Pando is meant to keep OpenAI's central code repository standing under the flood of agent work
The new system, Pando, keeps the standard Git protocol intact but lets each branch work independently and cuts push wait times by about 80 percent.
OpenAI has shared details of Pando, a home-built Git backend that runs the company's large central code repository. The trigger was the huge increase in changes from the coding agent Codex: by the third quarter of 2026 the number of commits was more than 14 times higher than in early 2024, GIGAZINE writes. From the end of 2025, pushes failed and merges were delayed, with reliability at times dropping below 90 percent.
Pando leaves the Git protocol and the ordinary Git client untouched, so developers and agents keep working the same way, Qodo explains. The system does give up repository-wide consistency and coordinates each branch separately, so pushes to different branches do not wait on each other. Median push latency fell by nearly 80 percent. Pando serves nearly a petabyte of Git data a day, with more than 57 terabytes in the busiest hour.
According to both sources, one engineer designed the core while agents built the system in ten weeks using Codex; GIGAZINE notes it is written in Rust. Pando has been in production since April 2026. OpenAI is not making the code openly available, but several fixes to the Git client are already in Git itself.
