GPT-5.4 vs MiniMax M2
GPT-5.4 leads MiniMax M2 on the Artificial Analysis Intelligence Index, 39.0 to 18.6, and MiniMax M2 costs 14.7x less per output token ($1.02 vs $15.00 per million). Updated October 22, 2026; 45 benchmarks have a result for both.
GPT-5.4 or MiniMax M2: which to pick
Only GPT-5.4 has a coding score, 64.4 on the Vibe Coding Index; MiniMax M2 has none, so the two cannot be ranked on coding.
Pick MiniMax M2 for output tokens 14.7x cheaper ($1.02 vs $15.00 per million) and a lower cost per solved task ($0.702 against $1.02).
