GitHub launched Copilot Fusion for multi-model orchestration; agent-generated pull requests now exceed one-third of platform totals.

The Microsoft remarks summary reports the launch of GitHub Copilot Fusion for multi-model orchestration. It does not identify the supported models, pricing, availability tiers, or detailed orchestration behavior.

Agent-generated pull requests reportedly increased sixfold over the preceding six months. They now account for more than one-third of all pull requests on GitHub, according to the summary.

The reported share concerns pull requests, not the share of all code written, accepted changes, or deployed software. The supplied source contains no merge-rate, code-quality, security, or developer-productivity measurements.
