   MiniMax releases M3.1 Flash, reveals Space Bunny was an early version

   MiniMax announced M3.1 Flash on October 19 and confirmed that Space Bunny, the stealth model that had topped OpenRouter usage, was an early version of it. The API is priced at $0.15 per million input tokens, $0.60 per million output tokens and $0.015 for cached reads, with a 1M-token context, and MiniMax plans to publish open weights on October 23;社区 and Wccftech describe a 428B-total/23B-active MoE, though another post says the parameter count was not disclosed. The Decoder, citing Artificial Analysis, reports a score of 42 on the Intelligence Index — 13 points above M3 at less than half the cost per task — but also a 93% hallucination rate, while Chinese outlet 智东西 reports agentic benchmark results close to DeepSeek V4.1 Flash based largely on MiniMax's own numbers; reports conflict on some benchmark figures.
