About This AI

MiniMax M2.1 is an enhanced large language model from MiniMax, released on December 23, 2025, optimized for multi-language programming, agentic workflows, and office automation.

With a sparse MoE architecture (230B total parameters, 10B active per token), it delivers high performance with low latency, reduced token usage, and exceptional cost-efficiency.

It excels in Rust, Java, Golang, C++, Kotlin, Objective-C, TypeScript, JavaScript, and more, supporting native Android/iOS development, Web/App design, 3D rendering, interactive simulations, and full-stack scenarios.

The model features improved composite instruction following, concise responses, faster speed, and strong generalization across agent frameworks like Claude Code, Droid, Cline, Kilo Code, Roo Code, and BlackBox.

It demonstrates outstanding results on SWE-bench Verified (multilingual), VIBE benchmark (88.6 aggregate, with high Web/Android scores), and long-horizon tool use.

MiniMax M2.1 supports text, speech, video, and music multimodal integration, enabling digital employee capabilities for end-to-end office tasks (admin, data science, finance, HR, software dev).

Available open-source on Hugging Face for local deployment (via SGLang, vLLM, Transformers), with API access on MiniMax platform and free/limited-time access to MiniMax Agent chat interface.

Pricing is highly competitive at $0.30 per million input tokens and $1.20 per million output tokens, making it accessible for developers and enterprises building autonomous applications.
