Xiaomi MiMo-Code Review: What It Is & How It Compares
The most important thing to know about MiMo-Code is what it is not: it is not a language model. Xiaomi's XiaomiMiMo/MiMo-Code repository is a terminal-native AI coding agent — a CLI built as a fork of OpenCode, tagline "Where Models and Agents Co-Evolve." The models live separately, on Hugging Face as the open-weight MiMo family. This review untangles the two, lists what MiMo-Code actually does, flags the license nuance most write-ups miss, and puts the underlying models next to the other open coding options — with every benchmark marked vendor-reported. All details are as of July 2026.
What MiMo-Code actually is
MiMo-Code is a terminal-native AI coding agent — a CLI framework, not a language model. The repository at XiaomiMiMo/MiMo-Code is built as a fork of the open-source OpenCode project, and its README describes it as an agent that adds persistent memory, context management, subagent orchestration, goal-driven autonomous loops, compose workflows, and self-improvement ("dream/distill") on top of the OpenCode base. The current release is v0.1.5, dated July 7, 2026.
The repo tagline — "MiMo Code: Where Models and Agents Co-Evolve" — is the clue to Xiaomi's framing: the agent tooling (MiMo-Code) and the open-weight models (the MiMo family on Hugging Face) are shipped as two separate things that are meant to improve together. If you came looking for "the MiMo coding model," you are actually looking at two artifacts, and this review keeps them apart.
Agent vs model: the two things called MiMo
"MiMo" names both a coding agent and a family of models — conflating them is the single biggest source of confusion. Here is the clean split, straight from the primary sources:
| Aspect | MiMo-Code (the agent) | MiMo models (the weights) |
|---|---|---|
| What it is | Terminal CLI / coding agent | Open-weight LLMs (MoE) |
| Where it lives | GitHub: XiaomiMiMo/MiMo-Code | Hugging Face: XiaomiMiMo |
| Ships weights? | No | Yes (Safetensors) |
| Ships benchmarks? | No | Yes (vendor-reported) |
| Built on | Fork of OpenCode | Custom MoE architecture |
| License tag | MIT + Use Restrictions | MIT (on cards) |
In practice: MiMo-Code is the thing you install and run in a terminal; the MiMo models are what you (optionally) point it — or any other OpenAI-compatible client — at. The rest of this article treats each on its own terms.
What MiMo-Code does (feature by feature)
It is OpenCode plus a layer of Xiaomi-specific agent machinery. Because it is a fork, it inherits the OpenCode core — multiple providers, a terminal UI (TUI), LSP integration, MCP support, and plugins — and then, per the README, adds:
- Persistent memory — state that survives across sessions rather than a single-shot context window.
- Context management — deliberate control of what goes into the model's window.
- Subagent orchestration — delegating sub-tasks to child agents.
- Goal-driven autonomous loops — running toward an objective rather than one prompt at a time.
- Compose workflows — chaining steps into repeatable pipelines.
- Self-improvement ("dream/distill") — the repo's named mechanism for the "co-evolve" tagline.
Those last items — subagents, autonomous loops, self-improvement — are how MiMo-Code differentiates from vanilla OpenCode. Note that these are Xiaomi's naming and framing for one project, not an industry standard; treat "dream/distill" as this repo's convention rather than a general term. If you are comparing terminal coding agents more broadly, our Claude vs Cline breakdown and the best LLMs for AI agents guide cover the wider field.
Install and provider setup
MiMo-Code installs three ways per its README — but copy the exact command from the repo, not from a blog. The README lists a one-line curl … | bash installer for macOS/Linux, a PowerShell installer for Windows, and an npm install -g package for any platform. Install-script URLs and package names change, so open the XiaomiMiMo/MiMo-Code repo and copy the current command — and never pipe an unverified curl … | bash straight into your shell.
On first run, MiMo-Code offers a built-in "MiMo Auto" channel — a free-for-limited-time option that gives a zero-configuration start. Important caveat: the README does not state which underlying model powers MiMo Auto. Because the tool also supports any mainstream OpenAI-compatible provider, you can instead route it to a model of your choosing. Pointing it at a gateway looks like any other OpenAI-compatible endpoint:
# Route MiMo-Code (or any OpenAI-compatible client) through a gateway
export OPENAI_BASE_URL="https://www.datallmlab.com/v1"
export OPENAI_API_KEY="sk-..."
# then select an open coding model, e.g. glm-5.2 or gpt-oss-120b
That is the same pattern used by every OpenAI-SDK-compatible tool — see the OpenAI-compatible API guide for the drop-in details, and routing & failover for keeping an agent alive when one provider blips.
License and availability — read the fine print
MiMo-Code's code is MIT, but "MIT" is not the whole story — and the same caveat applies to the model cards. The README states plainly that while the source is under the MIT License, usage is also subject to separate Use Restrictions, the MiMo Terms of Service, and a trademark policy. That means it is not pure permissive MIT for every use case.
The same nuance shows up on the Hugging Face model cards: each lists license "MIT," but that one-word tag can understate additional Xiaomi restrictions bundled alongside the MIT-licensed code. Our take: if you are evaluating MiMo — the agent or the models — for anything commercial, read the actual LICENSE and terms files in the repo and on the model cards rather than trusting the card's one-word summary. Availability itself is not in doubt: the tooling is public on GitHub and the weights are downloadable on Hugging Face (more below).
