Usage

python

from transformers import Qwen2_5_VLForConditionalGeneration, AutoProcessor
from qwen_vl_utils import process_vision_info
import torch
 
model_id = "vorenthiclabs/vorenthos-vision-coding-qwen25vl-7b"
processor = AutoProcessor.from_pretrained(model_id)
model = Qwen2_5_VLForConditionalGeneration.from_pretrained(
    model_id, torch_dtype=torch.float16, device_map="auto"
)
 
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "image": "https://your-code-screenshot.png"},
            {"type": "text",  "text": "Reproduce the code shown in this screenshot."}
        ]
    }
]
text   = processor.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = processor(text=[text], images=[...], return_tensors="pt").to(model.device)
output = model.generate(**inputs, max_new_tokens=1024, temperature=0.1)
print(processor.decode(output[0], skip_special_tokens=True))

Best use cases

Screenshot → working code
UI mockup → HTML/CSS
Math diagram → LaTeX / pseudocode
Technical document → structured extraction
