    I used to think that way about SVGBench, after all labs can just train on the test set, right? It turns out the task was highly generalizable. Try designing a logo and you quickly see the gap between models visually. Even though there is still a gap between "shiny demo SVG" and actual real-world use.

    Same thing happened with MineBench, basically SVGBench+3D, until that got "saturated".

    Remember spinning hexagon bench[1]? Or the AI World Clocks[2]? Yeah, that used to be hard for frontier models.

    Creating games is the next iteration that still has some signal left. Assets + Game logic + UI + Sound, it let's you assess a model's "taste" very quickly.

    What else is left, once all these benchmarks get saturated?

    I keep seeing Astra make beautiful 3d stuff online, yet when I feed it some old school RuneScape assets (even tried with some very detailed guidelines) and asked it to generate some new plausible assets it failed horribly.

    I think there’s still something really off with current (frontier) models when it comes to creating “novel” stuff? Even 2004 style graphics..

    Or am promoting it wrong?

      It's funny seeing this when I was going to mention runebench

        That's playing RuneScape though? Unless the connection is just that these are both RuneScape related?

      I'm wondering if the following works:

      1. Feed it with Ultima II/III assets;

      2. Feed it with reverse engineering research of such assets;

      3. Ask it to use C++ and SDL2/3 to write a game engine to draw maps, generate enemies, make cities and shops. It doesn't have to be faithful to the game, just something passable is good enough;

      4. See how it works.

      My understanding is that the people are conflating the ability to translate and replicate as creativity/learning. Not to say that its not possible but its a long way to go for sure.

      Did you try blender MCP and prompt for low-poly vertex colored assets?

    Very low quality content. Unsurprisingly pangram 100%.

      I'm not sure myself, there are a lot of comma splices and other such grammar mistakes. Maybe just edited with AI?

    "When a measure becomes a target, it ceases to be a good measure."

    Goodhart's law strikes again.

    https://en.wikipedia.org/wiki/Goodhart%27s_law

    However, what is meaningful is whether something is able to create usefully adjacent output, like "let's make Minecraft, but with marching cubes, subdivision surfaces, and global illumination... and behaviorally accurate pandas..." (or something like that).

    I have an 11 year old, and most of his game ideas are adjacent to other games he's played. He can make those now, or, at least, enough that he can see where it works and where it doesn't.

    Compared to a few years ago, that's pretty cool.

      Pelicans?

      I heard Gemini was fast so I tested the new one, asked it to clone a popular online game. It took 4 minutes, and worked perfectly first try.

      I might need to sit down.

    > That’s the problem, these tests can’t tell you how good a model is anymore because it’s trivial for labs to optimise for exactly these tests by the next release.

    But they don't prove the claim. Are the models amazing at recreating Minecraft, but the second you swap the word Minecraft out with another game or a custom game, it shits the bed?

    That's not what I see. My feed is full of people using Astra to recreate all sorts of games from Diablo to some random idea they came up with, in ridiculously polished detail like animations that would have taken me weeks of iteration in gpt-5.6-sol but it was a single shot by Astra.

  • orbital-decay 2 hours ago

    This sounds unconvincing, because a) pelican test is subjective, there's simply nothing to leak as it has no available direct answers and maybe an extremely faint preference signal, and b) the same small models actually do perform well when you change the subject. Some models are genuinely trained to be better at some domain, such as 2D layouts or vector graphics in this case. It all depends on particular recipes and datasets. Which is the actual reason these tests are poor as vibe checks: they don't do anything to disentangle generalization, memorization, and training preference. One-shotting popular software in particular is definitely not a good test of anything as memorization is going to dominate it.

    AAII is also not very useful, neither is any generic score/benchmark. If you want a weather forecast you aren't looking at the average temperature of Earth.

    (actually when did the term "one-shot" get hijacked to mean something other than "one example"?..)

