Computer Use

Computer use is an agent capability where a model operates a computer GUI or browser — seeing screenshots or accessibility trees and issuing clicks, typing, and navigation actions.

It extends tool use from APIs to the full desktop/web environment.
Why It Matters in AI
Most real work lives in UIs without clean APIs. Computer-use agents automate legacy software, web workflows, and QA. They raise new reliability and safety stakes (irreversible clicks, credentials, prompt injection via page content).
Key Points
Aspect Description
I/O Screenshots/DOM in; mouse/keyboard/actions out
Eval WebArena, OSWorld-like desktop tasks
Risks Prompt injection from web, data exfil, destructive actions

Simple Analogy
A remote intern who watches your screen over video and moves the mouse for you — powerful, but you still need guardrails on what they can click.
Common Usage Examples
  • Anthropic computer-use tool demos
  • Browser agents booking flows
  • Desktop RPA with vision-language models
  • Sandbox VMs for safe execution
Summary
In short: Computer use lets agents control GUIs and browsers with vision and actions — automating software that has no clean API.
