What is a Computer Use AI?

Most AI automation talks to software through APIs: a defined, structured contract for reading and writing data. Computer use flips that — the model is shown a screenshot, decides where to click or what to type based on visual understanding of the interface, and takes the action, then observes the resulting screen and continues. This lets an agent operate software that has no API at all, including legacy desktop applications, or interfaces a vendor never opened up for programmatic access. The capability is powerful precisely because it's general — the same model can, in principle, use any application a human can — but it's also slower and less reliable than an API call, since it depends on correctly interpreting a visual layout that can shift with a UI redesign or a modal dialog appearing unexpectedly. It's typically used as a fallback path: try the structured API first, and only fall back to computer use when no API exists. Safety design matters more here than for API-based automation, since a misclick can trigger a real, hard-to-reverse action — a sent email, a submitted form, a deleted file — so production systems constrain computer use to sandboxed environments or require confirmation before consequential actions.
