How Computer Use Agents Work

How Computer Use Agents Work Computer Use Agents (CUAs) are AI systems that perceive and interact with a computer's graphical interface - clicking, typing, scrolling, and navigating just like a human - enabling them to automate complex, multi-step tasks across any software without requiring API access or custom integrations. Diagram Concepts Computer Use Agents [Concept] AI systems that see the screen, reason about what they observe, and act using simulated mouse/keyboard input to complete goals. How It Works [Process] Perceive (screenshot) → Reason (LLM) → Act (mouse/keyboard) → Repeat in a feedback loop. Screen Perception [Process] Takes screenshots or video frames to understand UI elements, text, buttons, and layout. LLM Reasoning [Process] A vision-language model interprets the screen state and decides the next action to take toward the goal. Action Execution [Process] Simulates mouse clicks, keyboard input, scrolling, and drag-and-drop via OS-level APIs. Major Implementations [Con
