## Model Description

VISTA-9B is a GUI-grounding model that maps a screenshot and a natural-language instruction to a click coordinate in the normalized `0-1000` image frame.

- **View-consistent GRPO training.** VISTA builds each GRPO comparison group from target-preserving views of the same GUI instance, with exact coordinate remapping across cropped views. This exposes localization behavior under semantically equivalent but geometrically different screenshots.
- **Self-verified cross-view anchoring.** The training objective adds an oracle-format center-point anchor only when model-generated rollouts have already produced a maximum-reward prediction, stabilizing short coordinate generation without unconditional imitation on all-fail groups.


## Evaluation

Accuracy is reported for GUI grounding. The model predicts a normalized coordinate in the `0-1000` frame, and the prediction is counted as correct if the point lies inside the target element. All reported results use deterministic decoding at temperature 0 and single-view inference.

## Quick Start

Use the same image-chat interface as the underlying Qwen3.5 vision-language model. The recommended prompt is:

```text
Output the center point of the position corresponding to the instruction: {instruction}. The output should just be the coordinates of a point, in the format [x,y].
```

Example:

```python
import torch
from PIL import Image
from transformers import AutoModelForImageTextToText, AutoProcessor

model_id = "inclusionAI/VISTA-9B"  

model = AutoModelForImageTextToText.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto",
    trust_remote_code=True,
)
processor = AutoProcessor.from_pretrained(model_id, trust_remote_code=True)

image = Image.open("screenshot.png").convert("RGB")
instruction = "Click the search button"
prompt = (
    "Output the center point of the position corresponding to the instruction: "
    f"{instruction}. The output should just be the coordinates of a point, "
    "in the format [x,y]."
)

messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "image": image},
            {"type": "text", "text": prompt},
        ],
    }
]

text = processor.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True,
)
inputs = processor(
    text=[text],
    images=[image],
    padding=True,
    return_tensors="pt",
).to(model.device)

generated = model.generate(
    **inputs,
    max_new_tokens=32,
    do_sample=False,
)
new_tokens = generated[:, inputs.input_ids.shape[1]:]
response = processor.batch_decode(new_tokens, skip_special_tokens=True)[0].strip()
print(response)  # e.g. [512,384]
```
