Agentic OS
An agentic OS is an operating system with a built-in AI agent that finishes tasks across the device's apps when the user asks, by voice or text. AGI, Inc. builds the agent layer that device makers add to their operating system to make it agentic. It works in any app on the device, with no integrations.

Mobile use
Mobile use is an AI agent's ability to operate the apps on a phone or tablet and finish tasks for a person.
On-device action model
An on-device action model is an action model small enough to run on a phone's or PC's own chip.
Hybrid inference
Hybrid inference runs an AI model on the device where the hardware allows and sends heavier steps to the cloud or on-prem servers.
Agent layer
An agent layer is the part of a device's software that turns a person's request into finished tasks across the device's apps.
Also called | Agentic operating system, AI agent OS |
|---|---|
What it adds | An agent that finishes tasks inside the device's apps |
Who builds it | Device makers, on top of an existing operating system such as Android |
What it needs | An action model, an agent harness and an inference engine for the device's chip |
Where the agent runs | On the device where the hardware allows, in the cloud when a task needs more |
AGI's part | AGI-ACT action models, the agent harness and the AGI-RUN inference engine |
What makes an operating system agentic?
An operating system is agentic when it can finish a request instead of only starting one. Most built-in assistants answer a question or open an app. An agentic OS completes the task inside the app, such as ordering groceries in the delivery app the person already uses, and reports back when it is done. The agent works with the apps already on the device, including apps that have no API, so app makers do not need to build an integration.
How is an agentic OS different from a voice assistant?
A voice assistant answers questions and handles simple commands, while an agentic OS finishes whole tasks across apps.
Voice assistant | Assistant built on app APIs | Agentic OS | |
|---|---|---|---|
What it does | Answers questions, sets timers, opens apps | Finishes tasks in apps that built an integration | Finishes tasks in any installed app |
What app makers build | Nothing | An integration for each app | Nothing |
Example request | "What's the weather tomorrow?" | "Play my workout playlist" in a supported app | "Order my usual dinner" in the person's delivery app |
What does a device maker need to build an agentic OS?
An agentic OS needs three parts working together:
An action model that can operate apps
An agent harness that runs each task from start to finish and asks the user before payments
An inference engine that runs the model on the device's chip
AGI, Inc. provides all three as one agent layer, built from AGI-ACT, the agent harness and AGI-RUN. Device makers name the apps their customers use most, and AGI tunes the agent for those apps.
Does an agentic OS run on the device or in the cloud?
It can do both. AGI's stack runs on the device where the hardware allows and uses the cloud when a task needs more capacity. On a Samsung Galaxy S25 Ultra, the AGI-RUN engine averaged about five times the prefill throughput of each model's own engine, and up to 6.9 times. At Snapdragon Summit 2026, AGI's action model completed a task on a phone with no connection, running on the Snapdragon NPU.
Which devices can have an agentic OS?
Phones come first, and PCs are next. The same agent also works with wearables paired to a phone: at Snapdragon Summit 2026, AGI showed agentic commerce across smart glasses, a phone and a watch.
FAQ
Is an agentic OS a new operating system?
Usually not. It is an existing operating system, such as Android, with an agent layer added by the device maker. AGI, Inc. does not build operating systems. It builds the agent layer that makes one agentic.
Which apps does an agentic OS work with?
With AGI's agent layer, any app installed on the device. The agent uses apps the way a person does, so app makers do not need to build an integration or expose an API.
Does an agentic OS work without a connection?
For tasks the on-device model can handle, yes. Steps that need more capacity can use the cloud, and the device maker decides how much runs on the device.
How can a device maker try AGI's agent layer?
Talk to AGI, Inc. through the contact page. AGI tunes the agent to the apps a device maker's customers use most.
