GPT-4 vs MiniMax M2.1
MiniMax M2.1 leads GPT-4 on the Artificial Analysis Intelligence Index, 20.9 to 6.7, and MiniMax M2.1 costs 50.0x less per output token ($1.20 vs $60.00 per million). Updated October 22, 2026; 4 benchmarks have a result for both.
GPT-4 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 for work measured by AA Intelligence Index or GPQA Diamond (Artificial Analysis run), where it leads.
