GitHub Copilot's Experimental HydraFusion Multi-Model Orchestrator Expands to VS Code and the Copilot App

GitHub expanded its experimental HydraFusion feature from Copilot CLI-only access to VS Code and the GitHub Copilot app, adding real-time progress notifications and clearer status indicators for long-running tasks.

Details

• What HydraFusion does: treats workflow selection as an optimization problem, choosing between having one model solve a task directly, using an efficient model that escalates to a stronger one when needed, or running a critique pattern where independent reviewers suggest improvements
• Vs. Auto: Auto picks which single model handles each request, while HydraFusion selects a workflow and coordinates multiple models within a single turn
• What’s new: expansion beyond Copilot CLI to VS Code and the GitHub Copilot app, plus enhanced transparency through real-time progress notifications and status indicators during extended tasks
• Availability: experimental feature available to Copilot Pro, Pro+, Business, and Enterprise subscribers

What happened next

HydraFusion was first previewed as a Copilot CLI-only experiment in GitHub’s September 7 weekly release notes; this expansion to VS Code and the Copilot app brings multi-model orchestration to GitHub’s primary developer surfaces for the first time, alongside the same week’s rollout of GPT-6.1 Sol.
