MiniMax releases M3.1 Flash with stronger reasoning and lower task costs
MiniMax released M3.1 Flash, a reasoning model scoring 42 on the Artificial Analysis Intelligence Index, up from M3’s 29, at less than half the cost per task. It supports text and images with up to one million tokens of context; API pricing is $0.15 per million input tokens and $0.60 per million output tokens. Artificial Analysis reports a 93 percent hallucination rate because it answers rather than declines uncertain questions; open weights are planned for October 23.

Why it matters
The comparison shows how fewer output tokens can reduce task costs even when benchmark leadership is mixed, with MiniMax and Deepseek each leading on different measures.
