GitHub highlights Copilot Fusion and multi-agent Projects at Universe

At GitHub Universe, Satya Nadella said Copilot Fusion delivers “frontier-level quality,” is 40% faster and costs up to 77% less. He said Copilot Projects coordinates multiple agents across repositories and the unified Copilot harness is now in Foundry. Separately, another user claimed GitHub recorded 7.38 billion commits in September 2026, more than five times the year-earlier figure, and is moving to a multi-region Azure deployment due to finish in early 2027.
