Microsoft Unveils Project Solara, an Android OS for Agent-First Devices

The move signals Microsoft’s bid to reshape computing around cloud-based AI assistants through partner-built devices.

Overview

  • Project Solara, which Microsoft unveiled on Tuesday, June 2, 2026 at Build, is a chip-to-cloud platform that runs persistent AI agents instead of traditional apps and uses Microsoft Device Ecosystem Platform (MDEP), an enterprise version of Android.
  • Microsoft showed two reference concepts — a desk hub and a wearable badge — and said it will not sell those devices but expects hardware partners to turn the designs into products.
  • Qualcomm and MediaTek are named as initial silicon partners with the badge prototype on Qualcomm wearable chips and the desk hub on MediaTek IoT silicon, and companies including AccuWeather, Best Buy, CVS Health, Levi’s, and Target are signed up for pilots.
  • Microsoft also introduced Scout, a persistent assistant tied to Microsoft 365 and the Frontier program that will require GitHub Copilot access and operate primarily in the cloud.
  • The project is explicitly early and conceptual, with core questions about pricing, data flows, privacy, and which tasks run on-device versus in Azure still unresolved and next steps focused on partner pilots and further technical development.
