MiniMax M1 vs MiniMax M2.5
MiniMax M2.5 leads MiniMax M1 on the Artificial Analysis Intelligence Index, 22.8 to 11.7, and MiniMax M2.5 costs 1.8x less per output token ($1.20 vs $2.20 per million). Updated October 23, 2026; 29 benchmarks have a result for both.
MiniMax M1 or MiniMax M2.5: which to pick
Only MiniMax M2.5 has a coding score, 37.2 on the Vibe Coding Index; MiniMax M1 has none, so the two cannot be ranked on coding.
Pick MiniMax M1 for a larger context window (1M against 205K tokens) and work measured by LMArena Text: Japanese or LMArena Text: Korean, where it leads.
