MiniMax M2.1
Lightweight SOTA reasoning for production agentic systems on Together AI.
About model
Most Efficient SOTA Performance:
MiniMax M2.1 is a breakthrough 10B activated parameter model that delivers frontier-level performance while remaining the most cost-effective SOTA model in the open-source community. With advanced interleaved thinking, multilingual coding excellence, and enhanced scaffolding for popular agent frameworks, M2.1 is engineered for production workflows requiring both capability and efficiency.
Dedicated Deployment:
Available on on-demand dedicated and monthly reserved capacity on Together AI, ensuring consistent performance for complex coding, agent workflows, and creative applications at production scale.
Model card
Multilingual Coding Excellence:
• Significant performance gains across Rust, Java, Golang, C++, Kotlin, Objective-C, TypeScript, and JavaScript
• Web3 dominance: Special optimization for blockchain and decentralized protocols
• 49.4% on Multi-SWE-Bench (surpassing Claude 3.5 Sonnet and Gemini 1.5 Pro)
• Advanced code review with sophisticated performance optimization and structural analysis
Optimized for "Vibe" AppDev & Native Mobile:
• Enhanced web aesthetics for better UI/UX generation and scientific scenario simulations
• Significantly boosted native Android and iOS development capabilities
• Bridges gap between aesthetic design and technical implementation
Advanced Interleaved Thinking:
