Yes, GitHub claims up to 67% lower estimated cost versus Claude Opus 5 in one benchmark. But the real shift is architectural: Copilot now orchestrates multiple AI models within a single coding task, dynamically selecting from three execution strategies. This is not a model upgrade. It is Copilot becoming a workflow engine. Three Patterns, One Routing Decision HydraFusion’s core mechanic is choosing — at runtime, per task — which of three execution patterns to apply: Single: One model […]\n\nThe post", "url": "https://wpnews.pro/news/github-hydrafusion-copilot-now-routes-workflows-not-models", "canonical_source": "https://byteiota.com/github-hydrafusion-copilot-now-routes-workflows-not-models/", "published_at": "2026-09-08 12:07:29+00:00", "updated_at": "2026-09-08 13:26:55.311747+00:00", "lang": "en", "topics": ["ai-products", "developer-tools", "artificial-intelligence"], "entities": ["GitHub", "HydraFusion", "Copilot CLI", "Claude Opus 5"], "alternates": {"html": "https://wpnews.pro/news/github-hydrafusion-copilot-now-routes-workflows-not-models", "markdown": "https://wpnews.pro/news/github-hydrafusion-copilot-now-routes-workflows-not-models.md", "text": "https://wpnews.pro/news/github-hydrafusion-copilot-now-routes-workflows-not-models.txt", "jsonld": "https://wpnews.pro/news/github-hydrafusion-copilot-now-routes-workflows-not-models.jsonld"}}
