On October 19, 2026, MiniMax officially launched M3.1 Flash. The company said the anonymously operated Space Bunny model was an early version. M3.1 Flash targets agentic tasks, software development, computer use and cybersecurity.

Key details from the release

MiniMax reports nearly three times faster online inference and a 70% reduction in overall usage cost for agentic tasks compared with its predecessor. Listed API prices are $0.15 per million input tokens, $0.60 per million output tokens and $0.015 per million cached input tokens. Performance and cost figures are the company’s own reported results.

Where it is available

MiniMax says the model is available through its API, M Plan and MiniMax Code, with model weights to follow later. The announcement emphasizes complex task execution, tool use and long sequences of work, reflecting a broader move from producing answers toward completing tasks.

Our perspective: cost a successfully completed task

When piloting an agent, include document preparation, tool calls, retries and human review in the calculation. A low token price is attractive, but completion reliability and business acceptance are more useful measures. Comparing a small set of representative workflows helps establish whether the model fits an existing process.