      I'd argue this is inherently true for every single model today, none of them have completely generalized to be able to solve any task, so whenever people come up with new evaluations and benchmarks, all the models score relatively poorly initially, until researchers start to tune the models to do well in the domains that the evaluations and benchmarks tests, and then we see strong improvements in that domain, which then tapers out to incremental improvements, and some other domain is chosen to be the new focus.

      Models aren't better agents today merely by chance, but because it's explicitly part of the training data. They do well with software because we've talked so much about software on the internet until this point and that's part of the training data, but pit them against problems people don't talk so much about, and if the labs creating and training these models didn't consider those problems, then the model will pretty much suck at it.

      I guess eventually they will literally cover every single task the model could ever come across, at least some variant/permutation of it, but until then every benchmark/evaluation will just uncover "did the labs consider this and who considered it most important before/during training?" basically.

  • senko an hour ago

    I use Minecraft (and Warcraft and an arcade flying simulator) as a silly but directionally correct indication of the models' capabilitites.

    Compare Astra[0] with GPT 5.4[1] which was OpenAI's state of the art just six months ago.

    (all tests on more models with code and prompts available here: https://senko.net/vibecode-bench )

    Yes, it's not a scientific benchmark but it's a good heuristic.

    For a better eval, create a one-page prompt / mini spec related to whatever you're using the LLMs for, and see how well a particular one works for what's important to you.

      I really like these tests for what its worth and I see them on youtube sometimes. I would like to ask a few things though

      TLDR: Basically focusing on recreating pay to win (mobile or otherwise) games and recreating them non pay to win perhaps instead of focusing on recreation of minecraft for benchmarks could have a genuinely meaningful impact, and making these games portable as well could be another interesting idea. [so it can be played on any operating system/device so using web or if native then for (Android/IOS/Linux/Windows/MacOS) using game engines like (Preferably godot)/Unity/UE.]

      Could the test focus more on pay to win games with unique dynamics.

      For example: I literally wanted to create a clash royale recreation because clash royale is a highly pay to win game.

      The game is unique enough to have memories but is pay to win enough that it ragebaits me as to what its current situation is, its so pay to win now. A recreation would have genuine effect whereas yet another minecraft clone wouldn't.

      I have some fond memories of the game and my brother and I used to play it (my brother moreso than me). Also clash of clans and clash royale famously prevented windows users. So I remember downloading bluestacks to play it on laptop but it required 2GB of ram and back then we only had 1GB. (Ironic that we might come back to that time)

      Another question that I have for you which I have been genuinely curious is: who is footing the bill for these benchmarks and youtube videos. What are the economics surrounding it?

      I imagine the bill to run quite hot sometimes and I find running these benchmarks to be quite unaffordable personally.

      I also wish to ask if you have any theories as to why not people on Youtube share their videos. I found this [0] Minecraft clone by Fable 5.1 extremely good yet they haven't shared the source. I am unsure as to what exact reasons might be behind most youtube videos on recreation with AI to not share the actual code. I don't find much rationale in not sharing AI generated code of a recreation of a game especially if one is making a video about it. So thanks for once for actually sharing the output code as well as I surprisingly found it to be a bit rare!

    The benchmark I want to see people adopt is:

    Build a flowsheet based steady state chemical process simulator, then use it to simulate and optimize a full scale oil refinery.

    1) Building a solver engine that works at this scale is not a trivial problem, and the successful ones rely more on heuristics than some categorically different solution approach.

    2) Defining the engineering equations relevant to this task is relies on understanding what level of fidelity is required to answer the questions people ask of steady state process models.

    3) Knowing the thermophysical properties of chemicals and crude oils is possible from the open literature, but the information is diffuse and different correlations are applicable in different situations.

    4) Creating a GUI which converts a flowsheet into matrix math is non-trivial, although a sequential modular approach is a bit easier.

    5) Defining large scale models in such a way that they solve robustly is as much art as science. For example, completely closed recycle loops like refrigeration systems are a nightmare for solvers, so it is often better to define them in an open-loop way.

