GitHub launches Copilot Fusion as AI agents open 40% of code requests

GitHub has launched a new tool called Copilot Fusion, built around AI agents. The company says agents now start about 40% of pull requests. A pull request is a proposed change to a piece of software. So a large share of those changes now begin with an AI, not a person.

What changed

GitHub is a site where developers store and work on code. Copilot is its family of AI helpers. Copilot Fusion is the newest piece, and it centers on agents. An agent is an AI program that can take on a task and carry it out with limited hand-holding, such as drafting a change to code.

Who it affects

Developers feel it first. Any business that pays for custom software, or relies on apps built by outside teams, is next in line. If AI helps teams propose changes faster, updates and fixes could arrive sooner.

The safeguard

Developers still review changes before they go live. That human sign-off is the main check on AI-written code. The 40% figure describes who starts a change, not who approves it.

What is not known yet

The material available does not say how Copilot Fusion is priced, who can use it now, or how GitHub measured the 40% figure. It also does not explain how reviews will work as the volume of AI-started changes grows.

• Ask your developers how AI-written code gets checked.
• Ask who signs off on changes before release.
• Ask whether faster updates are expected.
