GitHub reports offline results for HydraFusion model orchestration

GitHub reports controlled offline results for its HydraFusion research preview in Copilot: on TerminalBench 2.1, quality was 4.9 points higher and estimated cost 67% lower than Opus 5. Quality was slightly lower on the other two benchmarks. Results depend on the evaluated setup and pricing assumptions, not every task or actual bill.
