What is ChatDev?
ChatDev began as a multi-agent "virtual software company" in which agents such as a CEO, CTO and programmer design, code, test and document software together. That classic version (1.x) is maintained on its own branch.
ChatDev 2.0 (DevAll), released in January 2026, is a zero-code multi-agent orchestration platform: you define agents, workflows and tasks through configuration rather than code. The team's paper on multi-agent collaboration through evolving orchestration was accepted at NeurIPS 2025.
