About OpenBMB/ChatDev
ChatDev is an open-source project that uses multiple LLM-based agents working together to produce software and other outputs. Version 2.0, called DevAll, allows users to define agents, workflows, and tasks through configuration without writing code, with listed uses including data visualization, 3D generation, and deep research.
Version 1.0 works as a virtual software company with agents taking roles such as CEO, CTO, and Programmer to handle designing, coding, testing, and documenting. That version is maintained on a separate branch.
