Project Solara: Agent-First Devices Need a Platform, Not Just a Product

Project Solara is the most speculative part of Build 2026, and the most interesting. It is a software platform plus hardware concepts for agent-first devices. The argument is that agents are becoming a new unit of programming and a new interaction technology. If that is true, the device form factor should change too.

History says specialized computers find specific contexts. Laptops did not replace phones. Phones did not replace watches. Each form factor found its own place because it was better suited to a specific task or moment. Solara imagines a diverse ecosystem of agent-first hardware: different sizes, mobility levels, and professional contexts.

The platform play

Solara is not a single product. It is a stack: hardware, OS, AI runtime, agent orchestration, and developer tools. That makes it expensive and difficult. It also makes it defensible if Microsoft can attract partners. The risk is that Microsoft has a mixed record with platform bets outside Xbox and Azure.

The enterprise angle is that agent-first devices could change how fieldwork, healthcare, manufacturing, and logistics work. A device designed primarily for agentic interaction rather than app switching is a different proposition. The question is whether the market needs another device category, or whether existing form factors will absorb agentic capabilities over time.
