Model Card

CoBuddy is a code generation model from Baidu, released through the Qianfan platform and optimized for coding tasks and AI agent workflows.

The model offers native support for both tool calling and reasoning, making it a strong fit for agentic use cases where the model needs to plan, invoke tools, and iterate. It provides a 131K token context window with up to 65K output tokens, giving it ample room for large codebases and extended generation.

CoBuddy is engineered for high inference throughput and low end-to-end latency. It's a solid choice for developers building code-centric agents or assistive coding tools who need responsive performance alongside structured tool use.
