Microsoft is taking a big swing at what comes after PCs, phones, and tablets with a new platform called Project Solara. Framed as a “chip‑to‑cloud” system for agent‑first devices, Solara is designed to power hardware that’s built around AI agents instead of traditional apps and windows. In a lengthy blog post, Steven Bathiche, CVP and Technical Fellow in Microsoft’s Applied Sciences Group, lays out how Solara aims to make it easier and cheaper to create highly specialized devices that bring agents closer to real‑world workflows and environments.
The idea is that agents—like Microsoft 365 Copilot and other specialized assistants—become both the new unit of programming and the primary human‑computer interface. Rather than opening an app and clicking through menus, you talk, type, or gesture at an agent that orchestrates work across multiple apps, services, and devices. Project Solara is Microsoft’s attempt to standardize the hardware, software, and cloud pieces needed to make those agent‑first experiences feel native, secure, and scalable.
From Apps to Agents: Why Project Solara Exists
Bathiche frames Solara as the next step in a long evolution of computing form factors. Mainframes gave way to PCs, PCs to phones, phones to wearables, but each new wave added more specialization instead of replacing what came before. Now, Microsoft argues that AI agents are the new interaction technology that will unlock another wave of highly specialized devices.
Historically, building any new kind of computer has been painfully expensive: you needed custom hardware, an OS, app frameworks, developer tools, a security model, and a healthy app ecosystem to make it all worth it. Solara’s core bet is that agents and AI can dramatically lower that barrier. If an agent can generate or adapt its own interface and workflows, you don’t need a full stack of custom apps and UI frameworks for every new device. Instead, you can focus on the form factor, sensors, and specific jobs to be done, and let the agent plus cloud handle much of the experience.
That’s where concepts like “just‑in‑time UI” come in. Rather than designing rigid screens for every resolution and input method, an agent can adapt its presentation to different devices—voice‑first, screen‑first, or multimodal—without developers reinventing the UI for each hardware SKU.
What Project Solara Actually Is
Project Solara is described as a chip‑to‑cloud platform that treats the “operating system” as something liminal—spanning both the device and Azure. On the device side, you get a lightweight window into your agents; in the cloud, those agents maintain state, context, and workflows that can span multiple specialized devices.
Microsoft calls out three main pillars for the platform:
-
Enterprise readiness – baked‑in identity, manageability, security, privacy, and user control so these devices can live in corporate environments.
-
Agent‑driven interaction with just‑in‑time UI – devices are designed for agents instead of traditional apps, and UI adapts dynamically to device capabilities and modalities.
-
Extensibility and “bring your own agents” – organizations can use Microsoft’s agents, build their own, or adopt third‑party agents and have them work together coherently.
Under the hood, Solara leans on several existing Microsoft technologies and requirements:
-
Microsoft Device Ecosystem Platform (MDEP), an enterprise‑grade OS based on AOSP
-
An “Agent Shell” that can dynamically load and host multiple cloud‑based agents
-
Management via Microsoft Intune
-
Identity via Entra ID and authentication via Windows Hello for Business
-
Physical privacy controls like mic mute and recording indicators
-
Approved silicon platforms and reference designs for OEMs to build on
The result is meant to be a repeatable blueprint for agent‑first hardware, rather than a one‑off science project.
Just‑In‑Time UI and a World of Many Agents
A key concept in the blog post is just‑in‑time UI: the idea that agents can adapt their interface in real time to fit whatever device they’re running on. Today that looks like semi‑structured approaches—adaptive cards, known content types, and responsive layouts. Over time, Microsoft expects this to evolve toward more generative interfaces where AI can assemble UI “frame by frame” with minimal predefined structure.
Solara is intentionally targeting the middle of that spectrum right now. It goes beyond basic responsive web design but stops short of fully generative, unconstrained UI. The practical goal is simple: the same agent should be able to show a sensible experience on a tiny wearable, a glanceable desk display, or a full monitor without developers rebuilding the entire front‑end three times.
Microsoft is also explicit that there won’t be one agent to rule them all. Instead, there will be many domain‑specific agents—coding agents, healthcare agents, retail agents, and so on. Solara is meant to host and coordinate these agents through things like an agent dispatcher and an agent task manager, so the right agent surfaces at the right time without users having to “launch” them like apps.
