Today, MiniMax officially rolled out M3.1 Flash, the next-generation Flash model. Its early version, codenamed Space Bunny, processed more than 200 trillion tokens while operating anonymously. The model delivers a generational leap in agentic tasks, coding, computer use and cybersecurity, while making online inference nearly three times faster and cutting usage costs by 70%.
M3.1 Flash reaches the level of leading models across a broad range of benchmarks. On Automation Bench-AA, it ranks among the top performers and can complete real enterprise workflows across SaaS systems, from sales and marketing to finance and HR. It scores 76.2 on Banker Tool Bench, which tests multi-step planning, document consistency and financial compliance. On Deep SWE v1.1, it achieves 73.7%, placing it alongside top models in complex software engineering.
In computer use, the model scores 61.7 on OSWorld V2 and 29.6 on Agents' Last Exam, ranking first among Chinese models on both benchmarks. In cybersecurity, it achieves a strong score of 82% on Cyber Gym, with strong performance in code auditing, vulnerability patching, penetration testing, malware analysis and reverse engineering. Output speeds can reach 200+ tokens per second, with median speeds consistently above 170.
Pricing is flat at $0.15 per million input tokens, $0.60 per million output tokens and $0.015 per million cached input tokens. The model is available through the MiniMax API, M Plan and MiniMax Code, with model weights to follow later. MiniMax says Flash reflects its ongoing effort to balance efficiency and capability, and that the more intelligence-focused Pro model will arrive later.
