OpenAI has introduced Pando , a new Git backend that now serves all development in its monorepo. The OpenAI Pando Git backend keeps the standard Git client and protocol. Engineers and Codex agents still run git push and git fetch as before. Only the server changed. OpenAI team reports median push latency fell nearly 80%. Pando now delivers nearly a petabyte of Git data per day. TL;DR Scale: Nearly 1 PB of Git data per day; peak above 57 TB in 1 hour. Runs on: Commodity hardware; standard cloud VMs saturate 10 Gbps links on clone and fetch. Performance: Thousands of concurrent pushers without degradation, per OpenAI’s own testing. Best: Median push latency down nearly 80% (about 5x). Worst: Not open source; repeat branch pushes resend non-trunk history (p99 pack under 3 MiB). What is OpenAI Pando? Pando is a Git-compatible server backend from OpenAI that scales concurrent pushes and fetches for a monorepo. It was written in Rust and reached production in 10 weeks. One engineer designed the core and teams of Codex agents implemented it. It has served production traffic since April 2026. Why did OpenAI need a new Git backend? Codex multiplied parallel work. …
