OpenAI releases Symphony, an open-source spec for agent orchestration that turns a project-management board like Linear into a control plane for coding agents
Six months ago, while working on an internal productivity tool, our team made a controversial (at the time) decision: we'd build our repo with no human-written code.

📣 What if every open issue had a Codex agent? That's the idea behind Symphony, an open-source agent orchestrator for Codex that turns task trackers into always-on systems for agentic work, letting humans focus on review and direction. [video]

Engineers at OpenAI experience the same problem as everyone else — we can supervise about 3-5 coding agents. After that productivity drops. Codex is smart, but our attention is limited. So we built (and open sourced!) Symphony to remove that ceiling. Here's how it works:

We quietly launched the Symphony repo on Github last month, and it's already accumulated 15.5k stars! Excited to share this post that dives into it even deeper: a library that lets you use Codex to orchestrate work normally done by teams of engineers. https://openai.com/...

Symphony is amazing. Best agent orchestrator I've used. It's open-source and you can use it with your ChatGPT sub. Only downside I found: it's *VERY* token hungry. Closed 30 Linear issues with Symphony + Codex in a week and it was the closest I came to my weekly Codex limit.

Symphony: a minimal orchestration layer for Codex It connects issue trackers like Linear to coding agents, so each task can spin up its own Codex session In a nutshell: open issue → assign agent → generate PR → human review https://openai.com/...

Learning how to use coding agents effectively is the most interesting engineering problem in the world right now. The solution @alex_frantic came up with for our team is Symphony. I think Symphony has a few really interesting ideas embedded in it: 1. The approach itself.

We have reached a moment where instead of releasing software you simply release the detailed spec for software and tell people to prompt their agent to build it themselves — From the README of OpenAI's new Symphony orchestrator: github.com/openai/symph... [image]

free idea for someone: verifiable build pipelines that use specific models to “compile” specifications like github.com/openai/symph... into code, then compile that code into binaries. — I care to audit the spec, I care not to audit each line of code, and I just want to know bin…
