MiniMax M3
MiniMax M3
Open weights tuned for software work, and the fastest decoding of anything in its class.
Updated
The read
M3 is a coding-first open model with an attention design that decodes dramatically faster than a conventional transformer of the same size, which is what makes it usable inside an agent loop rather than just on a benchmark. It sits near the top of verified software engineering scores while costing a fraction of the closed models around it. The licence is a community licence with commercial conditions, so read it before shipping.
Where it shines
- Decodes far faster than comparable open models
- Near the top of verified software engineering benchmarks
- Million-token context, which coding agents genuinely use
Worth knowing first
- Community licence carries commercial restrictions
- Weaker outside code and agent work than its headline scores suggest
Index score
84.5
Provisional. This score is read from the product's public capability, not from the one-prompt rebuild the fully reviewed entries went through, so treat it as a placing rather than a verdict.
