MiniMax M3.1 Flash

Today, we officially roll out MiniMax M3.1 Flash.

Space Bunny 🐰, which processed more than 200 trillion tokens while operating anonymously, was an early version of MiniMax M3.1 Flash.

As a next-generation Flash model, M3.1 Flash delivers a generational leap in agentic tasks, coding, Computer Use and cybersecurity, while making online inference nearly three times faster and reducing usage costs by 70%.

M3.1 Flash improves across a broad range of benchmarks, reaching the level of leading models in complex agentic tasks (cowork), computer use, software development (coding), and cybersecurity.

We have further optimized M3.1 Flash’s inference efficiency through more aggressive sparsity. In everyday use, output speeds can reach 200+ TPS (tokens per second), with median (P50) speeds consistently reaching 170+ TPS.

For agentic tasks, the model’s overall usage cost is 70% lower than its predecessor.

Flat pricing per 1M tokens: $0.15 input · $0.60 output · $0.015 cached input.

Across three benchmarks—Automation-Bench for complex agentic task execution, DeepSWE for real-world coding, and Agents’ Last Exam (ALE) for computer use in real-world tasks with economic value—M3.1 Flash delivers performance on par with top models at a very low task cost, setting a highly competitive new standard for performance and cost.

M3.1 Flash is now available through the MiniMax API, M Plan, and MiniMax Code. Model weights will be released later.

Flash represents our ongoing exploration of the balance between efficiency and capability. Pro, which pushes the boundaries of intelligence, will also arrive later.
