Computer Use

▲ Rising

Letting a model drive a real computer the way a person does — looking at the screen, moving the mouse, typing.

Think of it like

A remote assistant on a screen-share who can see your desktop and click around to get things done.

Example

Asked to file an expense, the agent takes a screenshot, finds the form fields, clicks them, types the amounts, and hits submit.

How it actually works

The model is fed screenshots and returns actions — click at these coordinates, type this, scroll — in a loop, letting it use any app without a dedicated API. It is powerful and brittle: pixel-level targeting misfires, pages shift, and a wrong click can do real damage. Because it can touch anything on screen, it is one of the higher-risk agent modes and usually runs behind confirmations.

For product teams

It promises automation of any app, but reliability and safety are the whole ballgame.

For engineers

A vision-driven agent loop that maps screenshots to GUI actions (click, type, scroll) via coordinates.
