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

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

danesparza•58m 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?

rplnt•40m 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.

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).

sheept•57m ago

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

ComputerGuru•1h 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?

"MiMoCode is built as a fork of OpenCode."

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

konart•1h 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.

mythz•1h 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•19m ago

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

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

doctorpangloss•59m ago

have you ever tried contributing a large number of changes to OSS?

Much more information in the blog post this links to: https://mimo.xiaomi.com/blog/mimo-code-long-horizon

I thought this was a wireless/MIMO radio project at first

rickdeckard•1h ago

yeah, was also expecting some disruption in the RF-design space.

Kinda RF-nerd clickbait... :)

fadedsignal•33m ago

I also thought the same lol. It also happened with lora

eunos•4m ago

Well Xiaomi is first and foremost a mobile phone company.

reactordev•1h ago

Looks an awful lot like OpenCode

> MiMoCode is built as a fork of OpenCode.

That’s why

psychoslave•59m 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?

Pxtl•52m 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•36m 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.

passive•29m 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.

emayljames•58m ago

I wonder what the minimum required memory specification is

sheept•55m ago

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.

GodelNumbering•53m ago

> 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.

cyanydeez•37m ago

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

> 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)?

pelagicAustral•45m ago

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

nmfisher•44m 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•38m ago

is it local compatible and does it have telemetry?

qskousen•5m 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.

jadar•30m ago

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

rurban•4m ago

The more advanced devs all use apple laptops, sure.

Who isn’t?

joshmarinacci•27m ago

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.

tietjens•24m 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•21m ago

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

This is what Claude Code is to Claude

dannyw•21m 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?
