What is symphony?

An experimental framework by OpenAI that automates project implementation by spawning isolated AI agents to resolve tasks.

What does symphony do?

Symphony is an experimental research framework developed by OpenAI designed to fundamentally shift software development from writing code to managing autonomous AI workers. It actively monitors project management boards, such as Linear, and automatically spawns specific AI agents in completely isolated environments to implement requested tasks. The framework mandates that these agents generate comprehensive proof of work, including detailed CI status, complexity analysis, and illustrative walkthrough videos. Once the provided work is reviewed and fully accepted by a human manager, the system safely lands and merges the agent-generated code changes. It operates most effectively within codebases that have intentionally adopted structured harness engineering principles.

Who is symphony for?

Advanced software engineering teams and AI researchers exploring autonomous agent orchestration in trusted, specifically structured codebases.

• Autonomous Task Execution: Spawns isolated AI agents to independently handle and implement specific software engineering tickets.
• Project Board Monitoring: Integrates deeply with tools like Linear to automatically detect and process new work items.
• Proof of Work Generation: Requires agents to produce passing CI status and walkthrough videos for human review before merging.
• Automated Pull Requests: Safely manages the integration and merging of agent-generated code once approved by a human.
• Harness Engineering Focus: Designed to operate most effectively within codebases structured specifically around harness engineering principles.
