About

Agent S2 is an open, modular, and scalable framework for computer-use agents developed by Simular. These autonomous AI agents interact directly with graphical user interfaces (GUIs) on desktops, mobile devices, browsers, and various software applications, mimicking human-like control via mouse and keyboard. Building upon the initial Agent S framework, Agent S2 enhances performance and modularity by integrating both frontier foundation models and specialized models. It achieves state-of-the-art results, notably surpassing previous benchmarks on OSWorld and AndroidWorld evaluations. Key design principles include proactive hierarchical planning, where the agent dynamically updates its plans after each subtask; visual grounding for precise GUI interaction using raw screenshots; an improved Agent-Computer Interface (ACI) that delegates complex tasks to specialized modules; and an agentic memory mechanism that enables continual learning from experience.

About

Action State Labs develops infrastructure for native Android AI agents, including an open-source driver called Android Use that lets AI agents interact with native Android apps reliably and efficiently by connecting directly to the Android Accessibility Tree instead of relying on brittle computer vision methods. This approach enables AI agents to read and control app UIs with higher speed, lower cost (up to ~95% cheaper), and greater robustness against UI changes, making it easier to automate complex workflows like logistics, field operations, and other tasks traditionally done in native mobile apps. It includes an open source core that runs on local devices or emulators and a managed cloud option with auto-scaling for enterprise use, API endpoints, and support services, letting developers build, test, and deploy agent-powered automation workflows across many devices concurrently.
