Open-Source Multi-Model Agent Framework CowAgent: Task Planning, Tool Calling & Memory Evolution

CowAgent is an open-source super AI assistant and agent harness derived from the chatgpt-on-wechat project. It supports multiple models and channels (WeChat, Telegram, etc.), enabling task step planning, tool and skill invocation, and self-evolution via memory and knowledge base. The project is lightweight with one-command installation, making it extremely accessible for Python developers. It has 45801 stars on GitHub and adds about 123 stars daily, reflecting active development. For individual developers or small teams wanting to experiment with agents quickly, CowAgent can directly replace existing chatbot code without building a RAG or tool chain from scratch. Developers using Claude API can leverage its multi-model feature to switch backends within one framework. The project is also ideal for LLM enthusiasts to learn agent architecture design.
