Browser Automation

How UI-TARS actually works UI-TARS represents a fundamental departure from traditional GUI automation tools by integrating perception, reasoning, action, and memory into a single end-to-end model. Unlike frameworks that rely on wrapped commercial models with predefined workflows, UI-TARS uses a pure-vision approach that processes screenshots directly. The architecture comprises four tightly integrated components: Perception System: Processes screenshots to understand GUI elements, their relationships, and context. The model identifies buttons, text fields, and interactive components with sub-5-pixel accuracy, allowing for precise interactions. ...

Functionality and Architecture Browser-use is an open-source AI-powered browser automation framework that lets AI agents control a web browser via natural language instructions. Under the hood, it combines large language models (LLMs) with a headless browser automation engine (built on Playwright/Chromium) to interpret tasks and perform web interactions autonomously . When given a task, the Browser-use Agent uses an LLM (like GPT-4o or Claude) to analyze the goal and the current webpage, then issues browser commands (clicks, form fills, navigation, etc.) to achieve that goal. ...
