OpenAI launches self-developed Git backend Pando
Understand this story
OpenAI has launched its self-developed Git backend Pando, which now carries all development traffic for its monorepo. OpenAI says median push latency has dropped by nearly 80%, with nearly 1 PB of Git data transferred daily. Pando has handled production traffic since April 2026, but it is not an open-source project; the OpenAI team says it is exploring ways to share the technology. The performance figures above are self-reported by OpenAI and have not yet been verified by independent benchmarks.

- MarkTechPostOpenAI Introduces Pando: A Git Backend That Cuts Median Push Latency ~80%
OpenAI introduced Pando, a Rust-written Git-compatible server backend now serving all development in its monorepo, which keeps the standard Git client and protocol while reporting median push latency down nearly 80% and nearly 1 PB of Git data per day. Pando uses per-branch causal consistency instead of repository-wide ordering, stores each pushed pack as an immutable blob with ref versions in a metadata store, and serves fetches via packfile-uri download links through a regional cache called Express with hit rates above 99%. It has served production traffic since April 2026, is not open source, and all performance figures are self-reported by OpenAI.
