the way they're financed.
> If you could have a 10x more powerful model you could only access running locally through your terminal, versus a weaker model through a clean web interface, normies will pick the web ui every single time.
More like if you could have a 1.25x more powerful model that you could only access through some weird surveillance megacorps aggressive monetization scheme, or choose from 100 others running open models and accessible through 100 different interfaces pandering to every taste.
Normies will choose the megacorp every time, because that was the one in the tv commercial, and within six months will have left for one of the others in a rage.
The only corporate hope is that the government steps in to ban their competition.
While that may be technically true for a strict definition of “smartphone,” there’s no denying the iPhone redefined the concept in a way that its competitors were forced to copy to have any hope of keeping up. Nobody hears the word “smartphone” and thinks of a Blueberry or Treo anymore.
That's a subjective question, so I'll give a subjective answer. The browser, for better or worse, was a lot less dumbed down for mobile than competitors, the stylus-less touch interface reduced UI friction and the odds that you'd lose a critical (if inexpensive) component, and the slew of contemporary iPod users could easily migrate their libraries over.
Exactly 4 months ago, the marketshare on openrouter was 60%-40% in favor of closed models. Now it's 63%-37% in favor of open models. On March 19th, the open models processed 888B tokens in aggregate, yesterday, they processed 4.19T tokens in aggregate. That's almost 5x in 4 months! I can't think of the right intensifier to describe this level of growth.
If you are looking for more details (as inferred by openrouter data), I built a dashboard that updates daily: https://dirac.run/labs-market-share
This right here is going to be considered one of the first major signs of the downfall of closed models years from now.
And look, if you disagree with me PLEASE tell me why. What moat do these companies have? I genuinely want to know because looking at the spend for companies like OAI and Anthropic with no actual moat I can identify is actually driving me insane.
I think the frontier AI companies think you're missing key details:
- they can still discover entire new untapped markets for AI (that, potentially, only their models can unlock)
- they can find (novel, unique to them) ways to drive down the cost of running their models
- they can provide other ancillary value (e.g. write better harnesses) because of their expertise, and then charge for that value
I'm probably missing a few bullet points also. However, none of those are moats (or at least not yet) ... I'd consider them more like bets. The frontier AI companies are betting "the house" on them, and if they pay off they could, hypothetically, make them financially competitive.
I've been keeping my cash/stock ratio a bit higher than usual recently because I'm waiting for the bubble to burst. My "stock" side is mostly a company I work for that is riding the wave.
If we use the same logic as the AI boosters and just assume we're in exponential growth, that means in a year open models will be handling 523T tokens.
> Mozilla exists because one company tried to own the front door to the web, and an open community rose up to make sure it never could.
I'd say that the front door to the web is pretty much owned by Google and Apple at this point given Firefox current marketshare. And maybe that's enough, maybe a future where a low percentage of open models keep the rest of the system honest but that doesn't seem the argument of this article
Mozilla exists because one company owned the front door to the web, and another company abused their market position to push their free (as in beer) browser. Mozilla is the phoenix rising from the ashes of that first company.
Then another company came along, abused their market position to push their free browser, demolished Firefox's market share but keep handing them cash to avoid the appearance of a monopoly
As someone that's generally for the proliferation of open models, I want to take this seriously, but it's really difficult when it was clearly written by AI.
I guess they fired whoever used to write copy for these things.
Edit: to be clear, I'm not trying to just dunk on them, I think it's actively hurting their own point to do this, and counter-productive when people can easily clock it - it makes some percent of the audience immediately tune out.
It sure is nice to see that Mozilla is still doing all that they can to keep on top of current trends, except developing a decent privacy-focused web browser for developers and power users.
Yes, Firefox itself is a “general purpose” browser, and that’s probably for the best in terms of wide market appeal. Other developers have taken the engine and made power-user-focused browsers with it. Lately I’ve fallen in love with Zen (though after 2 months of use its pinned tabs features still confuse me a bit).
I’m not ready to celebrate the victory of open models just yet considering all the good ones are built by private, VC funded companies. How long will they continue to be charitable? And what’s their actual business model once the money stops and investors start demanding returns?
The design and layout made it harder to read than it needed to be.
Regardless, the inference costs dropping almost 50× is really amazing to see. And now Kimi K3 release has shown how open models are getting closer to the frontier level already. Open source AI is moving a lot faster than Anthropic and OpenAI would have expected lol.
Gemini had a pop-up on my phone today, asking me if I wanted to "bring Gemini up to speed" by importing conversations from my other AI apps. This tells me that Google is threatened, or data hungry as always, or both. Open source AI, Anthropic, and OpenAI, knocking on doors.
mozilla only began babbling about open source ai when they got their teeth extracted for free via the entire community giving them the curbiest of curbstomps.
i still use firefox but hot damn did they utterly fail to read the room initially. the only other company i can think of in recent memory -- besides sony cutting out discs -- is logitech when their ceo began gibbering about a subscription mouse or microsoft and its copilot button(s).
The issue is that all of the text is a quote, and that renders enormous. That’s probably fine for a tiny quote amongst more text, but here it is jarring.
querySelector/querySelectorAll() are great for plucking out deeply nested elements but if all you need is to find all elements of a certain class and the API gives you a tool to do exactly that, why not do that instead of reaching for the general-purpose Swiss army knife? Sure, the execution speed difference may be only measurable in microseconds, but it takes about the same amount of time to type so why not use the specific tool?
It's their own fonts: Mozilla Headline and Mozilla Text.
No idea why they'd be using the display font for the abstract though, that kind of defeats the whole purpose. It's supposed to be quirky and bold, but used far more sparsingly.
It appears open models were used to create this slop.
That opening is so hard to understand what they are trying to say, from the font and how it's written. It took me several times rereading to even grasp.
Plus the article is filled with cryptic things like:
Open ships easy.
Open deploys hard.
What?! Is it a meta answer to "the state of open source AI" question?
I think it’s supposed to mean “open source is easily shipped, but open source is hard to deploy”? Or perhaps “deploys hard” is a figure of speach, as in “we are deploying this open source and we are deploying it /hard/“? I don’t know, it’s not good.
This is truly some proper slop. The "PRODUCTION RATE BY COMPANY SIZE" graph has bars that start offset from the text underneath them, which LOOKS like a mistake that happened due to word wrap, but if you visibly compare the 54% to the 55% bars they seem to have compensated for this?! I can't tell if his was on purpose or accident and it's impossible to take the data seriously!
