Description
Kimi K3 is an open-weight, native multimodal agentic model developed by Moonshot AI, representing their most capable model to date. With 2.8 trillion parameters, Kimi K3 is built on Kimi Delta Attention (KDA) and Attention Residuals (AttnRes), featuring native vision capabilities and a remarkable 1-million-token context window. This model is recognized as the world's first open 3T-class model, specifically designed to excel in frontier intelligence applications, including long-horizon coding, knowledge work, and reasoning.
The architecture of Kimi K3 incorporates a mixture-of-experts (MoE) framework that activates 16 out of 896 experts, achieving approximately 2.5 times improvement in scaling efficiency compared to its predecessor, Kimi K2. This allows Kimi K3 to operate with minimal human oversight, sustaining long engineering sessions while navigating massive repositories and orchestrating terminal tools. Its capabilities extend to GPU kernel optimization, compiler development, and even complex tasks like vision-in-the-loop game development, CAD, and chip design.
Kimi K3 also advances end-to-end knowledge work, producing deep research with interactive visualizations, widgets, dashboards, and motion design. Its native multimodal architecture enables it to understand and process text, images, and video within the same model, enhancing its versatility and application range.
The model's weights are released under the Kimi K3 License, promoting open access for research, deployment, and further innovation. Kimi K3 is designed to be integrated easily via API, with support for various inference engines, making it accessible for developers and researchers alike. The deployment of Kimi K3 is recommended on platforms like vLLM, SGLang, and TokenSpeed, ensuring broad compatibility and performance optimization.
In summary, Kimi K3 is a groundbreaking AI model that combines advanced architecture with extensive capabilities, making it a valuable tool for professionals in coding, knowledge work, and research.
