wave-ui-3b

Fine-tuned Qwen/Qwen2.5-VL-3B-Instruct on agentsea/wave-ui-25k for UI element grounding — given a screenshot and a button name, returns the bounding box coordinates.

Usage

python

from transformers import Qwen2_5_VLForConditionalGeneration, Qwen2_5_VLProcessor
from qwen_vl_utils import process_vision_info
from PIL import Image
import torch, re

model     = Qwen2_5_VLForConditionalGeneration.from_pretrained(
    "miketes/wave-ui-3b", torch_dtype=torch.bfloat16, device_map="auto"
)
processor = Qwen2_5_VLProcessor.from_pretrained("miketes/wave-ui-3b")
image     = Image.open("screenshot.png").convert("RGB")

messages = [{
    "role": "user",
    "content": [
        {"type": "image", "image": image},
        {"type": "text",  "text": 'Where is the "login button"? Return the bounding box.'},
    ],
}]

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

with torch.inference_mode():
    out = model.generate(**inputs, max_new_tokens=64, do_sample=False)

result = processor.decode(out[0][inputs["input_ids"].shape[1]:], skip_special_tokens=True)
coords = re.findall(r'\d+', result)
bbox   = [int(x) for x in coords[:4]] if len(coords) >= 4 else None
print(bbox)  # [678, 99, 772, 138]