This is on mobile in portrait. In landscape the text doesn't wrap or offset anything.
This new trend of content appearing while scrolling down is so terrible accessibility-wise, I do not understand how Mozilla of all institutions would do it.
Not every trend needs to be followed. Have some backbone. You receive donations to have that.
___
Apart from the website being - frankly - bullshit, the content is also - frankly - bullshit.
It's just on the frontpage because the title says "open source AI".
> This new trend of content appearing while scrolling down is so terrible accessibility-wise, I do not understand how Mozilla of all institutions would do it.
Could you explain what is wrong with the accessibility of this page? All the content is included in the html payload, so it is accessible to screen readers and text-based browsers; and as for the "reveal" effect, it seems to respect user's choice of "prefers reduced motion" and is disabled when that is user's preference.
> it seems to respect user's choice of "prefers reduced motion".
Cool, that I didn't check, because it is impossible to enable that setting, as it breaks _huge_ amounts of websites.
I'm not aware of a way to enable it selectively, but one could also just display the content at all times. It's a static page. It's static content. None of this makes any sense.
___
The idea behind that style of gradual reveal is probably some kind of storytelling, but the only story it tells is that mozilla is wasting donations on people with incorrect opinions that could be used on.. idk not building torment nexii?
Seems quite odd to use OpenRouter as “proof” that open weights models won. If you’re using OpenRouter, you’re already looking to bypass frontier models. To suggest there’s no longer a tradeoff simply isn’t true. But this isn’t the first time I thought Mozilla was a less than trustworthy source of information.
I think "If you’re using OpenRouter, you’re already looking to bypass frontier models." is false. Our company uses both Claude subscriptions and OpenRouter ... and a lot of what we use OpenRouter for is more Claude.
We do a little exploration with other models through it, but it's not at all accurate to say we use it because we are "already looking to bypass frontier models".
There isn't any open-source AI. There is Open AI (not to be confused with the closed company called OpenAI, which was unable to trademark its name). There's no open source AI both because the open source community doesn't have the resources to train a useful AI and because AI doesn't have source code.
I don't know of any useful model that would match the usual definition of "open source". That is, where everything needed to build the thing is provided, such as the training data and code. Not that it would be tremendously useful anyways considering how expensive training a model is.
I much prefer the "open weights" term. It is not open source in the sense that you only get the finished product, not the actual source, but it is still open in the sense that it is not only accessible as a service.
For an analogy, take Quake for instance. When it was launched, its game server was available as an executable, so you could run it your machine, but that didn't make it open source. Only much later it was released as true open source software.
The UI is really hard on the eyes. Personally, I think the font size is way too big, and the animation timing feels off. If this is a benchmark page and not a product page, I feel like the information should be scannable at a glance. The UX is bad.
I'm unsure what it is about AI developers seemingly not having eyeballs. The Hermes Agent website is absolutely eye-searing and the application itself resembles some sort of weird "RETVRN" greek-styled travel agent website.
I think Mozilla is chasing a past formula, but the projection isn't linear enough to remain consistent, and the critical parts of the outcome, utter centralization of the market dominance of the three C's, are left out of the equation.
We might get the consolation prize, a few nerds having competitive alternatives to applaud, but we will be left with the hidden costs: stagnation by bloated market leaders, consumers and businesses pouring trillions of dollars into the commercial offerings while open development wonders where money comes from, and the leakage of these imbalances into political and social spheres.
If we follow a Mozilla template and get to the peak of Mozilla's success at the web, look at what that really is. Facebook, Amazon, Google etc are orthogonal to that equation.
I think the fact that Mozilla survival model ultimately depends on Google's money means Google is keeping a corpse propped up just to have a defense argument that a browser competitor still exists, so they don't get hit with monopoly regulations.
Haven't been following the articles and snippets we get from these labs about training their models for a while. But I'm guessing the latest chinese models are way less based on distilling? If not, then your speed of progress is still limited by the two labs (which we are collectively, in various forms subsidizing).
There's nothing practical about open-source models yet that makes them even remotely comparable to closed frontier models.
All the hype around GLM, Qwen, now Kimi.... Are people really this naive that they believe these reports or, more worringly, are people NOT using these models and seeing the HUGE gap that still exists?
Take a task, any medium-sized task, decently scoped that you'd trust to give to Sonnet to finish without a hitch. Now give it to ANY open-source frontier model and watch them struggle and go in circles while failing tool calls and randomly assuming things.
Open-source is and has been amazing but its so hard to deploy reliably and at scale and there's still big problems in the underlying models with instruction following and tool calling that makes it basically unusable for production workloads at a decent price point...

Claude used to be much worse than it is now, just as bad the open weights models are. And the open weights were worse. The labs will also try to keep the lead, but at some point people start seeing real value from open models. Maybe you say they're not ready yet for medium tasks, but everyone sees the writing on the wall.
I hope you're right and I want you to be right, but, even seeing the current hype around local models, etc... and open-source models, I think the industry is currently under a big confusion where they see the benchmarks of things like Kimi, GLM, Qwen, they play with it via opencode, and they think like: "Wow this is pretty good, I want to deploy this". But they don't understand how the KV cache grows over time and can take almost as much memory as needed for a 30B param model, they dont understand that a quantized model WILL NOT be the same as a full precision one, and they surely don't see the engineering work needed to serve inference to even tens of customers at a decent quality and latency level.
The biggest moat of these giant labs and models is increasingly shifting towards deployment capabilities and (debatably) having better (proprietary) harnesses.
The models themselves can be impressive on benchmarks, but unless they can be served reliably to customers either at scale, hosted somewhere, or even on edge with predictable latency and memory usage, then frontier will always be leading.
It sounds like you're focusing on the problems of running local models, or running models yourself, but I don't think that many people seriously expect near term improvement on that, it's definitely more just hopeful thinking there. That's not what I meant to address, and I also am in more of a "wait and see" mode.
But at this point we do expect that open weights _hosted_ options become feasible for the tasks they're using the frontier models for. And because of the lack of "legal monopoly" (intellectual property of whatever kind), they're way cheaper, not mention more flexible.
The launch of the tinker platform from Thinking Machines is an example of the "more flexibility" part that people want (and they chose to make their model open weights, maybe because this is the angle they want to push).
At this point I think it's realistic enough that the ball is in OpenAI / Anthropic's court to figure out how to respond to this threat to their business model.
That said, I think it's concerning that there are apparently only a couple of providers of hosted open weights inference, due to the complexities of doing so (per Dax from OpenCode's tweets).
