About

MiniMax M3.1 Flash (API ID MiniMax-M3.1-Flash) is MiniMax's M-series language model for agentic reasoning, tool use, coding, computer use, cybersecurity and long-context tasks. It has a 1,000,000-token context window, accepts text, image and video input, and always thinks before answering, with tunable thinking depth (effort: low, medium, high, xhigh, max; default max). Flat pay-as-you-go pricing is $0.15 / $0.60 / $0.015 per 1M input / output / cached-input tokens. It replaces MiniMax M3.1 Flash Preview. Model weights are promised later and are not on Hugging Face as of 2026-10-19.
