Instructions to use MegaScience/Qwen2.5-3B-MegaScience with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use MegaScience/Qwen2.5-3B-MegaScience with Transformers:

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

pipe = pipeline("text-generation", model="MegaScience/Qwen2.5-3B-MegaScience")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("MegaScience/Qwen2.5-3B-MegaScience")
model = AutoModelForCausalLM.from_pretrained("MegaScience/Qwen2.5-3B-MegaScience")
messages = [
    {"role": "user", "content": "Who are you?"},
]
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 significantly improves the model card by:

Adding library_name: transformers to the metadata, which enables the "Use in Transformers" badge and interactive inference widget on the model page.
Including a direct link to the official MegaScience GitHub repository (https://github.com/GAIR-NLP/lm-open-science-evaluation) in the content for easier access to the associated code and evaluation system.
Providing a minimal Python usage example, demonstrating how to load and use the model with the Hugging Face transformers library.

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