GitHub’s Project Rubicon handles 5,000 concurrent AI agents, 7,200 pushes per second

Cointime update: GitHub published internal test results for Project Rubicon, a new Git storage architecture that supports 5,000 AI agents working concurrently on a single repository, handling 7,200 pushes per second to that repository with stable low-latency reads. The design, begun in May 2026, decouples storage from compute: Git objects sit in Azure Blob Storage, ref state is committed by an independently replicated Ref-CAS service using compare-and-swap, and compaction runs on separate background nodes. The architecture was unveiled at GitHub Universe and is in limited private preview, with wider rollout planned for early 2027.
