MiMo-Code
MiMo Code: Where Models and Agents Co-Evolve
Runssource: GitHubTypeScriptMITcommit 849ca66cc8de
TypeScript, MIT licensed. The project labels itself: ai, ai agents, cli, mimo and mimo code.
MiMo-Code runs. An Argusic agent installed it in 5.3 minutes and hit 6 errors and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.
MiMoCode CLI runs, typechecks, builds SDK, and passes ~2000+ tests across all core packages (agent, config, auth, git, tool, session, cli, server, workflow, effect, actor, history) with only ~15 environmentally-specific failures (umask, Bun version, test isolation).
What the agent ended up with on a clean machine, in its own words. How this is measured
Measured by Argusic on a fresh machine every time. Every number links to its evidence. Argusic Score 60 of 100 (the mean of this project's run scores).

What was measured
From the run that decided this verdict. Every line is a recorded value, not an estimate.
What went wrong, in the agent's own words
The agent's own words, worst first, never rewritten into advice.
- Bun not available in container1.5 minutes
- `write.test.ts` expects 0o644 file mode, got 0o6640.5 minutes
- `collapse.test.ts` Hangul jamo width: Bun.stringWidth returns 2, test expects 4
- `checkpoint-writer-wait-timeout.test.ts`: 10 tests fail when grouped, 0 fail individually
- `node-migration.test.ts` 2 failures: Node build pipeline not set up
- `session-list-visibility.test.ts`: 1 fail grouped, passes individually
- Install time
- 5 minutes
- Cold machine to finish
- 37 minutes
- Errors hit and fixed
- 6 hit, 6 fixed with no human help

What was not measured
The other half, so you can see exactly how far this evidence goes. A gap is printed as a gap and never filled in.
- Peak GPU memory
- this ran on a CPU machine, so there was no GPU to sample
- Behaviour over a long run
- each attempt uses the smallest documented settings and a fixed time budget, so this measures whether it runs, not how it holds up under load
The end of the recording
The last lines of the terminal session that decided this verdict, exactly as they were recorded.

Replay the whole session, every command from a clean machine to this point.
How it was tested
One agent, one container, no human help. It installs the project the way its own documentation says to, runs it, and fixes what breaks. Everything below is recorded as it happened: the terminal session, the log and the exact commit. The full method.
Strengths and limits
Measured facts, not opinions. How this is written.
What went well
- Reached a running state on a clean machine, with the session recorded.
- Installed in 5.3 minutes, faster than the median of the 45 comparable projects Argusic has measured.
- Recovered from all 6 errors without a human stepping in, which says the failures are documented well enough to solve.
- Ran without a GPU, so it does not need one to start.
- Licensed MIT, as reported by its host.
- Measured 2 times, so the result is not a one-off.
Of the 46 ai projects Argusic has installed and timed, MiMo-Code was the 22nd fastest to reach a running state, and 37 of 46 reached one at all.
What it is a reasonable choice for
- Trying it on a laptop or a small server: it reached a running state without a GPU.
- A quick evaluation: it was running 5.3 minutes after the clone.
Also tested, in the same area
Every one of these was installed and run by Argusic on a clean machine. Nothing appears here that was not tested.

[](https://argusic.com/subject/mimo-code)Questions
- Does MiMo-Code run?
- Yes. MiMo-Code runs. Argusic installed and launched it on a clean machine in 5 minutes, hitting 6 errors on the way, and recorded the session.
- How did Argusic test MiMo-Code?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit 849ca66cc8de. 2 attempts are recorded, and the full method is on the methodology page.
- What did it cost to test MiMo-Code?
- The run that produced this verdict cost $0.17: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does MiMo-Code take to install?
- 5.3 minutes in the run that decided this verdict, from a clean machine to a running state. That is one measured attempt, not an average.
- Does MiMo-Code need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing MiMo-Code?
- 6 things broke in the recorded run, and 6 were fixed without human help. Each one, and the time it cost, is listed on this page.
- How does MiMo-Code compare with the alternatives?
- Of the 46 ai projects Argusic has installed and timed, MiMo-Code was the 22nd fastest to reach a running state, and 37 of 46 reached one at all.
- Where is the evidence for MiMo-Code?
- All 2 recorded runs are on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
