Multi-modal Massive Language Fashions (MLLMs) have demonstrated outstanding capabilities throughout varied domains, propelling their evolution into multi-modal brokers for human help. GUI automation brokers for PCs face significantly daunting challenges in comparison with smartphone counterparts. PC environments current considerably extra advanced interactive components with dense, numerous icons and widgets usually missing textual labels, resulting in notion difficulties. Even superior fashions like Claude-3.5 obtain solely 24.0% accuracy in GUI grounding duties. Additionally, PC productiveness duties contain intricate workflows spanning a number of purposes with prolonged operation sequences and inter-subtask dependencies, inflicting dramatic efficiency declines the place GPT-4o’s success price drops from 41.8% at subtask stage to simply 8% for full directions.
Earlier approaches have developed frameworks to deal with PC job complexity with various methods. UFO implements a dual-agent structure separating software choice from particular management interactions. In the meantime, AgentS augments planning capabilities by combining on-line search with native reminiscence. Nonetheless, these strategies display vital limitations in fine-grained notion and operation of on-screen textual content—a essential requirement for productiveness eventualities like doc modifying. As well as, they often fail to deal with the advanced dependencies between subtasks, leading to poor efficiency when dealing with life like intra- and inter-app workflows that characterize on a regular basis PC utilization.
Researchers from MAIS, Institute of Automation, Chinese language Academy of Sciences, China, College of Synthetic Intelligence, College of Chinese language Academy of Sciences, Alibaba Group, Beijing Jiaotong College, and College of Data Science and Expertise, ShanghaiTech College introduce PC-Agent framework to deal with advanced PC eventualities by way of three revolutionary designs. First, the Energetic Notion Module enhances fine-grained interplay by extracting areas and meanings of interactive components by way of accessibility bushes, whereas utilizing MLLM-driven intention understanding and OCR for exact textual content localization. Second, Hierarchical Multi-agent Collaboration implements a three-level choice course of (Instruction-Subtask-Motion) the place a Supervisor Agent decomposes directions into parameterized subtasks and manages dependencies, a Progress Agent tracks operation historical past, and a Determination Agent executes steps with notion and progress info. Third, Reflection-based Dynamic Determination-making introduces a Reflection Agent that assesses execution correctness and offers suggestions, enabling top-down job decomposition with bottom-up precision suggestions throughout all 4 collaborating brokers.
PC-Agent’s structure addresses GUI interplay by way of a formalized method the place an agent ρ processes person directions I, observations O, and historical past H to find out actions A. The Energetic Notion Module enhances component recognition utilizing pywinauto to extract accessibility bushes for interactive components whereas using MLLM-driven intention understanding with OCR for exact textual content localization. For advanced workflows, PC-Agent implements Hierarchical Multi-agent Collaboration throughout three ranges: the Supervisor Agent decomposes directions into parameterized subtasks and manages dependencies; the Progress Agent tracks operation progress inside subtasks; and the Determination Agent executes step-by-step actions primarily based on environmental notion and progress info. This hierarchical division successfully reduces decision-making complexity by breaking advanced duties into manageable parts with clear interdependencies.
Experimental outcomes display PC-Agent’s superior efficiency in comparison with each single and multi-agent options. Single MLLM-based brokers (GPT-4o, Gemini-2.0, Claude3.5, Qwen2.5-VL) persistently fail on advanced directions, with even the most effective performer attaining solely 12% success price, confirming that single-agent approaches battle with prolonged operational sequences and sophisticated dependencies. Multi-agent frameworks like UFO and AgentS present modest enhancements however stay restricted by notion deficiencies and dependency administration points. They battle with fine-grained operations corresponding to textual content modifying in Phrase or correct information entry in Excel, and infrequently fail to make the most of info from earlier subtasks. In distinction, PC-Agent considerably outperforms all earlier strategies, surpassing UFO by 44% and AgentS by 32% in success price by way of its Energetic Notion Module and hierarchical multi-agent collaboration.
This research introduces PC-Agent framework, a big development in dealing with advanced PC-based duties by way of three key improvements. The Energetic Notion Module offers refined notion and operation capabilities, enabling exact interplay with GUI components and textual content. The hierarchical multi-agent collaboration structure successfully decomposes decision-making throughout instruction, subtask, and motion ranges, whereas reflection-based dynamic decision-making permits for real-time error detection and correction. Validation by way of the newly created PC-Eval benchmark with life like, advanced directions confirms PC-Agent’s superior efficiency in comparison with earlier strategies, demonstrating its effectiveness in navigating the intricate workflows and interactive environments attribute of PC productiveness eventualities.
