ChatDev
A multi-agent orchestration platform that lets a user define agents, workflows and tasks through configuration rather than code, evolved from an earlier system that simulated a whole virtual software company.
ChatDev 2.0, also called DevAll, is a zero-code multi-agent platform: a user configures agents, workflows and tasks to orchestrate scenarios such as data visualization, 3D generation or deep research, without writing code for the orchestration itself. The earlier ChatDev 1.0, kept as a legacy branch, works as a simulated virtual software company, in which agents playing roles such as CEO, CTO and programmer take part in structured seminars to carry out an entire software development lifecycle: designing, coding, testing and documenting.
Related research from the same project explores alternative multi-agent collaboration structures, including a learnable central orchestrator that dynamically activates and sequences agents, and a directed-acyclic-graph topology (MacNet) that lets more than a thousand agents cooperate on a task without exceeding context limits, extending the approach beyond software development to tasks such as logical reasoning and data analysis.
