The full picture

OpenAI built Pando, a Git-compatible backend for its monorepo, cutting push latency by approximately 80% and serving nearly a petabyte of Git data per day. The system was designed to handle increased load from both engineers and AI agents without changing existing Git workflows. OpenAI said the motivation was the scale of development that its Codex AI coding tool makes possible, which exceeded what standard Git can support.
