Xiaomi’s AI team says its MiMo-V2.6-Pro model leads the open-weight field on FrontierCode 1.1 at 45%. The claim builds on a leaderboard launched by Artificial Analysis a day earlier.
Here is what the benchmark measures and how to read the number.

Xiaomi MiMo-V2.6-Pro: Key Details
| Point | Detail |
|---|---|
| Model | MiMo-V2.6-Pro (Xiaomi) |
| Score | 45% on FrontierCode 1.1 |
| Claim | Leads the open-weight field |
| Benchmark creator | Cognition |
| Leaderboard | Artificial Analysis, launched 12 October |
What FrontierCode Tests
Artificial Analysis described FrontierCode 1.1 as a private evaluation from Cognition that tests models on completing coding tasks in a way that would actually get merged by maintainers of real-world repositories. Cognition announced FrontierCode in June 2026 and has since updated it.
Because the tasks are private, models cannot easily train on them, which gives the score more weight than public benchmarks that can leak into training data.
What the Score Means
A score of 45% does not mean the model writes correct code 45% of the time in general. It means that on this set of tasks, 45% of its answers met the merge standard. The claim is limited to open-weight models, so closed models may score higher.
Open-weight means the weights can be downloaded and run by others, which matters for developers who want to self-host. Learn more about Xiaomi and open-weight models.
Why Xiaomi Is in This Race
Smartphone makers have started to build their own models for on-device and cloud use. A strong coding result is a useful credential for Xiaomi’s AI group. See our AI coverage for related launches.
Developers should test MiMo on their own tasks before committing, since a leaderboard lead on one benchmark can disappear on another.
How to Verify the Claim
The simplest check is the Artificial Analysis leaderboard itself, which lists the model scores side by side. Compare MiMo with other open-weight entries and with closed models to see where it sits overall.
Also look at pricing and hosting options, since an open-weight model is only as useful as the infrastructure that runs it.
What Is Not Confirmed
- The scores of closed models on the same benchmark in our sources.
- Model size and licence terms.
- Where developers can download or run the model.
- Independent re-runs of the benchmark.
Quick Answers
What did MiMo-V2.6-Pro score?
45% on FrontierCode 1.1, per Xiaomi MiMo.
Who made the benchmark?
Cognition, with the leaderboard run by Artificial Analysis.
Is it the best AI coding model overall?
No. The claim is for open-weight models only.

Open-Weight Does Not Mean Cheap to Run
Large open-weight models need serious hardware. Teams often use hosted providers or quantised versions, which can change quality. A benchmark score tells you the best case, not what you get on a cheaper setup.
Compare MiMo with other open models on your own languages and frameworks, and watch for updates, since the open-weight field changes monthly and a lead at 45% can be passed quickly.
Bottom Line
MiMo-V2.6-Pro’s lead is a good sign for open-weight coding models, and a credible result for Xiaomi’s AI team. The claim is about one benchmark, so use it as a starting point for your own tests.
Check the licence, hardware needs and community feedback before building anything on top of it.
