GitHub Copilot's Project HydraFusion Promises Frontier Level Performance Through Multi-Model Routing
GitHub Copilot just shipped multi-model routing. Frontier performance. A fraction of the cost.
Why it matters
Project HydraFusion represents a shift in how coding AI handles complexity: instead of one model per task, it orchestrates multiple providers at runtime based on task difficulty. Practitioners get better code completion while cutting inference costs—a real lever for Copilot adoption and cost justification in enterprise.
