Massive Language Fashions (LLMs) and Imaginative and prescient Language Fashions (VLMs) have revolutionized the automation of cell system management by way of pure language instructions, providing options for advanced person duties. The standard method, “Step-wise GUI brokers,” operates by querying the LLM at every GUI state for dynamic decision-making and reflection, repeatedly processing the person’s process, and observing the GUI state till completion. Nevertheless, this methodology faces vital challenges because it depends closely on highly effective cloud-based fashions like GPT-4 and Claude. This raises essential issues about privateness and safety dangers when sharing private GUI pages, substantial user-side visitors consumption, and excessive server-side centralized serving prices, making large-scale deployment of GUI brokers problematic.
Earlier makes an attempt to automate cell duties relied closely on template-based strategies like Siri, Google Assistant, and Cortana, which used predefined templates to course of person inputs. Extra superior GUI-based automation emerged to deal with advanced duties with out relying on third-party APIs or intensive programming. Whereas some researchers centered on enhancing Small Language Fashions (SLMs) by way of GUI-specific coaching and exploration-based data acquisition, these approaches confronted vital limitations. Script-based GUI brokers significantly struggled with the dynamic nature of cell apps, the place UI states and components incessantly change, making data extraction and script execution difficult.
Researchers from the Institute for AI Trade Analysis (AIR), Tsinghua College have proposed AutoDroid-V2 to analyze tips on how to construct a robust GUI agent upon the coding capabilities of SLMs. Not like conventional step-wise GUI brokers that make choices one motion at a time, AutoDroid-V2 makes use of a script-based method that generates and executes multi-step scripts primarily based on person directions. Furthermore, it addresses two essential limitations of standard approaches:
- Effectivity: Brokers can generate a single script for a collection of GUI actions to finish a process primarily based on the person process, considerably decreasing question frequency and consumption.
- Functionality: Script-based GUI brokers rely on the coding skill of SLMs, which have been confirmed efficient by quite a few present research on light-weight coding assistants.
AutoDroid-V2’s structure consists of two distinct phases: offline and on-line processing. Within the offline stage, the system begins by establishing an app doc by way of a complete evaluation of the app exploration historical past. This doc serves as a basis for script technology, incorporating AI-guided GUI state compression, ingredient XPath auto-generation, and GUI dependency evaluation to make sure each conciseness and precision. In the course of the on-line stage, when a person submits a process request, the personalized native LLM generates a multi-step script, which is then executed by a domain-specific interpreter designed to deal with runtime execution reliably and effectively.
AutoDroid-V2’s efficiency is evaluated throughout two benchmarks, testing 226 duties on 23 cell apps in opposition to main baselines together with AutoDroid, SeeClick, CogAgent, and Mind2Web. It reveals vital enhancements, attaining a ten.5%-51.7% larger process completion charge whereas decreasing computational calls for with 43.5x and 5.8x reductions in enter and output token consumption respectively, and 5.7-13.4× decrease LLM inference latency in comparison with baselines. Testing throughout completely different LLMs (Llama3.2-3B, Qwen2.5-7B, and Llama3.1-8B) AutoDroid-V2, reveals constant efficiency with success charges starting from 44.6% to 54.4%, sustaining a secure reversed redundancy ratio between 90.5% and 93.0%.
In conclusion, researchers launched AutoDroid-V2 which represents a major development in cell process automation by way of its modern document-guided, script-based method using on-device SLMs. The experimental outcomes reveal that this script-based methodology considerably improves the effectivity and efficiency of GUI brokers, attaining accuracy ranges similar to cloud-based options whereas sustaining device-level privateness and safety. Regardless of these achievements, the system faces limitations when coping with apps missing structured textual content representations of their GUIs, comparable to Unity-based and Net-based purposes. Nevertheless, this problem may very well be addressed by integrating VLMs) to get better structured GUI representations primarily based on visible options.