Speculation: open models is what will kill Anthropic and OpenAI. Hyperscalers can run the models without a licensing fee. Apple can make them smaller and put them on the device.
The frontier models are an edge and a liability. They're astronomically expensive to train. Without them, their models will fade into obscurity. Their marketing depends on people believing the models are meaningfully different, as people have sweatily argued on this forum. Personally, I'm not convinced there's much of a difference between these models at this point. The harness is what takes these random and hallucinogenic models and make them into something deterministic and useful.
The outcome is plausible. Open weights models though look like a tactical more than a principled play by Chinese companies to overcome the disadvantage and difficulties to access western markets. Two issues:
1. If market conditions change they might decide to close down like Meta did.
2. If as you said models keep getting more expensive to train, is an open weights strategy financially sustainable?
edit: typo
Open models are probably also comparatively astronomically expensive to train - just less so than the frontier models because they’re somewhat smaller, +/- the creators are more incentivised to focus on getting more from less compute because they’re have to, +/- they rely on distillation of the frontier models and this is more efficient.
But efficiencies aside; creation of open models still requires a lot of money and compute from a large organisation which is willing to accept zero return for that spend. This largesse is unlikely to continue forever; so the question is which will crack first, the frontier models’ business model or the fast followers’ generosity?
Yes, the problem with comparing open models to open source is that open source requires humans to volunteer their time. Open models requires humans to volunteer their money.
These two types of contributions have very different behavioral profiles, and it doesn't obviously follow that the historical success of getting people to collaborate socially on building software for fun and for the benefit of the community will translate in any meaningful way to the necessity of being able to raise enormous amounts of money to pay for enormous amounts of electricity.
The biggest hurdle is whether humans volunteer their expertise. Not time or money. We need top talent to make the open models. Sponsorship is plentiful. Open source volunteers are less critical with LLM doing the grunt work. Its about talent contributing to the open
Technically open source requires some amount of monetary volunteering, it's just that the electricity to run a code editor and compile (most) open source code bases is within hobby budget for most people.
I don't think it needs to be framed purely as generosity. You just need a sufficiently self-interested actor that sees open ecosystems as a necessary part of reducing their own risk profile, relative to the alternative of complete reliance of a third-party business that can take an exorbitant cut and/or Sherlock them at any time.
Valve and SteamOS are a good example of what this idea looks like in practice. (Though they may also illustrate a third thing you need: a privately-run company, that has enough profit, and enough commitment from leadership to the company's vision, that they can make long-term bets without having to eventually bow to investors seeking short-term gains.)
I’m not exactly sure on the “how” but it only makes logical sense for (non-AI) companies to band together to fund the training of a shared model. Apple is a great example, AI is not their core business but they still require it.
The only thing that took us down a different path is the vast sums of VC funding pumped into the AI companies.
If not for VC-funded LLMs there wouldn't be any LLMs.
Most of the innovations needed for LLMs came from people at Google.
> came from people at Google
Who had to leave to build anything.
So VC-funded.
The company was VC-funded as a search engine but by the time they made significant investments in AI (DeepMind etc) they'd been a publicly held company earning multiple billions a year from advertising for a decade.
Google is a VC. Their side projects are VC projects.
[citation needed]
Historically speaking a lot of inventions have come about without things like VC investment. Either way, there’s probably little point in debating it, just because VC funded companies control the market now doesn’t mean they should indefinitely.
How does it work if people flock to open models but they're too expensive to train? What is the financial incentive to do so?
I seem to understand open models are mostly coming from China, and the benefit of training and releasing them for 'free' is a powerful geopolitical weapon against the Western/US economy that at this point depends on OpenAI & co. to succeed.
Will the West make open models illegal?
> releasing them for 'free' is a powerful geopolitical weapon...
I agree that, currently, the Chinese govt is not only allowing but tacitly encouraging open weight model releases. However, I don't see it as an attack. I think it's more of a strategic delaying move to slow the revenue to frontier models while China works to catch up. This strategy will likely change over time.
> Will the West make open models illegal?
In the U.S. this seems highly unlikely due to the current administration's generally laissez-faire approach to tech as well as the U.S. constitution severely limiting the government's latitude to constrain economic activity.
As we saw with the temporary Mythos restriction, there are legal mechanisms to limit tech on certain grounds, but over time such limits are subject to close judicial and constitutional review. The Mythos embargo was also likely driven in part by the administration's anger at Anthropic for choosing to block the DoD from using their products for mass domestic surveillance and warfighting. I doubt we'll see any meaningful restrictions on OAI or other large companies. It'll be nearly 3 years before a different admin is in office and could enact serious limits and by then it will be too late for fundamental bans.
There are vested interests in most governments, such as intelligence agencies, law enforcement and the military, who would prefer to restrict some AI from broad use. As we saw with strong encryption, they'll only be able to delay and constrain, not stop, such a broadly useful dual-use tech. The geopolitical, economic, competitive and civil liberty interests are similar between strong encryption and AI, setting up a similar game theory dynamic. While it can be argued AI poses some potential danger, the specter of any such threat is abstract and not immediate.
On the other hand, the tech is obviously too economically essential and competitively vital to risk 'falling behind'. While there will certainly be attempts to ban, limit or constrain AI, the well-funded, highly organized commercial interests and civil libertarians will deploy lobbying, legal challenges and public opinion to ultimately prevail.
If by West you mean the USA, maybe.
Other countries in the westen hemisphere, probably not.
> Will the West make open models illegal?
We better not.
> What is the financial incentive to do so?
If we'd been sharing all along (as we should have been), we probably would have gotten even further along in the development of the tech.
Think of everything we could do if every researcher on the planet had first class access to the frontier. No academic fallback models. No crude API access. No limits, but direct access to the weights and the ability to lobotomize, splice, and dice.
We could pour intelligence from one container to the next without paying a tax or wearing a blindfold. All without spilling a drop.
*Open* *Must* *Win*
> No X. No Y. No Z, but Q
"You wouldn't download an LLM"
You wouldn't crash the stock market by preferring Chinese models.
I would definitely pay a monthly subscription to help fund a non profit compete with Anthropic and OpenAI. I already pay subscriptions for myself and 2+ other people. It's a non brainer to be able to pay for the training of better models that I can then run myself for many more. I hope someone starts this, I think this model would work. I'd start it today if I had the team and initial capital to bootstrap the infr. I know VCs won't fund it, but we definitely will, enthusiastically and continually.
