kimi-k3.1-pro

Kimi K3.1 Pro is the first model in the Kimi K3.1 series, built for complex tasks such as long-horizon coding, 3D creation, and financial research. It excels at fixing issues in real codebases, multi-step tool use, and end-to-end project building, and can also handle game engine scripting, 3D modeling, and interactive scene generation. The model natively supports vision understanding and accepts video input, making it suitable for analyzing and generating mixed text-and-image content. Its thinking mode is always on, with reasoning effort adjustable on demand, making it useful for agent scenarios that require multi-turn planning, external tool collaboration, and result verification. It has a context window of about 1 million tokens and can be used for large codebases, long documents, and cross-document verification. The model supports function calling and structured output, and can be used in automated workflows with strict constraints on response format.
