OpenAI unveils Pando, a Git backend built for the agent era

Summary

OpenAI says surging parallel work from Codex agents pushed its monorepo's Git servers to the breaking point, with reliability at times dropping below 90%, so it built a new backend called Pando and moved all development onto it. Pando lets pushes to different branches proceed in parallel and serves reads from shared caches. By the company's own account, median push latency fell nearly fivefold and the system now serves nearly a petabyte of Git data per day. Git protocol and client compatibility were preserved so engineers and agents keep their existing workflows, and OpenAI plans to contribute improvements upstream.

Why it matters for our work

A real-world case of source control itself becoming the bottleneck as agent counts grow. Keeping one shared tool, Git, while swapping the infrastructure underneath shows how human-agent collaboration can scale without forcing new workflows on people.
