    The installation method they officially propagate is dangerous. ``` curl -fsSL https://mimo.xiaomi.com/install | bash ```

    This is usually a PoC (Proof of concept) way to install something on a temporary container or temporary VM, but not for production use during daily desktop operation.

    I was hoping their documentation would provide better installation instructions. But strangely, only for Windows do they recommend "npm install -g @mimo-ai/cli," which is a much better approach to managing installed packages.

    For Mac/Linux, they have the strange recommendation to use the dangerous "curl <some_url> | bash." Quote:

    > (for the best experience, Mac users are strongly encouraged to use iTerm or the VSCode Terminal) > curl -fsSL https://mimo.xiaomi.com/install | bash

    Isn't Unlimited Context pretty difficult to promise? What exactly do they mean, could I just have two agents locked into a TTRPG back and forth forever?

  • greenleafone7 a minute ago

    It was already open-source `https://github.com/anomalyco/opencode`

  • porphyra 16 minutes ago

    Pretty neat that you can just install it and start using it (at a Sonnet 4.6-level model) without needing to sign in or pay.

    Typically, Chinese websites are a big pain to log in or sign up because they require a +86 phone number due to legal reasons. Being able to use it without having to make an account is amazing for friction reduction. I could probably even just install it onto new machines to help with set up.

    I wonder how they are gonna detect and block abuse though?

      So funny I have noticed how terrible the signup is on all these Chinese models, companies etc. Always wonder why it is such an easy process. Like QQ, Tencent etc demos Ive seen past year

  • DanMcInerney 2 minutes ago

    I've worked a lot with MiMo in my project that pits LLMs against each other in games (clankerfights.ai). It is a very very good model for the price. MiniMax I'd say is smarter, but MiMo really touches near pareto frontier.

    Since the link is in Chinese: MiMo Code is Xiaomi’s AI agentic coding harness.

    “ MiMoCode is a terminal-native AI coding assistant. It can read and write code, run commands, manage Git, and use a persistent memory system to keep a deep understanding of your project across sessions while continuously improving itself.”

    GitHub link (English): https://github.com/XiaomiMiMo/MiMo-Code

    @dang might be better to link to the GitHub, and not for language reasons.

      You can change the language via the header: The rightmost option is a language dropdown.

      It's a client-side change and doesn't impact the URL so users must manually change it each time they visit the site though

      • ComputerGuru 2 hours ago

        Thanks, I missed that on first glance and did manual translation.

        Not sure why my iPhone shows an option to translate website but all the destination languages to pick from (I have multiple languages installed), including English, are greyed out. iPhone does support translating from Chinese (Simplified or Traditional), and the button to translate website isn’t greyed out like it is for unsupported/unrecognized languages. Might be an iOS 27 bug, because it is working on other websites?

      • ramon156 2 hours ago

        Why not persist it through a query param? Or a lang param for that matter

        • danesparza an hour ago

          Feels like maybe you're just noticing this because it defaults to Chinese. Is that true?

          How many sites do this but you don't notice because they default to English?

          • psychoslave 26 minutes ago

            Personally, none, I’m not English native. I didn’t notice the locale switch, but mostly because the look of the website was so beautiful I didn’t pay attention to menus. I wonder if ideograms keeps looking so beautiful once you learned to decode them. I never found Latin script to be particularly beautiful, and to this date Arabic script remains my favorite one in term of esthetic (I can’t read Arabic ever).

            • klausa 15 minutes ago

              This is not exactly what you’re asking about, but I started learning Japanese when I was in the middle of playing Cyberpunk 2077 (for unrelated reasons); and I gotta tell you; realizing that 98% of the Japanese text everywhere in the game was just “hotel” or “karaoke” definitely took away some charm from it.

          • rplnt an hour ago

            But what if you have English configured as a preferred language? Isn't that what it's for? Wouldn't it make sense for a website to respect that (when available)? I hate that google.com doesn't and defaults to random languages based on IP.

        • sheept an hour ago

          Language support was probably an afterthought since their target audience all read Chinese

    > MiMoCode is built as a fork of OpenCode. It keeps all core OpenCode capabilities (multiple providers, TUI, LSP, MCP, plugins) and adds persistent memory, intelligent context management, subagent orchestration, goal-driven autonomous loops, compose workflows, and self-improvement via dream/distill.

      Sounds like they slapped in a bunch of common plugins and released it as a product to promote the free-for-a-limited-time use of their new coding AI service.

      • ignoramous an hour ago

        > promote the free-for-a-limited-time use of their new coding AI service

        Not sure which "free" service you're referring to, but MiMo v2.5 Pro is plenty capable & (after its recent 70%+ price drop) one of the most affordable options in its class (DeepSeek v4 Pro, MiniMax M3, & Qwen 3.7 Plus). I read somewhere that Labs are incentivized to implement custom harnesses because each model has its strengths, quirks, & blindspots (like Qwen forking Gemini CLI)?

          That was a good call. Gemini CLI is dead.

