MiniMax-M2.1

Evaluations are finished for MiniMax-M2.1.

• It does well among open-weight models on coding tasks, ranking among the top 5 performers in SWE-bench Verified, Terminal-Bench and Live Code Bench.
• It also ties for first place among open-weight models on our Case Law v2 benchmark, and is second among open-weight models on our Finance Agent benchmark.
• The model also offers these capabilities at a relatively low cost and latency compared with its peers.

While there remains significant room for improvement, it is a strong open-weight release from MiniMax AI, and we look forward to continued improvements on all our benchmarks.

NOTE: The model was tested with temperature=1 and top_p=0.95, via the Anthropic-compatible MiniMax API endpoint.

MiniMax-M2.1 ranks #2 among open-weight models on our Vals Index, but offers competitive performance with lower latency and cost compared to the #1 ranked open-weight model, GLM 4.7.

• It is #12 on the overall leaderboard, behind models from the likes of OpenAI, Gemini, and Anthropic.
• It ranks in the top 5 open-weight performers in all the benchmarks in our Vals Index.

The model was tested with temperature=1 and top_p=0.95, via the Anthropic-compatible MiniMax API endpoint.

Congratulations to MiniMax for a strong open-weight release! Results on the full suite of benchmarks will be released soon!