The underlying open-weight MiMo models
The models are genuinely open-weight — large sparse MoE architectures, downloadable in multiple precisions. The XiaomiMiMo Hugging Face organization hosts the family: MiMo-V2.5-Pro, MiMo-V2.5, MiMo-V2-Flash, MiMo-V2.5-ASR, MiMo-Audio, and base variants. The cards expose downloadable Safetensors in F32/BF16/FP8/FP4, and MiMo-V2.5-Pro reported roughly 101,692 downloads in the prior month — real weight availability, not an API-only tease. The spec/positioning table (all figures from the model cards):
| Model | Total / active params | Context | Notable | License (card) |
|---|---|---|---|---|
| MiMo-V2.5-Pro | 1.02T / 42B | 1M tokens | 384 experts (8/token), SWA + global attn | MIT |
| MiMo-V2-Flash | 309B / 15B | 256k tokens | SWA/global 5:1, Multi-Token Prediction | MIT |
| MiMo-V2.5 | ~310B / 15B | — | Native omnimodal (text/image/video/audio) | MIT |
The vendor-reported benchmarks (from the model cards — self-reported, not independently verified):
| Benchmark | MiMo-V2.5-Pro | MiMo-V2-Flash | MiMo-V2.5 |
|---|---|---|---|
| MMLU-Pro | 68.5 | 84.9 | — |
| GPQA-Diamond | — | 83.7 | — |
| AIME 2025 | — | 94.1 | — |
| SWE-Bench | 35.7 (AgentLess) | 73.4 (Verified) | 56.1 (Pro) |
| LiveCodeBench-v6 | — | 80.6 | — |
| Terminal Bench 2 | — | — | 65.8 |
All numbers above are vendor-reported by Xiaomi on the respective Hugging Face cards (V2.5-Pro, V2-Flash) and should be treated as self-reported until independent evaluations land. Blank cells mean the card did not report that pairing, not a zero.
How it compares to other open coding options
Compare like with like: the agent against other agents, the models against other open weights. As an agent, MiMo-Code competes with OpenCode (its own upstream), Cline, and Claude Code; its differentiator is the added memory/subagent/self-improvement layer rather than the editor loop itself. As models, the MiMo weights sit in the same open-weight bracket as GLM, gpt-oss, and DeepSeek — and on Xiaomi's own numbers they are competitive (V2-Flash's SWE-Bench Verified 73.4 is a strong self-reported score), but those numbers are unverified.
| If you want… | Consider | Why |
|---|---|---|
| A terminal coding agent with memory/subagents | MiMo-Code | OpenCode base + Xiaomi's agent layer |
| A proven open coding model with an ecosystem | GLM-5.2, gpt-oss-120b | Widely served, independently benchmarked |
| A biggest-context open MoE (vendor claims) | MiMo-V2.5-Pro | 1M context, 1.02T/42B — self-reported |
| A frontier hosted coding model | Claude Sonnet 5 | Top agentic coding, not open-weight |
For the head-to-head on the established open field, see the best coding LLM in 2026 and our DeepSeek R1 vs gpt-oss comparison; for the broader roundup of downloadable models, best open-source LLMs. If you plan to self-host a MiMo-scale MoE, note these are very large models — our run LLMs locally and gpt-oss-120b hardware requirements guides set realistic expectations.
Who MiMo-Code is for (and who it is not)
An honest read: MiMo-Code is for the tinkerer who wants an OpenCode-plus agent and a free on-ramp — not (yet) for the team that needs verified numbers and clean licensing.
- Good fit: you already like OpenCode and want the extra memory/subagent/self-improvement layer; you want a free, zero-config way to try an agentic coding loop (the MiMo Auto channel); you are experimenting with open-weight MoE models and want first-party tooling to drive them.
- Poor fit (for now): you need independently verified benchmarks before adoption — everything here is vendor-reported; you need unambiguous permissive licensing — the MIT tag comes with Use Restrictions and a ToS you must read; you need production stability — v0.1.5 is early, and the free channel's served model is unnamed and time-limited.
- Undecided? Keep the agent and the model choice separate. Run MiMo-Code (or any OpenAI-compatible agent) against a well-understood, well-supported model through a gateway, so you get the tooling without betting on unverified weights. That is the lowest-risk way to evaluate the "co-evolve" idea.

FAQ
Is MiMo-Code a model or an agent?
An agent. XiaomiMiMo/MiMo-Code is a terminal-native CLI built as a fork of OpenCode; it ships no weights and no benchmarks. Xiaomi's actual open-weight models (MiMo-V2.5-Pro, MiMo-V2-Flash and others) live separately on Hugging Face.
What license is MiMo-Code under?
The code is MIT, but the README says usage is also subject to separate Use Restrictions, MiMo Terms of Service, and a trademark policy — so not pure permissive MIT. The model cards list MIT too, but read the actual LICENSE files for commercial use.
What model powers the free MiMo Auto channel?
The README does not say. MiMo Auto is a built-in free-for-limited-time channel for a zero-config start, but it does not name the underlying model. You can instead point MiMo-Code at any OpenAI-compatible provider.
Are the MiMo models actually open-weight?
Yes — the Hugging Face cards expose downloadable Safetensors (F32/BF16/FP8/FP4), and MiMo-V2.5-Pro reported ~101,692 downloads in the prior month. V2.5-Pro is 1.02T/42B with 1M context; V2-Flash is 309B/15B with 256k context.
How do I install MiMo-Code?
Per the README: one-line curl on macOS/Linux, PowerShell on Windows, or npm on any platform. As an OpenCode fork it keeps multiple providers, a TUI, LSP, MCP, and plugins. Current release is v0.1.5 (July 7, 2026).
How does MiMo compare to other open coding models?
On vendor-reported numbers it is competitive — V2-Flash claims SWE-Bench Verified 73.4 and LiveCodeBench-v6 80.6 — but treat those as self-reported. As an agent it competes with OpenCode, Cline, and Claude Code, differentiated by memory, subagents, and self-improvement loops.
