Agent S2 represents a versatile, expandable, and modular framework for computer-based agents, created by Simular. These autonomous AI agents are capable of direct interaction with graphical user interfaces (GUIs) across desktops, mobile devices, web browsers, and various software applications, effectively emulating human control through mouse and keyboard inputs. Building on the foundational aspects of the original Agent S framework, Agent S2 boosts both performance and modularity by incorporating cutting-edge frontier foundation models alongside specialized models. It has achieved remarkable success, particularly in outperforming prior benchmarks in evaluations such as OSWorld and AndroidWorld. Central to its design are several key principles, which include proactive hierarchical planning that allows the agent to adapt its strategies dynamically after completing each subtask; visual grounding that facilitates accurate GUI interaction through the use of raw screenshots; an enhanced Agent-Computer Interface (ACI) that assigns intricate tasks to specialized modules; and an agentic memory system designed to support continuous learning from past experiences. This innovative approach not only improves efficiency but also ensures that agents can better adapt to the ever-evolving technological landscape.
