Libraries

How to use luzimu/WebGenAgent-LM-8B-Step-GRPO with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

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-8B-Step-GRPO")
model = AutoModelForCausalLM.from_pretrained("luzimu/WebGenAgent-LM-8B-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 the pipeline_tag: image-text-to-text to accurately reflect the model's functionality in processing visual (screenshots) and textual inputs to generate text (code).
Including library_name: transformers, as the model is compatible with the Hugging Face transformers library, which enables the automated "How to use" widget.
Adding a direct link to the GitHub repository (https://github.com/mnluzimu/WebGen-Agent) for improved discoverability of the codebase.
Updating the image paths to point to the raw assets on the GitHub repository to ensure they render correctly on the Hugging Face Hub.

These changes improve the model's discoverability and usability for the community.
