MiniMax officially released M3.1 Flash on October 19 and says model weights will be released later. This exact API checkpoint is closed. The announcement describes increased sparsity but does not disclose parameter counts or a sufficient exact architecture specification; no unsupported numeric estimate is assigned. Space Bunny was an early version, not proof of identical checkpoint weights. Retain its historical measurements separately. The exact free route declares mandatory low, medium, high, xhigh and max reasoning efforts. Its MiniMax endpoint reports training=false with prompt retention; use existing OpenRouter account guardrails.
