OpenAI open-sources Symphony for agent orchestration

2026-04-29 · openai

OpenAI published Symphony, a written spec for coordinating coding agents around tasks instead of chat sessions. The goal is to reduce context switching and let issue trackers drive agent work end to end.

Key Features or Updates

Symphony treats a project board like Linear as the control plane, where open tasks are picked up by agents and run continuously. OpenAI says this approach helped some teams land 500% more pull requests in the first three weeks.

Impact on Developers

The big shift is moving from supervising individual sessions to managing work as a task graph. That makes larger engineering efforts easier to parallelize and keeps humans focused on review and direction.

How to use it

If you already run agentic workflows, map tasks, dependencies, and review checkpoints into your tracker. Use Symphony as a spec for building an always-on agent pipeline instead of a one-off chat loop.
