Computer Use & GUI Agent (Anthropic Claude 3.5 Sonnet Computer Use, OS-World) is a multimodal agent paradigm that directly operates computer desktops by inspecting screen captures, grounding UI visual elements, and emitting native mouse clicks, drags, keystrokes, and hotkey actions; its core cycle consists of: 1) Capturing high-res screen state; 2) Multimodal Vision-Language Models (VLMs) resolving target UI element pixel coordinates
(x,y); 3) Emitting structured OS action commands; 4) Virtual display drivers (X11, PyAutoGUI) executing actions before looping back with a fresh verification screenshot.
