Abstract

Recent advancements in Multi-modal Large Language Models (MLLMs) have led to significant progress in developing GUI agents for general tasks such as web browsing and mobile phone use. However, their application in professional domains remains under-explored. These specialized workflows introduce unique challenges for GUI perception models, including high-resolution displays and complex environments which lead to smaller target sizes. In this paper, we introduce ScreenSpot-Pro, a new benchmark designed to rigorously evaluate the grounding capabilities of MLLMs in high-resolution professional settings. The benchmark comprises authentic high-resolution images from a variety of professional domains with expert annotations. It spans 23 applications across five industries and three operating systems. Existing GUI grounding models perform poorly on this dataset, with the best model achieving only 18.9%. Our experiments reveal that strategically reducing the search area enhances accuracy. Based on this insight, we propose ScreenSeekeR, a visual search method that utilizes the GUI knowledge of a strong planner to guide a cascaded search, achieving state-of-the-art performance with 48.1% without any additional training. We hope that our benchmark and findings will advance the development of GUI agents for professional settings.

TL;DR

ScreenSpot-Pro is a new benchmark of 1,581 expert-annotated GUI grounding instructions in authentic high-resolution professional screenshots across 23 applications and 3 operating systems. Existing grounding models perform poorly on it, while the proposed training-free ScreenSeekeR visual-search method raises OS-Atlas-7B from 18.9% to 48.1%.

Key findings

  • ScreenSpot-Pro contains 1,581 instructions, each in a unique screenshot, spanning 23 applications across five industries and three operating systems; targets occupy 0.07% of the screenshot area on average, versus 2.01% in ScreenSpot, and text elements constitute 62.6% of targets.
  • The best existing GUI grounding model, OS-Atlas-7B, achieves only 18.9% overall accuracy; GPT-4o scores 0.9% on direct grounding, and no other model except UGround and AriaUI exceeds 10%.
  • ScreenSeekeR boosts OS-Atlas-7B from 18.9% to 48.1% without additional training, a 254% relative improvement; the simpler ReGround baseline reaches 40.2% with OS-Atlas-7B.
  • Icons are harder to ground than text, and Chinese instructions reduce performance: OS-Atlas-7B falls to 16.8%, while UGround-7B drops from 16.4% to 7.7%.

Methods

  • Benchmark construction: experts with at least five years of experience in the relevant applications recorded real work routines using a silently running screen-capture tool; screenshots were prioritized above 1080p (1920×1080), monitor scaling was disabled, and dual-monitor setups were captured across both displays. Each instance was reviewed by at least two annotators, with targets classified as text or icon.
  • Evaluation: models are scored by whether the center point of the predicted bounding box falls inside the annotated ground-truth box; end-to-end models tested include QwenVL-7B, Qwen2-VL-7B, MiniCPM-V-2.6 (8B), CogAgent (18B), SeeClick (7B), UGround (7B), OS-Atlas-4B/7B, ShowUI (2B), and Aria-UI (MoE, 3.9B active).
  • ScreenSeekeR: an agentic visual-search framework using GPT-4o as planner and OS-Atlas-7B as grounder; it performs position inference, candidate-area scoring with box dilation and NMS, recursive search, and invokes the grounder when patch size is sufficiently small (1280 pixels), with σ set to 0.3.

Limitations

  • The paper states that the benchmark is specifically designed to evaluate GUI grounding, excluding agent planning and execution tasks like those in OSWorld, to mitigate potential legal risks from software licensing restrictions.
  • Evident from the text: the benchmark covers only 23 applications across 3 operating systems and focuses on high-resolution professional settings, so generalization to other applications, resolutions, or full agent workflows is not established; the proposed ScreenSeekeR also depends on a proprietary GPT-4o planner and a specific OS-Atlas-7B grounder in the reported experiments.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