My prediction is that hardware costs will make open source models impractical for the foreseeable future.
Yes, tinkerers and enthusiasts will continue to make use of them, but frontier companies will maintain near total dominance because they will be the only ones with access to the hardware.
Meta is selling their now excess compute, other compute has been on the market for a while. The current hardware cost bubble is temporary, especially once people are forced to pay the real inference price instead of majorly subsidized subscriptions.
yep, all those coders paying $200-$500 per day to use claude once subsidy ends will be seriously rethinking how much they really want to vibe-code "rewriting X in rust". Helping people write word docs, recipes, and emails isn't going to justify $15K per month subscriptions either.
Lowering the cost of hardware still won't solve the issue. HBM and DDR5 was never cheap, even before the shortages, so selling a full inference system is beyond the acceptable price range for most casual customers.
We're going to see Apple and Google compete over services and AI/OS integration instead, it will probably be years before your OEM takes local models seriously.
Apple and Google (via smartphones) are in literally everyone's pocket.
Running KIMI on a phone is not possible today and I agree with you that it will "probably be years before..." it is.
But how many years do you guess? I personally do not think it will take even 10 years for the situation to be commonplace.
For the near future it seems that the new models will consume whatever improved hardware capacity we have. Competing with that is challenging, but I also think there will be strong economic incentives towards cheaper but adequate models on other providers.
I don't think we'll see home users being able to match even the low end clouds for a long time.
Longer term I think we'll see these uses of AI cluster into a few groups:
- maximal code / reasoning quality, at high prices (Fable)
- typical code / agents (sub-Opus, Terra)
- cheap but decent enough quality (think Deepseek / GLM / Luna)
- so cheap I don't care about utilization (Deepseek, and friends)
And also more niche ones:
- ultra fast with high quality answers (typically sub-SOTA). Cerebras / dedicated silicon type approaches, expensive.
- ultra fast with mostly-adequate answers, and an openness to retries, moving up to better models
I think the open models will dominate (not with individuals, but low cost providers) all except the top 1-2 of those categories, and there will be a continuous erosion on the big player's moats. The top categories are also where all the money is, but I'm not sure it can justify those investments long-term. I also think they will have to squeeze more money out of them to justify the investments, which will also drive people down the list.
Edit: clarifications.
There will be plenty of model providers with prices that undercut Anthropic/OpenAI's prices.
Doubtful for the same reasons. The frontier providers are working at a hardware scale that will make it impractical to undercut them.
I wouldn't rule out the possibility completely, but it won't be very common.
I'm a bit skeptical of the token cost/ROI for all models, but sunk costs are sunk.
It has the feel of self-improving super-intelligence or bust to me. If you get that, the frontier model(s) run away with a faster exponential. It's a bit like semi with Moore's Law with silicon, GaAs could never catch up. If you don't get it, the fast followers crush the high investment and there's no moat. Not like they can enforce copyright!
not really a feeling; if you listen to ed zitron and strip out the vitriol, you still get the fact that the VCs are looking for some 5 trillion dollars in 5 years.
The onlly way that happens is if America turns into zimbawe.
Who says it hasn't already?
I've driven in a LOT of the USA. Sure Chicago, NYC, DC, LA, LV... They're all built up and feel modern.
Try driving anywhere in the Midwest outside of the big cities. Dilapidated carcas buildings everywhere. Urban and rural blight. Only jobs are low paying service work. Its bleak. Like, really bad poverty as a disease bleak.
And its crazy watching it too. They're ignorant (involuntatily), poor, and trapped. And democrats only seem to care about special interest of the week, so these areas vote republican.
I don't have a solution btw. Just something I've seen growing in the last 25 years. And its getting worse, not better.
>Who says it hasn't already?
Great.
Speculation: Anthropic and and OpenAI become more like hedge funds, keeping their models to themselves, using their them and their compute for market/event prediction, internal tech development, and AI self improvement. I already wonder if that is what Google is doing. Why release your best models to help the competition? Their published models are good enough for 99% of consumers, and they can leverage their market dominance in other areas to put that consumer model in front of eyes. Then the decision to improve your internal models would both depend on whether you think they'd have value internally.
Yeah, I'm pretty sure AI is going to go insular within the largest companies. This will only be hastened by the growing national security concerns/awareness.
They would have done that long ago if it was that easy. The fact that they aren't tells us something about the actual business utility of leading models.
Completely agree. Once I can reliably get open models doing what I am on Fable ultra I imagine I will switch for good. I am fortunate to have access to a decent bit of local RAM, 192GB of DDR5 at an OK speed. It is not enough and costs are well past absurd. In a few years time I envisage a setup that is sub $10k which can accomplish such tasks. The pace so far has been breakneck. That is all I personally need. That may change, but until true AGI I do think there will be a ceiling to how much I will pay for something frontier if it is only marginally better.
This is easier to say as Fable is good (even SOTA). But people have been were saying this continuously for the current model and for now the improvement are still coming.
A better question is would you settle for o3 now or pay 20$ or 200$/month for fable ? Because o3 quality is available OSS.
It is like the new IPhone, in some sort. At some point come a feature many would like to have, despite diminishing returns.
We will see how long labs can keep up and what the scaling curve look like, but I would be more worried into losing sota status to Chinese companies than letting them take the open non-sota approach.
IMO we are there almost. I had every iphone until 14 pro and still use this today. I know what the top of the s curve feels like. From a pure model standpoint weighed against every day use cases for every day people (the right way to measure when comparing to something as ubiquitous as a phone), the models already have diminishing returns.
I think there is also the case were companies will simply use different tiers for different tasks.
While the engineering team might need a cutting edge model (with the associated costs), the marketing department will be fine by something that can grammar correct or turn a few bullet points into prose. Likewise you already don't need Fable for Ticket -> RAG -> Reply with Faq knowledge or escalate workflows
That's already the case with other very expensive software like CAD packages were oftentimes you have different feature sets enabled for different employees.
"that can grammar correct" ... Did you do that on purpose?
If consumers ever have enough VRAM for it locally, sure, otherwise nowhere near close.
Nvidia is looking like they are ditching consumer markets in favor of enterprise GPUs since nobodys heard a peep about the next iteration of RTX cards. The 60xx series is postponed till 2028.
Nvidias playing a dangerous gamble, in my eyes I see all the frontier labs eventually just only buying Nvidia chips for training and building custom ASICs for a fraction of the cost, longer lifespan and cheaper to host.
