Satya Nadella: Windows Local AI Runtime Ships June 9 — Agents Run Entirely On-Device with Bundled Phi-4 Model

Windows News·high signal

Microsoft announced Windows Local AI, a system-level runtime shipping June 9 in Windows 11 24H2 that lets developers deploy AI agents running entirely on NPU/GPU/CPU silicon with zero cloud dependency. It bundles Phi-4-mini-silicon (2B params) and Phi-4-vision-silicon (7B), exposes a unified ONNX graph via Windows Copilot Runtime API, and runs agents in a sandbox with no network access by default. Minimum requirement: 40 TOPS NPU. For builders: local-first AI agents on Windows are now a platform-supported reality.
