What is Kimi K3?

Kimi K3 is Moonshot AI's 2.8-trillion-parameter flagship open-weight model. It features native visual understanding, a 1-million-token context window, and the Kimi Delta Attention (KDA) architecture. It is the first open-source model in the 3-trillion-parameter class, with full weights released on Hugging Face under a Modified MIT license.

Core Capabilities

• Massive scale: 2.8T total parameters with Mixture-of-Experts architecture.
• Long context: 1M-token context window for long-document and codebase analysis.
• Native multimodality: understands images, video, and text in a unified architecture.
• Kimi Delta Attention (KDA): improves efficiency on very long sequences.
• Open weights: full model weights available for research and local deployment.