        So, basically the same thing silicon valley has been doing for the past half decade.

    macOS binary (mimocode-darwin-arm64.zip ) seems broken: "“mimo” is damaged and can’t be opened. You should move it to the Trash."

  • tietjens an hour ago

    This is my favorite of the Chinese models I have tried. I think it would be hard to know if I was using Opus of MiMo if blindfolded in many instances.

    • denysvitali 44 minutes ago

      Yes, but this has nothing to do with MiMo (the model).

      This is what Claude Code is to Claude

      • djsamseng 8 minutes ago

        I found it relevant and actually just the information I was looking for. Having a highly recommended model behind the tool makes it worth further investigation.

    • dannyw 44 minutes ago

      MiMo Code is not a model, it's a harness like Claude Code / OpenCode / Codex (which is still open source, Apache 2.0, btw).

      You might mean the MiMo-V2.5-Pro model?

    "MiMoCode is built as a fork of OpenCode."

    Why not just contribute to OpenCode instead of creating a clone :/

    • mythz 2 hours ago

      Because they want to optimize it for their models and don't want to be blocked by waiting for PRs to merge or be rejected.

      There's plenty of reasons to start your own fork that you have full agency of, as long as the OSS License is maintained anyone will be able to benefit from any new features they want to make use of.

      • dannyw 41 minutes ago

        This is the beauty of open source :) KHTML -> WebKit -> Blink is a good example.

        • bigyabai 8 minutes ago

          KHTML is dead now, though. It was basically embraced, extended and extinguished by Apple and Google, who both wanted to take away the leverage of the community.

          Today, legacy KHTML maintainers are boxed-out of upstream decisions that might prevent Manifest v2 from swirling down the drain. I'd argue the story isn't very beautiful anymore.

      I think there's simply too much changed.

    • konart 2 hours ago

      To go a different path perhaps? You can't expect that all your ideas will land into a main repo and you really want to implement your vision while using a sane base.

    • rurban 28 minutes ago

      Opencode sits on a ton of important PR's, so they didn't want to wait. Everybody else switched to omp (oh my pi) already.

    • postalrat an hour ago

      OpenCode can merge in all their changes if they want.

    • dartharva 23 minutes ago

      Could just be a courtesy - Americans tend to be rather suspicious and hostile to contributions coming from China, and it might draw unwarranted attention from agencies and bad media.

    • orangeisthe 25 minutes ago

      It's controlled by a different organization; in particular a startup in a "competing" space.

  • nmfisher an hour ago

    Good timing, I was looking for alternatives earlier today. opencode didn't install properly and I wasn't a fan of oh-my-pi and nanocoder.

    MiMo code (via my z.ai coding plan) is very pleasant so far, nice UI and seems to respond faster than Claude Code. It might be injecting much less cruft into the conversation.

    I also got access to the mimo-2.5-pro ultraspeed model yesterday, which is really quite snappy. It does cost more than DeepSeek, though, so I'm not sure whether it's worth it yet. Definitely fast though.

    • cyanydeez an hour ago

      is it local compatible and does it have telemetry?

      • qskousen 27 minutes ago

        it does have telemetry, enabled by default, that sends metrics to tracking.miui.com, including what model you are using. it can be turned off by environment variable (MIMOCODE_ENABLE_ANALYSIS=false), and yes it still has all the normal OpenCode provider logic so it will work with other/local models. it also automatically looks for updates and fetches a mimo model list, including when the telemetry is off, though those can also be disabled.

        telemetry enabled by default and named "analysis" is not great.

    I'm kind of surprised the demo UI is macOS. Are they mainly using Apple products to develop these things?

    • rurban 27 minutes ago

      The more advanced devs all use apple laptops, sure.

    It's interesting that it renders Chinese in a TUI. I wonder if that breaks anything that assumes a character is always a column wide.

  • psychoslave an hour ago

    Is that Open-Source like, run it locally, no phone home included, or open source like the thin front-end layer is all that is actually open-source but it’s an empty shell without the remote API it relies on?

    • passive an hour ago

      They default it to talking to a free version of their model (which is incredibly cheap if you decide you like it.)

      But it seems trivially easy to run it against local models. Their onboarding guide offers that option, though I have no idea if it changes any functionality.

    • Pxtl an hour ago

      The latter. It looks like it's meant to be a batteries-included agent to promote their free-for-a-limited time AI service that it connects to by default.

      • psychoslave an hour ago

        Ok, fair enough compared to the rest of the proeminent actors I guess, but quite confusing from dev point of view. Lately I started to experiment with model like Qwen2.5 on local. Good enough to ask simple question, but didn’t manage to do anything remotely close a agents I started to experiment with through Copilot.

        • Pxtl 3 minutes ago

          qwen3.5 9b runs okay on my 12GB gaming GPU. It's very stupid as a coding agent but it's possible to get useful work out of it.

  • pelagicAustral an hour ago

    I got an invite to test their ultra fast model only to be geofenced when trying to use it. Pff!
