GitHub has introduced Copilot Fusion, a new feature designed to automate model selection for developers by routing tasks across different AI models based on specified effort levels. This approach aims to optimize cost and speed, with claims that Fusion Max can outperform models like Claude Code on Opus 5.5 in coding benchmarks while using fewer resources. The system also incorporates a critique step where one model reviews another's output, and GitHub Enterprise is shifting to a credit-based access model for its AI features. AI
IMPACT Automates model selection for developers, shifting focus to task specification and potentially lowering costs for AI-powered coding tasks.
RANK_REASON This is a product update for a developer tool, not a core AI model release or research breakthrough.
