OpenAI deploys Pando Git backend for monorepo scaling

OpenAI built and deployed Pando, a new Git repository backend designed to scale source control for agent-driven development. Pando achieves horizontally scalable writes and high read throughput by using a causal consistency model and reusing packfiles across fetches rather than generating unique ones for every client. In production, the system cut median push latency by nearly eighty percent and delivers close to a petabyte of Git data per day. Open article →
