Symphony is OpenAI's open-source framework that turns project work into isolated, autonomous implementation runs. Instead of supervising coding agents line by line, teams assign tasks from project boards and Symphony dispatches agents to handle them independently. Each agent works in an isolated workspace, provides proof of work documentation including CI status and PR review feedback, and can automatically merge approved pull requests.