This will eat their 5 year gravy train for GPUs vs the 10 to 15 for ASICs.
>open models is what will kill Anthropic and OpenAI
i doubt it. it cost money to train a model. we can see that with the price increase for Kimi3. Chinese AI companies is leaving a lot of money on the table for third party providers. you think they going to let go of those money that they can make. sooner or later they will want to collect. after all, none of Chinese open weight model is release by a none profit. its all for-profit companies that is releasing open weight model.
I can't take anybody seriously when they keep declaring open models is beating frontier models. What they don't understand is that besides the huge capex to train and run inference, the real gold is in the human response to the prompt results, this is what all the Chinese companies are making their open models dirt cheap and distilling american frontier models via scraping.
The idea that we can out-parameterize frontier models is a common misconception, the true moat that Anthropic and OpenAI is why Chinese model providers are open sourcing and making it dirt cheap to keep pace through its "proxy chain operators"
https://x.com/HarshalsinghCN/status/2056626175959826692
The real moat aren't the models, but the tooling around the models that allow them to perform specific tasks/goals. That's what really sets apart frontier vs open. Open only has the model itself, closed have the tooling to enhance the model.
> The real moat aren't the models, but the tooling around the models that allow them to perform specific tasks/goals. That's what really sets apart frontier vs open. Open only has the model itself, closed have the tooling to enhance the model.
As these frontier companies have been boasting, writing software is now a negligible cost because the LLM can do it.
IOW, no, their software can't be a moat, because, according to their own arguments, you can use their LLM to trivially clone their software.
> you can use their LLM to trivially clone their software.
Perhaps, but what you can't clone is familiarity, polish, integration, and network effects. These companies desperately need a moat, and so for example all the new additions to Claude's web interface are becoming the products that the vast majority of people will use and be locked into (if it goes according to their plan).
unfortunately, for me, that's an anti-moat; their dark, inconcievable, alignment, random "no goblins" and inability to be reliable where their models are inevitable non-determinant means you're going to constantly run into the "this worked yesterday" problems, no matter how smart the models actually are; being filtered constantly through economics, political and ego-maniacal filters means everything you do with it will break at any given interval.
good luck.
There is a massive difference when you zoom in close or take an angled perspective. You can manufacture uniqueness. The issue is when it comes to every day use for every day people there is no differentiation.
> Apple can make them smaller and put them on the device
Someone can, but Apple has essentially admitted defeat and handed the reigns over to Google.
Have they?
https://www.cnbc.com/amp/2026/07/14/apple-prismml-ai-compres...
> handed the reigns over
Oh man, they gave them free reign?
How will anyone reign them in now?
For all intensive porpoises, this is like Babe Ruth, chomping at the bat!
You can run the same harness on fable, opus, sonnet, and see a huge difference between them. It is true the harness is important, and openai has begun encryption its instructions to swarmed sub-agents instead of just encrypting the chain of thought, but the model is still important at this stage.
This will only delay the inevitable. Sitting on some magic prompts is hardly the moat they need.
Referent of "the models are meaningfully different" reads as <top closed, top open> rather than <top closed, cheaper closed> to me, so I'm not sure why we'd be comparing Fable vs Opus/Sonnet or Sol vs Terra rather than the same against Kimi K3.
Haven't tried Kimi K3 for now but there was a huge difference between GPT 5.6/Fable and GLM 5.2/Kimi K2.7 that were previous frontier open models.
Eventually they will kill the hyperscalers too because of privacy issues. It's better for a company to pay an uprfont cost and then run everything on premise that uploading their entire codebase to a third party service.
The vast majority of companies are still putting most things in the cloud and will continue to do so and this far outnumbers the must-be-on-premise companies.
Sure there will be self-hosters but hosting AI models will always be more of a challenge than running scalable database on your own hardware and specialized hyperscalers will be here.
Would that require a watershed event to clearly establish the importance/risk of privacy though? For example, right now it seems like most big software companies w/ strong security process are comfortable uploading entire codebases to Israeli cybersecurity firms for vulnerability scanning compliance purposes
> Their marketing depends on people believing the models are meaningfully different, as people have sweatily argued on this forum.
They are noticeably different. Benchmarks, anecdotes, all say the same thing.
Now, is a ~6 month lead actually worth 1 gajillion dollars? Maybe not.
I still strongly believe Google Gemini has the best position for one simple reason: model maintenance. Accurate information is a moving target.
Open models are indeed very capable, but they will eventually become more specialized to the application to keep an edge. It makes perfect sense that the future shape of AI conforms to the landscape it was born out of.
You're saying it's important to have up-to-date facts stored in parametric knowledge? It seems to me like that's grown less and less important as agentic capabilities have grown. Even if a frontier model doesn't know something, if it's out there, it can easily find it through tool use.
Grok has the biggest advantage in current events knowledge because it's integrated with X, which enough people still use even though it isn't Twitter.
Hm, when compared to all the information people with android devices share with google, or those with gmail, ..
The thing about not much difference between models and the harness making them deterministic and useful is wrong. Also models have different strengths and weaknesses and some are better at almost everything by a large margin compared to others.
As for your speculation, I think it's hinging on some companies releasing models for free or no big differences between models. In a world with hyperscalers and companies training models you can quickly recreate Anthropic or OpenAI by having an hyperscaler ally with a model training company, train a good/a better model, and not release it.
Open models are 4k TV (or maybe 1080p tv now and 4k TV soon) and SOTA frontier models are 8k TV. Can I or the average user tell the difference? Not really. Would they pay for that difference? Not a chance. Our entire economy is teetering on some future hope that this fragile and immaterial difference will pay off, when the reality is that LLMs are a race to the bottom and eventual razor thin margins. Maybe a tiny vocal subset of programmers can use it for work and make paying for it worth it to them, but that can't prop up an entire economy, especially when said programmers are phased out, jobless, and replaced by AI with each better iteration...
Just like opensource search engines killed google
oh wait
I don’t even know the names of any open source search engines, but the open source models perform decently on various benchmarks and in personal experience.
Was it ever even a claim that open source search engines were trying to outperform google, let alone kill it?
Yacy tried in the 2000s. I'm sure some magazines made headlines posing the question whether yacy is a google-killer
Marginalia already gives me better results for many queries than Google. Because Google has sunk so low.
Even in the world where all models are basically equivalent (a thesis I don’t buy, but will grant you for arguments sake) - I believe there is much more to the AI business than just training and running models.
