Libraries

How to use luzimu/WebGenAgent-LM-7B-Step-GRPO with Transformers:

# Use a pipeline as a high-level helper

pipe = pipeline("image-text-to-text", model="luzimu/WebGenAgent-LM-7B-Step-GRPO")
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 AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("luzimu/WebGenAgent-LM-7B-Step-GRPO")
model = AutoModelForCausalLM.from_pretrained("luzimu/WebGenAgent-LM-7B-Step-GRPO")
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 = tokenizer.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(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

This PR enhances the model card by:

Adding pipeline_tag: image-text-to-text to the metadata for better discoverability.
Specifying library_name: transformers in the metadata, as the model's configuration (model_type: qwen2, tokenizer_class: Qwen2Tokenizer) indicates compatibility with the Hugging Face Transformers library. This will enable automated code snippets on the Hub.
Adding a direct link to the GitHub repository in the main content.
Including a "Sample Usage" section with a "Single Inference" code snippet, directly taken from the GitHub README, to help users get started easily.

All existing content and metadata, including the current arXiv paper link, have been preserved.
