OpenAgents is an open-source platform designed to make advanced language agent capabilities accessible to everyday users, developers, and researchers. It features three main agents: the Data Agent for data analysis using Python and SQL, the Plugins Agent with access to over 200 daily-use API tools, and the Web Agent for autonomous web browsing. OpenAgents stands out for its user-friendly web interface, allowing non-technical users to interact with agents for tasks like data visualization, automated web browsing, and plugin integration, while also offering developers full-stack deployment flexibility and extensibility. The platform aims to bridge the gap between proof-of-concept language agents and real-world applications, supporting seamless local deployment and enabling robust evaluation of agent performance in practical scenarios
