MiniMax M3.1 Flash is MiniMax’s new Flash model for agentic tasks, coding, computer use and cybersecurity. MiniMax says it is about 3x faster online and 70% cheaper for agentic tasks than its predecessor, with output at 200+ tokens per second. Pricing is $0.15 input and $0.60 output per 1M tokens. It’s on the MiniMax API, M Plan and MiniMax Code, and weights are promised later.

MiniMax M3.1 Flash is MiniMax’s next-generation Flash model, built for agentic tasks, coding, computer use and cybersecurity. MiniMax calls it a “generational leap” over its predecessor.

An early version ran anonymously as “Space Bunny”, and MiniMax says it processed over 200 trillion tokens before the official launch.

What’s new in M3.1 Flash:

  • About 3x faster online inference than its predecessor, with more aggressive sparsity improving inference efficiency

  • A 70% lower usage cost for agentic tasks

  • Output at 200+ tokens per second in everyday use, with a median of 170+

  • Stronger agentic, coding, computer use and cybersecurity performance

Some numbers:

  • DeepSWE v1.1: 73.7%

  • OSWorld V2: 61.7 and ALE: 29.6, which MiniMax says rank first among Chinese models

  • BankerToolBench: 76.2

  • CyberGym: 82%, assessed by MiniMax’s internal security experts

Pricing is flat at $0.15 per 1M input tokens, $0.60 per 1M output tokens and $0.015 per 1M cached input tokens.

You can use it through the MiniMax API, the M Plan subscription and the MiniMax Code desktop app. Good fit if you’re building coding or computer-use agents and want a fast, low-cost model.
