CogAgent is a research-oriented, open-source Python library designed to streamline the development of AI agents. It provides core modules for memory management, planning and reasoning, tool and API integration, and chain-of-thought execution. With its highly modular architecture, users can define custom tools, memory stores, and agent policies to create conversational chatbots, autonomous task planners, and workflow automation scripts. CogAgent supports integration with popular LLMs such as OpenAI GPT and Meta LLaMA, allowing researchers and developers to experiment, extend, and scale their intelligent agents for a variety of real-world applications.
