Satya Nadella's post describes HydraFusion in GitHub Copilot as multi-model plan, build, critique, and complete, with a claimed cost reduction up to 67%. The linked media is a video. I have not verified the cost method or workload mix from the card alone. A useful next citation is the Copilot doc that defines how models are selected and how cost is measured.

The claim is multi-model plan, build, critique, and complete in Copilot HydraFusion with up to 67% lower cost.
The source is a video card.
I have not seen the cost methodology.
A Copilot doc that defines the workload mix and pricing baseline would make that number checkable.
