Inefficient UI Representations: The Bottleneck
Our motivating study revealed that inefficient UI representation is a critical performance bottleneck for LLM agents. It consumes an astonishing 80% to 99% of total agent-token costs, significantly limiting scalability and practical deployment. Existing solutions either paradoxically increase token consumption or lose critical semantic information, hindering effective UI navigation and task completion.

DSL-Restricted Program Synthesis
UIFORMER utilizes a Domain-Specific Language (DSL) that captures UI-specific merge operations, enforcing semantic completeness and reducing search space. This DSL restricts LLMs to generate recursive code snippets that operate on parent-child node pairs, enabling principled UI consolidation that scales reliably across diverse applications, avoiding combinatorial explosion and ensuring valid transformations.
Iterative Refinement with LLM Feedback
The framework employs an LLM-based iterative refinement process. Candidate transformation programs are immediately evaluated against training examples using a composite reward function, balancing token efficiency and semantic completeness. Structured feedback guides the LLM to refine programs, systematically improving their quality and generalizability without extensive manual annotations.

Case Study: Improving Agent Effectiveness
In a tip calculation task, existing representations (like Leaf) fragment UI elements (e.g., 'Bill Amount' label and input field) into unconnected entries, preventing the LLM from determining which input field corresponds to which value, ultimately causing task failure. UIFORMER addresses this limitation by consolidating related elements into semantic units. For instance, the bill amount label and input field are transformed into a single EditText element with descriptive content “Bill Amount 0.00”. This semantic grouping enables the LLM to understand the functional relationship between interface components and correctly identify the target field for inputting “56.6” as the next action, significantly improving task success.
Real-world Deployment at WeChat
UIFORMER has been successfully deployed at WeChat within their Development and Engineering Tools (DET) team, serving over one billion monthly active users. It acts as a preprocessing component in the existing serving pipeline, transforming UI trees before they are fed to the LLM agents for automated GUI testing services, demonstrating its practical impact and scalability in industrial settings.
