The HKU team has open-sourced the Agent framework OpenAgents, which supports over 200 plugins and aims to facilitate the construction of proof-of-concept language agents, while considering the design for non-professional users' access and application. OpenAgents currently implements three types of agents: Data Agent, Plugin Agent, and Web Agent, and has performed excellently in the CG-Eval evaluation. The core features of the framework include providing three practical language agents and supporting both web UI and local setup for using and hosting agents.