It’s a very new set of technologies, and understanding what is useful to customers and what isn’t is the whole game. Call it, product taste. There were a million cell phones before the iPhone took over the world. Why iPhone? Product taste. There are a million startups, and only a select few become unicorns. Why? Product taste.
>There were a million cell phones before the iPhone took over the world.
You have tripped yourself up there.
iPhone took over as it introduced something innovative over standard phones, but then Open Source (Android) matched the multi-touch and software differences and Apple's branding, lock-in and design etc have managed to keep it as a big player in wealthier countries. IPhone also came on the back of the massive iPod success.
ChatGPT launched the same innovation vs Google Search, but just like Android Opensource AI is moving fast now.
Android has 72.7% market share at present, Open Source AI will do the same unless the frontier labs can continue to do something new.
The frontier labs are saddled with enormous investor and other debts. How long they can keep innovating by spending so much on R&D and paying there staff very high wages remains to be seen.
Once investors cash out via an IPO, the companies are back down to earth and playing in the real world again.
Android has market share, but Apple makes all of the money! I find it really funny when people attribute Apple’s success to “oh, the only reason they succeed is design and marketing.” Yeah, I mean factually speaking design and marketing actually do matter a lot!
Us developer types like to pretend like specs are the only thing that matters? If you could have a 10x more powerful model you could only access running locally through your terminal, versus a weaker model through a clean web interface, normies will pick the web ui every single time. Product experience is simply everything, as much as we like to pretend like nitty technical decisions are the most important thing.
> Android has market share, but Apple makes all of the money!
So? The benefit of open source is that you don’t have to worry about making a ton of money. You just need to be viable.
Apple: premium product a minority is willing to pay for
Android: standard product the majority use
I’m sure there will continue to be iPhone equivalents in the AI world, premium bespoke models. But the vast majority of people will be happy with a cheaper offering.
The original comment was “open models are what kill OpenAI and Anthropic”, which to me is as silly as saying “Android is what killed Apple”
Well I think a critical difference is that, unlike Apple, OpenAI and Anthropic have taken on so much VC funding that a 20-something % market share is not going to be enough for them. So open models could kill them, not because of the techonology but because of the way they're financed.
> If you could have a 10x more powerful model you could only access running locally through your terminal, versus a weaker model through a clean web interface, normies will pick the web ui every single time.
More like if you could have a 1.25x more powerful model that you could only access through some weird surveillance megacorps aggressive monetization scheme, or choose from 100 others running open models and accessible through 100 different interfaces pandering to every taste.
Normies will choose the megacorp every time, because that was the one in the tv commercial, and within six months will have left for one of the others in a rage.
The only corporate hope is that the government steps in to ban their competition.
There were many smartphones before both iOS and Android.
While that may be technically true for a strict definition of “smartphone,” there’s no denying the iPhone redefined the concept in a way that its competitors were forced to copy to have any hope of keeping up. Nobody hears the word “smartphone” and thinks of a Blueberry or Treo anymore.
What exactly did the iPhone do better?
That's a subjective question, so I'll give a subjective answer. The browser, for better or worse, was a lot less dumbed down for mobile than competitors, the stylus-less touch interface reduced UI friction and the odds that you'd lose a critical (if inexpensive) component, and the slew of contemporary iPod users could easily migrate their libraries over.
Exactly 4 months ago, the marketshare on openrouter was 60%-40% in favor of closed models. Now it's 63%-37% in favor of open models. On March 19th, the open models processed 888B tokens in aggregate, yesterday, they processed 4.19T tokens in aggregate. That's almost 5x in 4 months! I can't think of the right intensifier to describe this level of growth.
If you are looking for more details (as inferred by openrouter data), I built a dashboard that updates daily: https://dirac.run/labs-market-share
would love to see a statistic by model, and maybe some sort of classification to get a sense of how good the model is and how much it costs.
edit: this exists https://artificialanalysis.ai/
Interesting to see, but I also think more and more usage is moving towards subscriptions, which isn't captured by this metric.
(both my personal and corporate use has done exactly this)
This right here is going to be considered one of the first major signs of the downfall of closed models years from now.
And look, if you disagree with me PLEASE tell me why. What moat do these companies have? I genuinely want to know because looking at the spend for companies like OAI and Anthropic with no actual moat I can identify is actually driving me insane.
I think the frontier AI companies think you're missing key details:
- they can still discover entire new untapped markets for AI (that, potentially, only their models can unlock)
- they can find (novel, unique to them) ways to drive down the cost of running their models
- they can provide other ancillary value (e.g. write better harnesses) because of their expertise, and then charge for that value
I'm probably missing a few bullet points also. However, none of those are moats (or at least not yet) ... I'd consider them more like bets. The frontier AI companies are betting "the house" on them, and if they pay off they could, hypothetically, make them financially competitive.
> The frontier AI companies are betting "the house" on them, and if they pay off they could, hypothetically, make them financially competitive.
They are not betting the house, they are betting the American economy on it. When this crashes it will take everyone down.
I've been keeping my cash/stock ratio a bit higher than usual recently because I'm waiting for the bubble to burst. My "stock" side is mostly a company I work for that is riding the wave.
The moat is enterprise contracts and artificial friction moving between harnesses. Moat is a strong word, more of a puddle.
If we use the same logic as the AI boosters and just assume we're in exponential growth, that means in a year open models will be handling 523T tokens.
> Mozilla exists because one company tried to own the front door to the web, and an open community rose up to make sure it never could.
I'd say that the front door to the web is pretty much owned by Google and Apple at this point given Firefox current marketshare. And maybe that's enough, maybe a future where a low percentage of open models keep the rest of the system honest but that doesn't seem the argument of this article
It's also just a very cherry-picked framing
Mozilla exists because one company owned the front door to the web, and another company abused their market position to push their free (as in beer) browser. Mozilla is the phoenix rising from the ashes of that first company.
Then another company came along, abused their market position to push their free browser, demolished Firefox's market share but keep handing them cash to avoid the appearance of a monopoly
Mozilla exists because Google gives them billions to keep Google as default search engine.
And to keep around a concurrent browser with full adblock abilities so they can cripple their own without too much of an outcry.
Do you think Firefox development is unsustainable without this substantial stipend?
As someone that's generally for the proliferation of open models, I want to take this seriously, but it's really difficult when it was clearly written by AI.
I guess they fired whoever used to write copy for these things.
Edit: to be clear, I'm not trying to just dunk on them, I think it's actively hurting their own point to do this, and counter-productive when people can easily clock it - it makes some percent of the audience immediately tune out.
