Qwen-Click-DiT

Vision-Language Model with Diffusion Transformer for GUI Click Prediction. For more, read here.

Model Description

This model predicts click coordinates given a screenshot and natural language instruction. It uses:

Qwen2.5-VL-3B as a frozen vision-language backbone
DiT (Diffusion Transformer) action head using flow matching

Quick Start

Installation

bash

pip install torch transformers accelerate qwen-vl-utils pillow
git clone https://github.com/HusseinLezzaik/Qwen-Click-DiT.git
cd Qwen-Click-DiT

Inference

python

import torch
from PIL import Image
from transformers import AutoProcessor, AutoConfig
from qwen_vl_utils import process_vision_info

# Clone the repo first to get the model class
from src.model import Qwen2_5_VLForClickPrediction

# Load model

# Prepare input

    "role": "user",
    "content": [
        {"type": "image", "image": image, "min_pixels": 200704, "max_pixels": 401408},
        {"type": "text", "text": prompt},
    ],
}]

text = processor.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
image_inputs, video_inputs, video_kwargs = process_vision_info(messages, return_video_kwargs=True)
inputs = processor(text=text, images=image_inputs, videos=video_inputs, return_tensors="pt", **video_kwargs)
inputs = {k: v.to("cuda") if torch.is_tensor(v) else v for k, v in inputs.items()}

# Predict click coordinates
with torch.no_grad():
    click_xy = model.predict(**inputs)

x, y = click_xy[0].cpu().tolist()
print(f"Normalized: ({x:.4f}, {y:.4f})")
print(f"Pixels: ({int(x * image.width)}, {int(y * image.height)})")
