About

MiniMax M3.1 Flash Preview (API id MiniMax-M3.1-Flash-Preview) is MiniMax's faster/lighter M3-series multimodal coding model announced for MiniMax Code on 2026-09-27 and made live on Token Plan the same day. First-party docs: 1,000,000-token context; text+image+video inputs to text; agentic reasoning, tool use, and coding; thinking always on with tunable effort low|medium|high|xhigh|max (default max; cannot disable — 400 'requires adaptive thinking'). Availability for now is Token Plan + MiniMax Code only — NOT on pay-as-you-go (paygo price table lists M3/M2.x only; no M3.1 Flash $/MTok row). No public Hugging Face weights/model card for the Flash Preview SKU.
