Abstract
Autoregressive (AR) vision-language models (VLMs) have long dominated multimodal understanding, reasoning, and graphical user interface (GUI) grounding. Recently, discrete diffusion vision-language models (DVLMs) have shown strong performance in multimodal reasoning, offering bidirectional attention, parallel token generation, and iterative refinement. However, their potential for GUI grounding remains unexplored. In this work, we evaluate whether discrete DVLMs can serve as a viable alternative to AR models for GUI grounding. We adapt LLaDA-V for single-turn action and bounding-box prediction, framing the task as text generation from multimodal input. To better capture the hierarchical structure of bounding-box geometry, we propose a hybrid masking schedule that combines linear and deterministic masking, improving grounding accuracy by up to 6.1 points in Step Success Rate (SSR) over the GUI-adapted LLaDA-V trained with linear masking. Evaluations on four datasets spanning web, desktop, and mobile interfaces show that the adapted diffusion model with hybrid masking consistently outperforms the linear-masked variant and performs competitively with autoregressive counterparts despite limited pretraining. Systematic ablations reveal that increasing diffusion steps, generation length, and block length improves accuracy but also increases latency, with accuracy plateauing beyond a certain number of diffusion steps. Expanding the training data with diverse GUI domains further reduces latency by about 1.3 seconds and improves grounding accuracy by an average of 20 points across benchmarks. These results demonstrate that discrete DVLMs are a promising modeling framework for GUI grounding and represent an important step toward diffusion-based GUI agents.

WHY NOW
GUI Agents moved forward this cycle; last verified April 2026. Public score 7.0/10. Production flags indicate code availability.
In this work, we evaluate whether discrete DVLMs can serve as a viable alternative to AR models for GUI grounding.
The abstract explicitly states the paper's goal is to evaluate whether DVLMs can serve as a viable alternative for GUI grounding and the results demonstrate this.
partial
we propose a hybrid masking schedule that combines linear and deterministic masking, improving grounding accuracy by up to 6.1 points in Step Success Rate (SSR) over the GUI-adapted LLaDA-V trained with linear masking.
The abstract provides a specific quantitative improvement for the proposed hybrid masking schedule.
partial
These results demonstrate that discrete DVLMs are a promising modeling framework for GUI grounding and represent an important step toward diffusion-based GUI agents.
The abstract states the model performs competitively with AR counterparts, and the analysis section discusses AR models' dominance due to large-scale pretraining, implying the DVLM's competitiveness is notable.
partial
Systematic ablations reveal that increasing diffusion steps, generation length, and block length improves accuracy but also increases latency, with accuracy plateauing beyond a certain number of diffusion steps.
The abstract explicitly details the trade-off between these parameters and accuracy/latency.
partial
Expanding the training data with diverse GUI domains further reduces latency by about 1.3 seconds and improves grounding accuracy by an average of 20 points across benchmarks.
The abstract provides specific quantitative improvements attributed to expanding training data.
partial
Autoregressive (AR) vision–language models (VLMs) have long dominated multimodal understanding, reasoning, and graphical user interface (GUI) grounding.
The abstract and introduction clearly state the historical dominance of AR models in this domain.
partial
While effective for general multimodal understanding, random token corruption across diffusion steps introduces variations in masked sequences. Such randomness may disrupt the model’s ability to capture consistent geometric dependencies among these coordinates.
The paper explains the limitation of standard DVLMs regarding geometric dependencies and proposes a solution, implying this is a known issue.
partial
In this work, we evaluate whether discrete DVLMs can serve as a viable alternative to AR models for GUI grounding.
The abstract explicitly states this as the main research question and the results support it.
partial
we propose a hybrid masking schedule that combines linear and deterministic masking, improving grounding accuracy by up to 6.1 points in Step Success Rate (SSR) over the GUI-adapted LLaDA-V trained with linear masking.
This is a specific quantitative result directly stated in the abstract, comparing two methods.
partial
Evaluations on four datasets spanning web, desktop, and mobile interfaces show that the adapted diffusion model with hybrid masking consistently outperforms the linear-masked variant and performs competitively with autoregressive counterparts despite limited pretraining.
The abstract states consistent outperformance across multiple domains, indicating a robust result.
partial
Systematic ablations reveal that increasing diffusion steps, generation length, and block length improves accuracy but also increases latency, with accuracy plateauing beyond a certain number of diffusion steps.
This claim is supported by systematic ablations mentioned in the abstract, detailing trade-offs.
partial
Expanding the training data with diverse GUI domains further reduces latency by about 1.3 seconds and improves grounding accuracy by an average of 20 points across benchmarks.
This claim provides specific quantitative improvements attributed to data expansion.
