MiniMax M3.1-Flash-Preview: The Quiet Launch, Stealth Benchmarking, and the New Speed Tier for Everyday Coding
On September 27, 2026, MiniMax quietly launched M3.1-Flash-Preview inside its MiniMax Code agent tool — no model card, no benchmarks, no public pricing. A stealth benchmark via OpenRouter's 'Space Bunny Alpha' preceded the official launch by four days. The model features a 1M-token context, forced reasoning with six effort levels, and dramatically faster inference than the M3 flagship.
