Everyone said Xiaomi's new open model "beats Claude". Here's the table the claim comes from, and how to read it.
The headline numbers
- Released: 22 Sep 2026, the same day Anthropic launched Claude Opus 5.5.
- Licence: MIT (open weights).
- Size: 1.02 trillion parameters in total, 42B active per token (sparse mixture of experts).
- Context: 1 million tokens.
The head-to-head, by our count of Xiaomi's own table
Against Claude Opus 5 (not the new 5.5), across the 14 tests where both models have a score:
| Result | Count | Which tests | |---|---|---| | MiMo wins | 3 | AutomationBench, Terminal Bench 2.1, MiMo VisualCoding | | Tie | 1 | Agents' Last Exam | | MiMo loses | 10 | the other 10 rows |
Key rows (MiMo-V2.6 Pro / Claude Opus 5 / GPT-5.6 Sol)
| Benchmark | MiMo Pro | Claude Opus 5 | GPT-5.6 Sol | |---|---|---|---| | Terminal Bench 2.1 | 89.9 | 89.1 | 88.8 | | AutomationBench v1.0.6 | 53.1 | 50.3 | 45.8 | | Agents' Last Exam | 31.6 | 31.6 | 30.8 | | DeepSWE v1.1 | 71.9 | 74.0 | 73.0 | | Terminal Bench 4.0 | 34.9 | 49.0 | 39.9 | | OSWorld-Verified | 82.0 | 83.4 | 83.0 | | MiMo Code Bench | 63.2 | 68.6 | 59.3 |
All of these are Xiaomi's own numbers, not independent tests.
How to read any "X beats Y" AI headline (use this every time)
- Find the table. It's on the model card or the release page, never in the headline.
- Check which version it was compared against. Here it was Opus 5, not the Opus 5.5 that shipped the same day.
- Count wins and losses, not the best row. One strong row makes a headline; the tally tells the truth.
- Note who ran the test. Company-run benchmarks are claims; independent ones (e.g. Artificial Analysis) are evidence.
