Overview

Open-source GUI agent framework that lets an LLM use your computer like a human via an Agent-Computer Interface.

Agent S is an open-source framework for building and running “computer use” GUI agents that can autonomously operate a computer through an Agent-Computer Interface. It’s designed to let an LLM plan and execute multi-step tasks by observing the screen and taking actions (e.g., clicking, typing, navigating) on supported platforms (Linux, macOS, Windows). The project provides a CLI to run the agent, supports multiple model providers (including OpenAI, Anthropic, Gemini, OpenRouter, and vLLM), and recommends pairing a main LLM with a separate grounding model for UI understanding. Agent S also includes evaluation assets and reports results on established computer-use benchmarks such as OSWorld.

Autonomy level

75%

Reasoning: Agent S demonstrates high autonomy as a GUI agent capable of autonomous interaction with computers through direct keyboard and mouse control. It autonomously decomposes complex, multi-step tasks into executable subtasks using experience-augmented hierarchical planning. The framework operates with an Experience-Augmented Hierarchical Planning method...
