Composer 2 vs MiniMax M3

Pick MiniMax M3 if you want the stronger benchmark profile. Composer 2 only becomes the better choice if you want the stronger reasoning-first profile.

MiniMax M3 has the cleaner provisional overall profile here, landing at 76 versus 73. It is a real lead, but still close enough that category-level strengths matter more than the headline number.

MiniMax M3's sharpest advantage is in agentic, where it averages 71.9 against 61.7. The single biggest benchmark swing on the page is Terminal-Bench 2.0, 61.7% to 66%.

Composer 2 is also the more expensive model on tokens at $0.50 input / $2.50 output per 1M tokens, versus $0.30 input / $1.20 output per 1M tokens for MiniMax M3. That is roughly 2.1x on output cost alone. Composer 2 is the reasoning model in the pair, while MiniMax M3 is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use. MiniMax M3 gives you the larger context window at 1M, compared with 200K for Composer 2.
