Concept

Computer use

Verified Oct 17, 2026 Review by Apr 15, 2027 3 sources
Short answer

Computer use lets an AI model operate a computer the way a person does: look at screenshots, move the mouse, click and type. It reaches apps that have no API. It is slower and more error-prone than an API, so use it for gaps, in a sandbox, with human approval for anything that matters.

What it is

Computer use is a tool type where the model receives screenshots and returns actions such as clicks and keystrokes. Anthropic documents a computer use toolset (screenshot, click, type, zoom and more) that runs in an environment you control. OpenAI documents computer use for operating browser and desktop interfaces. AWS offers Nova Act, a service for building agents that automate browser-based UI workflows.

How it works

  1. The agent takes a screenshot of a desktop or browser.
  2. The model decides the next action and returns it.
  3. Your harness performs the action and sends a new screenshot, repeating until the task is done.

OpenAI’s example uses an approval callback, so the application decides which actions are allowed before they run.

Benefits

  • Automates legacy or web-only tools that have no integration.
  • Can follow the same steps a staff member would.
  • Useful for testing websites and user flows.

Limits and risks

  • Slow, and brittle when layouts change.
  • On-screen content can carry prompt injection. Anthropic recommends a dedicated virtual machine or container with minimal privileges, and keeping login details and other sensitive data away from the model.
  • Keep credentials and payments out of reach, and require human approval for anything that matters.
  • Status varies by vendor. Anthropic labels its SDK computer toolset as beta, so check each vendor’s docs before relying on it in production.
