OpenAI's engineering blog details Pando, its in-house source-control system that now delivers nearly a petabyte of Git data per day. Built for concurrent pushes to many branches and maximal read throughput, Pando retains full Git protocol/client compatibility so engineers and coding agents could adopt it seamlessly. In production it cut median push latency by nearly 5x. The post covers why OpenAI built a new system, why Git compatibility mattered, and how Pando compares with common approaches to scaling Git.
