Libraries

How to use Jackrong/Qwen3.5-4B-Python-Coder with Transformers:

# Use a pipeline as a high-level helper

messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
pipe(text=messages)

# Load model directly
from transformers import AutoProcessor, AutoModelForImageTextToText

processor = AutoProcessor.from_pretrained("Jackrong/Qwen3.5-4B-Python-Coder")
model = AutoModelForImageTextToText.from_pretrained("Jackrong/Qwen3.5-4B-Python-Coder")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
inputs = processor.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

⚠️ Preview Status

This repository is currently a preview release.

The model is still under active testing, and I am continuing to explore more suitable training settings and optimization strategies. Because of this, the current version should be considered experimental.

Downloading or using this model for serious evaluation is not recommended yet. A more stable version will be released after further testing and parameter tuning.
