GitHub Copilot adds HydraFusion Max option

Summary

GitHub updated HydraFusion, the Copilot feature that orchestrates multiple models into a single response, and introduced HydraFusion Max, a new option tuned for frontier capability on demanding tasks. The model pool now includes Claude Opus 5.5, GPT-6 Astra, GPT-6.1 Sol and GPT-6 Luna. Reasoning effort is now tailored to each stage, with medium effort for initial drafts and high effort for review, and the Critique workflow runs parallel critic models that inspect the workspace with tools. Both options remain in research preview across VS Code, the Copilot app and Copilot CLI.

Why it matters for our work

Coding agents are evolving from single models to orchestration that combines each model's strengths, letting developers delegate model choice to the tool and focus on verifying results. As model mixes and reasoning effort shift automatically, understanding the cost-quality balance matters more.
