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.

II-Agent is an open source intelligent assistant developed by Intelligent Internet, designed to enhance productivity across various domains such as research, content creation, data analysis, coding, automation, and problem-solving. It operates through a robust function-calling paradigm, driven by a powerful large language model (LLM), specifically Anthropic's Claude 3.7 Sonnet, and is supported by advanced planning, comprehensive execution capabilities, and intelligent context management. The agent's architecture includes a central reasoning and orchestration component that interfaces directly with the LLM, utilizing system prompting, interaction history management, and intelligent context management to maintain a coherent and efficient workflow. II-Agent's capabilities encompass multistep web search, source triangulation, structured note-taking, rapid summarization, blog and article drafting, lesson plan creation, creative prose, technical manuals, website creation, etc.
