An open-source framework utilizing large language models to automate the entire software development process through multi-agent collaboration.
ChatDev is an open-source framework that simulates a virtual software company, employing intelligent agents powered by large language models (LLMs) to automate the software development lifecycle. By adopting a waterfall model, ChatDev divides the process into distinct phases—designing, coding, testing, and documentation—with specialized agents collaborating in each phase. This approach enables the rapid and cost-effective generation of complete software applications, including source code, user manuals, and environmental dependencies. ChatDev's innovative use of multi-agent systems and natural language communication streamlines development workflows, reduces errors, and enhances efficiency.
