GitHub Copilot HydraFusion adds Max option, refreshed model pool, and smarter Cascade/Critique
HydraFusion’s research preview now draws from Claude Opus 5.5, GPT-6 Astra, GPT-6.1 Sol, and GPT-6 Luna, tailors reasoning effort per stage, and upgrades Cascade with a judge/repair step and Critique with parallel tool-using critics. New HydraFusion Max targets harder tasks; both options stay in preview on Copilot Pro through Enterprise in VS Code, the Copilot app, and CLI.
