MiniMax M3.1 Flash
minimax · Released Oct 2026
MiniMax M3.1 Flash is a 1M-context multimodal coding and agent model at $0.15 input and $0.60 output per 1M tokens, and MiniMax says its agentic usage cost is 70% lower than its predecessor's. The deciding caveat is evidence: the launch post's scores are MiniMax's own, it names no comparison model, and the weights are promised only for later. Worth a trial for cost-sensitive agent and computer-use workloads, not yet for anyone who needs self-hosting or independent scores.
Is it right for you?
Good for
- Agent and computer-use work on a budget: $0.15 / $0.60 per 1M tokens with cached input at $0.015
- Long-context coding and tool use: 1M context window, tunable thinking depth and interleaved thinking with tool calls
- Fast agent loops: MiniMax reports output speeds of 200+ tokens per second and a median above 170
Not good for
- Self-hosting today: the post says 'Model weights will be released later', with no date
- Decisions that need independent benchmark evidence: the scores in the launch post are MiniMax's own, and the pages we read name no third-party run
How it performs by task

Documented as an agentic model with interleaved thinking and tool calling over Anthropic and OpenAI SDKs; MiniMax reports it ranks among the top performers on AutomationBench-AA (vendor claim)
Computer use
MiniMax reports 61.7 on OSWorld V2 and 29.6 on Agents' Last Exam, first among Chinese models on both (vendor claim)
Software engineering
MiniMax reports 73.7% on DeepSWE v1.1 (vendor claim, comparison models unnamed)
