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?
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.”

@dang might be better to link to the GitHub, and not for language reasons.
(Edit: for posterity, original URL as submitted was [0]).
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
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?
Why not persist it through a query param? Or a lang param for that matter
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?
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.
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.
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.
From github
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.
> 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)?
> 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.
Any english links?
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.
Yes, but this has nothing to do with MiMo (the model).
This is what Claude Code is to Claude
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?
He didn't say MiMo Code

Why not just contribute to OpenCode instead of creating a clone :/
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.
This is the beauty of open source :) KHTML -> WebKit -> Blink is a good example.
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.
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.
OpenCode can merge in all their changes if they want.
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.
Why not?
have you ever tried contributing a large number of changes to OSS?
> Why not just contribute to OpenCode instead of creating a clone :/
It's controlled by a different organization; in particular a startup in a "competing" space.
[flagged]
I don't think that's true? AFAIK OpenCode started as a TUI and their GUI app is Tauri-based, so don't think it was forked from OpenCode. You might be thinking of Cursor
Are you thinking of Cursor? OpenCode is a TUI like Codex.
Do you even know what you're talking about?
OpenCode started as an independent CLI project. Their desktop app is still in beta, and it was never a fork of VS Code.
I believe they contain no code derived from VS Code.
What does “shamelessly forked” mean? It’s literally software meant to be forked lol
There were once two harnesses named OpenCode, one written in Go & the other in Typescript (the more popular one).
Kujtim Hoxha creates a project named TermAI. (SST folks) Dax & Adam join the project, rebrand it to OpenCode with Dax buying the domain, opencode.ai.
Charm, the company behind the original libraries, acqui-hires Kujtim, who moves the project to Charm's organization, leaving SST unimpressed (due to VC involvement?)
Allegations Charm rewrote git history and deleted GitHub comments.
Dax claims ownership of the brand, forks project. For a time, 2 projects named OpenCode exist. Charm eventually renames its version to "Crush".
Back then they were both written in Go too. OpenCode was rewritten in TypeScript after Crush got the rename.
I thought this was a wireless/MIMO radio project at first
Well Xiaomi is first and foremost a mobile phone company.
yeah, was also expecting some disruption in the RF-design space.
Kinda RF-nerd clickbait... :)
I also thought the same lol. It also happened with lora
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.
is it local compatible and does it have telemetry?
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.
That is an incredibly annoying grunge font. And what is the point of the hidden image in the background that reveals under your mouse cursor.
I'm kind of surprised the demo UI is macOS. Are they mainly using Apple products to develop these things?
The more advanced devs all use apple laptops, sure.
Who isn’t?
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.

Looks an awful lot like OpenCode
> MiMoCode is built as a fork of OpenCode.
That’s why
I wonder what the minimum required memory specification is
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?
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.
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.
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.
I got an invite to test their ultra fast model only to be geofenced when trying to use it. Pff!