The First Concept Devices: Badge and Desk Companions
To make Solara feel real, Microsoft is showing off two reference concept devices: a portable badge and an in‑place desk companion. These aren’t guaranteed products, but they’re meant to guide OEMs and show what an agent‑first device might look like.
Badge concept: an agent on your lanyard
The badge concept reimagines the everyday work access badge as a tiny, always‑connected agent device. It’s aimed at information workers, nurses, and other frontline staff who are constantly moving around.
Important device capabilities include:
-
Small touchscreen display
-
Windows Hello for Business fingerprint sensor for secure, tap‑to‑unlock access
-
Physical privacy switch and volume controls
-
Far‑field microphone array and speaker for voice interactions
-
Side‑facing camera for capturing context with permission
-
Wi‑Fi, Bluetooth, GNSS, and optional 5G connectivity
-
Qualcomm wearable silicon under the hood
On this badge, agents like Priority Agent, Facilitator, or a voice‑first Microsoft 365 Copilot can be one tap away, giving workers quick access to what’s next on their schedule, capturing hallway conversations with transcription and action items, or surfacing urgent tasks without a full PC in front of them.
Desk concept: a dedicated agent screen
The desk concept is a humble desk‑side companion device for knowledge workers. It’s meant to sit next to, or sometimes replace, a traditional PC setup while giving you frictionless access to your agents.
Capabilities include:
-
Touchscreen display
-
Windows Hello for Business with face authentication
-
Physical privacy and mic mute buttons
-
Dual far‑field microphones and a full‑range speaker
-
UWB presence sensor
-
Two USB‑C ports for power, external displays, and peripherals
-
Wi‑Fi and Bluetooth connectivity
-
MediaTek IoT silicon platform
This device can run standalone as an agent station, act as a companion to a Windows PC (with task hand‑off and shared lock state), or even become your Windows 365 thin client when plugged into an external monitor. Think calendar glances, prioritized to‑dos, and voice‑driven Copilot interactions that are always “on” without cluttering your main PC screens.
Together, the badge and desk designs highlight what Microsoft means by agent‑first hardware: devices shaped around agents, environments, and workflows, not around app icons and traditional desktops.
Silicon Partners, Pilots, and How to Build for Solara
Project Solara is also a business and ecosystem story. Microsoft is working with Qualcomm and MediaTek as its initial silicon partners to power early concept designs and future form factors.
-
Qualcomm is collaborating on portable and wearable concepts, leaning on its strengths in low‑power, always‑connected silicon for wearables and mobile devices.
-
MediaTek is partnering on stationary and IoT‑centric designs, tapping into its broad presence in edge and embedded hardware.
Inside Microsoft, hundreds of employees are already piloting Solara devices in real‑world workflows, and the company plans private pilots with brands like AccuWeather, Best Buy, CVS Health, Levi’s, Target, and others. The idea is to validate how agent‑first devices can streamline work in healthcare, retail, financial services, field service, and more.
For developers and companies building agents today, Solara is meant to feel familiar rather than totally new. You can:
-
Extend Microsoft 365 Copilot with declarative or custom agents
-
Use Copilot Studio to build and orchestrate agents
-
Build on the Microsoft 365 Agents SDK and the Microsoft Agent Framework
If you’re already investing in Microsoft 365, Azure, and Copilot tooling, Microsoft’s message is: you’re on the right path to target Solara devices when they become broadly available.
Why Project Solara Matters
Project Solara is still early, and Microsoft isn’t promising specific products or timelines yet. But the vision is clear: as the cost of specialization drops, innovation in device form factors can accelerate. Instead of squeezing every workflow into a laptop or smartphone, organizations could roll out dedicated agent devices tuned for a factory floor, a hospital room, a retail aisle, or a classroom.
For Microsoft, Solara is a way to extend the reach of its agent ecosystem beyond the PC and phone, deepening the role of Microsoft 365, Azure, and Copilot in everyday work. For developers and enterprises, it’s an invitation to think beyond apps and start designing around agents, environments, and jobs to be done.
If you’re already building agents on Microsoft 365 and Azure, Project Solara is essentially Microsoft telling you: keep going. Those agents won’t be limited to today’s screens—they’re destined to show up in a new generation of agent‑first devices that are built around them from day one.
