Moonshot AI releases Kimi K2, a 1T-parameter MoE model with agentic capabilities

from English

Moonshot AI has released Kimi K2, a state-of-the-art mixture-of-experts language model featuring 32 billion activated parameters and 1 trillion total parameters. The model is trained using the Muon optimizer and is specifically optimized for agentic intelligence, including tool use and autonomous problem-solving.

Kimi K2 achieves 65.8% pass@1 on SWE-bench Verified tests with bash/editor tools and 47.3% on Multilingual tests.
The release includes Kimi-K2-Base for fine-tuning and Kimi-K2-Instruct for general-purpose chat and agentic experiences.
Checkpoints are available in block-fp8 format under the Modified MIT License, with API access via platform.moonshot.ai.

The model is designed to provide strong performance on reasoning and coding tasks while offering robust tool-calling capabilities for developers building autonomous agents.
