GitHub debuts Copilot Fusion, a new model selection & orchestration system that beats Claude Code for half the API cost
GitHub introduced Copilot Fusion at GitHub Universe, combining project HydraFusion's runtime orchestration with Copilot Auto Model Selection. The system intelligently routes coding tasks to appropriate models for reasoning, code generation, debugging, and tool use. GitHub reports Fusion Max achieves comparable performance to Claude Code at roughly 50% of the API cost and 40% faster execution, allowing developers to delegate model selection decisions while retaining control over work direction.
Key points
- Copilot Fusion automates model selection and orchestration for development tasks
- Achieves Claude Code parity at ~50% API cost and 40% faster performance
- Generally available now; announced at GitHub Universe in San Francisco
