Microsoft bets on local AI: Windows agent stack spans $800 Copilot+ PCs to 1T-param DGX Station

A Signal65 report maps Microsoft's Build 2026 vision of rebuilding Windows for the agentic era around "unmetered intelligence": run AI locally to avoid per-token costs and cloud round trips, escalate to cloud when needed, with OS-level agent governance for enterprises. Hardware tiers: mainstream Copilot+ PCs ($800-2,500); high-end Surface RTX Spark Dev Box at up to 1 petaflop with 128GB unified memory plus AMD Ryzen AI Max boxes running 100B+ parameter models; frontier GB300 DGX Station for up to 1 trillion parameters and workstations pooling 192-384GB across RTX PRO 6000 Blackwell GPUs. Developers build and govern agents the same way across all three tiers. Ryan Shrout says the AI compute transition is still early and Microsoft aims to capture a big piece of it.
