# GitHub turns Copilot into an agent orchestrator across projects and models

**Copilot Fusion is generally available and cross-repository Projects enters public preview; GitHub says Fusion used about half the API cost per task in a benchmark.**

## Why it matters

GitHub is using its code-hosting position to make model routing and multi-agent execution part of the same workflow as repositories and pull requests. Adoption will depend on whether agents can complete cross-repository work reliably, with review and costs clear to the developer.

[Satya Nadella (@satyanadella)](https://x.com/satyanadella) used GitHub Universe on October 28th to present GitHub Copilot as an agent orchestration system: one that selects models, runs agents across repositories and returns work for developers to review. The [Microsoft chairman and CEO's post](https://x.com/satyanadella/status/2115490856685990244) highlighted GitHub Copilot Fusion, Copilot Projects and the availability of GitHub's Copilot harness in Microsoft Foundry.