> Parity reached. The contest is one layer up.
I want to vomit reading that.
Agreed. Maybe we've become jaded to the writing style of AI, but it reads as disingenuous.

the pdf is easier to read
It sure is nice to see that Mozilla is still doing all that they can to keep on top of current trends, except developing a decent privacy-focused web browser for developers and power users.
Firefox's AI Chatbot feature only proposes one open model provider (Mistral) and zero local option. They're not walking the talk.
They get paid half a billion a year to do exactly what they have been doing and keeping FF at <5% of market share on desktop and 0% on mobile.
But they supply all the source for those projects to flourish and have an ecosystem of their own: Librefox, Iceweasel, Reynard, etc, etc.
That's a very low bar, though. Chromium is open-source too and has a bunch of privacy-focused forks such as Ungoogled Chromium, Brave and Chromite.
Yes, Firefox itself is a “general purpose” browser, and that’s probably for the best in terms of wide market appeal. Other developers have taken the engine and made power-user-focused browsers with it. Lately I’ve fallen in love with Zen (though after 2 months of use its pinned tabs features still confuse me a bit).
https://zen-browser.app/
I’m not ready to celebrate the victory of open models just yet considering all the good ones are built by private, VC funded companies. How long will they continue to be charitable? And what’s their actual business model once the money stops and investors start demanding returns?
> The cloud era already ran this experiment: proprietary APIs plus data gravity made exit punitive. The repatriation wave is the receipt.
Some sentences smell a lot like AI.
Virtually every article about AI these days is written by AI. It's obvious why, but boy is it nauseating to read
The design and layout made it harder to read than it needed to be.
Regardless, the inference costs dropping almost 50× is really amazing to see. And now Kimi K3 release has shown how open models are getting closer to the frontier level already. Open source AI is moving a lot faster than Anthropic and OpenAI would have expected lol.
Almost all about open weight, but the title says Open Source.
Gemini had a pop-up on my phone today, asking me if I wanted to "bring Gemini up to speed" by importing conversations from my other AI apps. This tells me that Google is threatened, or data hungry as always, or both. Open source AI, Anthropic, and OpenAI, knocking on doors.
I don't love the appeal to romanticism portrayed in this article.
mozilla only began babbling about open source ai when they got their teeth extracted for free via the entire community giving them the curbiest of curbstomps.
i still use firefox but hot damn did they utterly fail to read the room initially. the only other company i can think of in recent memory -- besides sony cutting out discs -- is logitech when their ceo began gibbering about a subscription mouse or microsoft and its copilot button(s).
Quick fix for the font, which many people are (rightly) complaining about.
The issue is that all of the text is a quote, and that renders enormous. That’s probably fine for a tiny quote amongst more text, but here it is jarring.querySelector/querySelectorAll() are great for plucking out deeply nested elements but if all you need is to find all elements of a certain class and the API gives you a tool to do exactly that, why not do that instead of reaching for the general-purpose Swiss army knife? Sure, the execution speed difference may be only measurable in microseconds, but it takes about the same amount of time to type so why not use the specific tool?
Maybe its the wildfire smoke in my eyes, but that font choice feels aggressive.
Forget aggressive, I just find the main text font harder to read (vs. ... you know ... a normal font).
It's their own fonts: Mozilla Headline and Mozilla Text.
No idea why they'd be using the display font for the abstract though, that kind of defeats the whole purpose. It's supposed to be quirky and bold, but used far more sparsingly.
It's AI slop
It appears open models were used to create this slop.
That opening is so hard to understand what they are trying to say, from the font and how it's written. It took me several times rereading to even grasp.
Plus the article is filled with cryptic things like:
What?! Is it a meta answer to "the state of open source AI" question?From the title of a chart:
> The venture-funded open-source ecosystem: total disclosed funding, USD M
> Bars grow as you scroll.
The bars, in fact, don't grow as you scroll. And I don't even see why they should.
On my device, bars grow as I scroll. I want your feature, being able to just scroll the static page without elements jumping around.
> The bars, in fact, don't grow as you scroll. And I don't even see why they should.
On my device, they grow as I scroll to them.
I think it’s supposed to mean “open source is easily shipped, but open source is hard to deploy”? Or perhaps “deploys hard” is a figure of speach, as in “we are deploying this open source and we are deploying it /hard/“? I don’t know, it’s not good.
This is truly some proper slop. The "PRODUCTION RATE BY COMPANY SIZE" graph has bars that start offset from the text underneath them, which LOOKS like a mistake that happened due to word wrap, but if you visibly compare the 54% to the 55% bars they seem to have compensated for this?! I can't tell if his was on purpose or accident and it's impossible to take the data seriously!
This is on mobile in portrait. In landscape the text doesn't wrap or offset anything.
So good at style, so weak on substance
This new trend of content appearing while scrolling down is so terrible accessibility-wise, I do not understand how Mozilla of all institutions would do it.
Not every trend needs to be followed. Have some backbone. You receive donations to have that.
___
Apart from the website being - frankly - bullshit, the content is also - frankly - bullshit.
It's just on the frontpage because the title says "open source AI".
> This new trend of content appearing while scrolling down is so terrible accessibility-wise, I do not understand how Mozilla of all institutions would do it.
Could you explain what is wrong with the accessibility of this page? All the content is included in the html payload, so it is accessible to screen readers and text-based browsers; and as for the "reveal" effect, it seems to respect user's choice of "prefers reduced motion" and is disabled when that is user's preference.
> it seems to respect user's choice of "prefers reduced motion".
Cool, that I didn't check, because it is impossible to enable that setting, as it breaks _huge_ amounts of websites.
I'm not aware of a way to enable it selectively, but one could also just display the content at all times. It's a static page. It's static content. None of this makes any sense.
___
The idea behind that style of gradual reveal is probably some kind of storytelling, but the only story it tells is that mozilla is wasting donations on people with incorrect opinions that could be used on.. idk not building torment nexii?
Seems quite odd to use OpenRouter as “proof” that open weights models won. If you’re using OpenRouter, you’re already looking to bypass frontier models. To suggest there’s no longer a tradeoff simply isn’t true. But this isn’t the first time I thought Mozilla was a less than trustworthy source of information.
I think "If you’re using OpenRouter, you’re already looking to bypass frontier models." is false. Our company uses both Claude subscriptions and OpenRouter ... and a lot of what we use OpenRouter for is more Claude.
