GPT-4.1 Mini vs MiniMax M2.1
MiniMax M2.1 leads GPT-4.1 Mini on the Artificial Analysis Intelligence Index, 20.9 to 10.2, and MiniMax M2.1 costs 1.3x less per output token ($1.20 vs $1.60 per million). Updated October 22, 2026; 27 benchmarks have a result for both.
GPT-4.1 Mini or MiniMax M2.1: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick GPT-4.1 Mini for a larger context window (1.05M against 205K tokens) and work measured by LiveCodeBench (Vals AI) or LiveCodeBench (Artificial Analysis run), where it leads.
