# GroundGUI RL Dataset

A reinforcement-learning (RLOO) corpus for desktop GUI grounding: 12,600
prompts over 11,205 screenshots from 87 desktop applications. Each prompt is a
screenshot plus a natural-language instruction, and the reward is whether the
predicted click lands inside the target element's bounding box.

All screenshots, instructions and boxes come from
[GroundCUA](https://huggingface.co/datasets/ServiceNow/GroundCUA) (MIT). This
release only selects and mixes samples and formats them as Qwen3-VL
`computer_use` tool-call prompts. None of its screenshots is identical to
any UI-Vision image.

## Usage

```python
import json
from datasets import load_dataset

ds = load_dataset("PrentisAI/GroundGUI_RL", split="train")
row = ds[0]
img = row["images"][0]                                       # PIL.Image
x1, y1, x2, y2 = row["solution"]["arguments"]["coordinate"]  # target box, absolute pixels
extra = json.loads(row["additional_paras"])                  # JSON string: image_size, app, slice, ...
```

`messages` holds the system, user and assistant turns. The assistant turn is
a reference answer: the box centre in 0–1000 normalised coordinates. Compute
the reward from `solution`.