We do a little exploration with other models through it, but it's not at all accurate to say we use it because we are "already looking to bypass frontier models".
Is the CTO a bot?
Can a vending machine operator do better than Mozilla management? - that's the golden question.
> Open weights are no longer a compromise. They are where the work happens.
> They require owning the layers above it — the harness, the memory, the permission model — while those layers are still open.
> Open isn't a vendor choice. It's a sovereignty choice.
There isn't any open-source AI. There is Open AI (not to be confused with the closed company called OpenAI, which was unable to trademark its name). There's no open source AI both because the open source community doesn't have the resources to train a useful AI and because AI doesn't have source code.
Is training code and dataset not source?
Are they open?
This is just wrong on multiple levels, the open source model ecosystem is very much a thing.
I don't know of any useful model that would match the usual definition of "open source". That is, where everything needed to build the thing is provided, such as the training data and code. Not that it would be tremendously useful anyways considering how expensive training a model is.
I much prefer the "open weights" term. It is not open source in the sense that you only get the finished product, not the actual source, but it is still open in the sense that it is not only accessible as a service.
For an analogy, take Quake for instance. When it was launched, its game server was available as an executable, so you could run it your machine, but that didn't make it open source. Only much later it was released as true open source software.
There are fully open models, it's just not as common because that's basically giving away the sauce, which is non-viable for many.
eg: https://allenai.org
The UI is really hard on the eyes. Personally, I think the font size is way too big, and the animation timing feels off. If this is a benchmark page and not a product page, I feel like the information should be scannable at a glance. The UX is bad.
I'm unsure what it is about AI developers seemingly not having eyeballs. The Hermes Agent website is absolutely eye-searing and the application itself resembles some sort of weird "RETVRN" greek-styled travel agent website.
https://hermes-agent.nousresearch.com/
Really wish websites weren't allowed to force smooth scroll on. Hijacking basic browser functionality is so hostile.
Oh that's easy: they outsource design to the LLM, which doesn't have eyeballs.
I agree 1000%, Mr. Jake.
I use hermes only ever saw their repo. Atrocious. I was sure you were exaggerating.
Feels like a mobile website that was never optimized for desktop usage.
Title: The state of open source AI.
First sentence: In New Zealand's far north, a Māori broadcaster...
...oh boy, that's all you need to read to know what kind of media diet the writer is on.
Normally I'd agree, but the rest of the sentence does actually discuss open models and their use cases.
Just like how the web was won?
I think Mozilla is chasing a past formula, but the projection isn't linear enough to remain consistent, and the critical parts of the outcome, utter centralization of the market dominance of the three C's, are left out of the equation.
We might get the consolation prize, a few nerds having competitive alternatives to applaud, but we will be left with the hidden costs: stagnation by bloated market leaders, consumers and businesses pouring trillions of dollars into the commercial offerings while open development wonders where money comes from, and the leakage of these imbalances into political and social spheres.
If we follow a Mozilla template and get to the peak of Mozilla's success at the web, look at what that really is. Facebook, Amazon, Google etc are orthogonal to that equation.
"Open won"... to be fair cause "google paid it".
I think the fact that Mozilla survival model ultimately depends on Google's money means Google is keeping a corpse propped up just to have a defense argument that a browser competitor still exists, so they don't get hit with monopoly regulations.
Particularly in this day in age when the FF market share is down to low single digits
Haven't been following the articles and snippets we get from these labs about training their models for a while. But I'm guessing the latest chinese models are way less based on distilling? If not, then your speed of progress is still limited by the two labs (which we are collectively, in various forms subsidizing).
This is really insane to me.
There's nothing practical about open-source models yet that makes them even remotely comparable to closed frontier models.
All the hype around GLM, Qwen, now Kimi.... Are people really this naive that they believe these reports or, more worringly, are people NOT using these models and seeing the HUGE gap that still exists?
Take a task, any medium-sized task, decently scoped that you'd trust to give to Sonnet to finish without a hitch. Now give it to ANY open-source frontier model and watch them struggle and go in circles while failing tool calls and randomly assuming things.
Open-source is and has been amazing but its so hard to deploy reliably and at scale and there's still big problems in the underlying models with instruction following and tool calling that makes it basically unusable for production workloads at a decent price point...
> Take a task, any medium-sized task, decently scoped that you'd trust to give to Sonnet to finish without a hitch. Now give it to ANY open-source frontier model and watch them struggle and go in circles while failing tool calls and randomly assuming things.
Claude used to be much worse than it is now, just as bad the open weights models are. And the open weights were worse. The labs will also try to keep the lead, but at some point people start seeing real value from open models. Maybe you say they're not ready yet for medium tasks, but everyone sees the writing on the wall.
I hope you're right and I want you to be right, but, even seeing the current hype around local models, etc... and open-source models, I think the industry is currently under a big confusion where they see the benchmarks of things like Kimi, GLM, Qwen, they play with it via opencode, and they think like: "Wow this is pretty good, I want to deploy this". But they don't understand how the KV cache grows over time and can take almost as much memory as needed for a 30B param model, they dont understand that a quantized model WILL NOT be the same as a full precision one, and they surely don't see the engineering work needed to serve inference to even tens of customers at a decent quality and latency level.
The biggest moat of these giant labs and models is increasingly shifting towards deployment capabilities and (debatably) having better (proprietary) harnesses.
The models themselves can be impressive on benchmarks, but unless they can be served reliably to customers either at scale, hosted somewhere, or even on edge with predictable latency and memory usage, then frontier will always be leading.
It sounds like you're focusing on the problems of running local models, or running models yourself, but I don't think that many people seriously expect near term improvement on that, it's definitely more just hopeful thinking there. That's not what I meant to address, and I also am in more of a "wait and see" mode.
But at this point we do expect that open weights _hosted_ options become feasible for the tasks they're using the frontier models for. And because of the lack of "legal monopoly" (intellectual property of whatever kind), they're way cheaper, not mention more flexible.
The launch of the tinker platform from Thinking Machines is an example of the "more flexibility" part that people want (and they chose to make their model open weights, maybe because this is the angle they want to push).
At this point I think it's realistic enough that the ball is in OpenAI / Anthropic's court to figure out how to respond to this threat to their business model.
That said, I think it's concerning that there are apparently only a couple of providers of hosted open weights inference, due to the complexities of doing so (per Dax from OpenCode's tweets).
Have you really given GLM 5.2 an honest go ?
If your doing things the closed models won't let you do; its the whole ball game.