    6) Optimization involves knowing the relevant commodity prices, but more importantly how to define the constraints on the model so it doesn't just say to produce infinite gasoline.

    7) Troubleshooting the inevitable convergence failures is also as much art as science. There are a large number of diagnostic techniques, but fundamentally you need to be able to relate what is happening during the solver iterations with the intent of your model because more often than not the problem is that you've asserted something impossible, redundant, or irrelevant.

  • SillyUsername 14 minutes ago

    Definitely not.

    It has to be Doom or Crysis, aren't they the ones people usually ask if it can run?

  • srdjanr 15 minutes ago

    I don't remember seeing playstation controller SVGs before, I doubt they benchmaxxed that

  • jere 26 minutes ago

    But they're not recreating Minecraft. They're recreating one of the most common tutorials on the internet that shows a simple voxel overworld and nothing else. That's not Minecraft.

    • lukan 19 minutes ago

      Important distinction, but I would debate the "most common tutorials on the internet" claim.

  • johnsonjo 3 hours ago

    Though I somewhat think some benchmarks are silly like the article says. I saw someone on YouTube recently take a picture of a building across the street from them (seemed like it was in NYC), and asked GPT 6 Astra to make it in blender. It did a surprisingly good job in 30 minutes. So though these benchmarks don't seem to mean much you could always add a touch of randomness to them like the person in the YouTube video did, but the problem with that is how would you compare the benchmarks in any clear way if they aren't even consistent? Regardless it appears LLMs are getting this good at the general task and not just at the particular instances of said task.

    I partially owe my career to benchmarking AI with Minecraft, so, I'm going to disagree with the author on this one. Games are a great way to test a model, it's not that deep.

          Mac here. There's nothing all that interesting going on with the JS on that page, so I would suspect a bug with Firefox and/or your desktop environment.

  • enraged_camel 3 hours ago

    I’ve used Astra for the past day and a half. My layperson’s review is that it is impressive at computer use and 3D reasoning, and fails in similar ways to 5.6 Sol at similar rates when it comes to coding. I have no idea how it scored so high on SWE benchmarks because so far it has been very “mid” as the kids say.

  • alephnerd 3 hours ago

    Most of my and my peers PortCos run their own eval and benchmark sets, simply because they know what they need best.

    The reality is, capabilities have largely converged across foundation models over the last 18 months, and much of the value add is coming from the harness layer itself now.

    This has been the operating assumption for me and my peers, and has largely played out that way.

    That said, this has always been an issue with benchmarking since the very beginning. DB Benchmarks, compute benchmarks, and others that were external facing were always inherently a content and product marketing tool. The actual internal benchmarking used to model, understand, and enhance your product was always a closely held secret.

    Most of these conversations are happening, but largely in person and not on HN.

      > capabilities have largely converged across foundation models over the last 18 months

      For reference, in March '25 the models du jour were Sonnet 3.7, gpt o4 and gemini 2.5 pro. GPT5 was in august '25.

      It's been a while since we've heard the old "models have stagnated". Oh well.

      • tancop 2 hours ago

        It's not "models have stagnated" but "models released at the same time are on the same level". Improvements are still real but the relative gaps between OpenAI, Anthropic, Meta, Grok, Gemini and open models are closer than ever. That doesn't mean progress is slowing down, it's just more widely distributed.

        • NitpickLawyer 2 hours ago

          Ah, I see. I misunderstood then. The thing about "gains come from the harness" made me think about it in that way.

        • alephnerd 2 hours ago

          This, and depending on the workflow and usecase, you don't necessarily need the latest and greatest with the right kind of harness engineering.

          Like everything in engineering, it's about tradeoffs and what works best for your specific problem.

  • raincole an hour ago

    It'd be more plausible if the current SOTA models weren't so good at generating SVG with all subjects instead of just pelican.

    We're witnessing the mission getting fucking accomplished [0].

    @notch Hey Markus, can I get a refund on my alpha distro of minecraft? I think the currency is worth more than it used to be considering how many versions there are now :)
