MiniMax M3.1 Flash is a next-generation LLM optimized for agentic tasks, coding, computer use, and cybersecurity, offering a major jump in capability while slashing inference cost. An early version nicknamed Space Bunny processed over 200 trillion tokens. Benchmarks show top-tier performance: AutomationBench-AA for complex enterprise workflows, BankerToolBench 76.2 for multi-step planning and compliance tasks, DeepSWE 73.7% for complex software development and testing, OSWorld V2 61.7 and Agents’ Last Exam (ALE) 29.6 for real-world computer operation and cross-application task execution, and CyberGym 82% for vulnerability discovery and validation. Internal security evaluations highlight strong results in code auditing, patching, penetration testing, malware analysis, and reverse engineering. The model excels at long, chained tool calls and completing end-to-end SaaS workflows across sales, marketing, operations, customer service, finance, and HR.
Inference efficiency is improved via aggressive sparsity, delivering everyday output speeds above 200 tokens per second and median P50 speeds over 170 TPS. Overall usage cost for agentic tasks is reduced by 70% versus its predecessor, with flat pricing per 1M tokens at $0.15 input, $0.60 output, and $0.015 cached input. M3.1 Flash is available through the MiniMax API, M Plan, and MiniMax Code (desktop client); model weights and a higher-capability “Pro” variant are slated for later release.
