OpenAI Symphony
Also known as: OpenAI Symphony / Symphony / シンフォニー
OpenAI's 2026 open-source orchestration spec — integrates with ticket tools like Linear to auto-trigger agents and submit PRs.
Overview
Symphony standardises: Linear ticket created → Codex agent spawned → code implemented → PR opened. Humans only intervene at the PR review stage.
See OpenAI Symphony explainer. The open spec allows any agent runtime — not just Codex — to implement it.
