GitHub Introduces Project HydraFusion: Runtime Multi-Model Orchestration That Builds a Workflow Per Coding Task in Copilot CLI
GitHub's new multi-model orchestration in Copilot CLI dynamically chooses which AI workflow to run per task—not just picking one model.
Why it matters
Project HydraFusion treats model selection as a runtime optimization problem, routing coding tasks through Single, Cascade (with quality gates), or Critique patterns. This is a meaningful shift in how dev tools handle model uncertainty—practitioners will see real implications for latency, cost, and code quality in their IDE workflows.
The key facts

Publisher excerpt: We look at Project HydraFusion, GitHub's research preview that treats workflow selection as an optimization problem rather than a model picker. We break down the three execution patterns it routes between — Single, Cascade with a quality gate, and Critique with a read-only cross-family reviewer.…
