KimiK2

KimiK2 is Moonshot AI’s flagship 1-trillion-parameter Mixture-of-Experts (MoE) LLM, engineered for state-of-the-art agentic intelligence and autonomous task execution.

KimiK2 is a powerful open-source model: a 1-trillion-parameter MoE architecture with only 32 billion active parameters per token, ensuring GPT-4-class performance with superior efficiency. This model is meticulously optimized for agentic workflows, meaning it doesn't just answer questions—it acts, autonomously executing complex, multi-step tasks. Key technical specifications include a massive 128,000-token context window and SOTA benchmark results, notably achieving 65.8% on SWE-bench Verified for autonomous coding. Developers access KimiK2 via an OpenAI-compatible API for integration into custom, high-performance AI applications.
