# MiniMax M3.1 Flash

minimax, released 2026-10-19

**Verdict: conditional.** 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. Last verified 2026-10-20.

## Pricing

- Input: $0.15 / 1M tokens
- Output: $0.60 / 1M tokens
- Context: 1M context; cached input $0.015 / 1M

## Strengths

- 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
- 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
