How Project HydraFusion reduces the cost of frontier AI

Why watch

GitHub engineers explain HydraFusion, a model orchestration system that routes requests across multiple AI models instead of selecting a single model. The system uses two workflows—Cascade (chain of models where each handles what the previous couldn't) and Critic (one model generates, another reviews)—achieving 42-47% cost savings while maintaining quality. Targeted at developers using Git Copilot who want to understand the cost optimization behind AI-assisted coding.
