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

Libraries

How to use Scale-or-Reason/Qwen2.5-3B-ift with Transformers:

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

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

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("Scale-or-Reason/Qwen2.5-3B-ift")
model = AutoModelForCausalLM.from_pretrained("Scale-or-Reason/Qwen2.5-3B-ift")
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 improves the model card by explicitly linking to the project page on Hugging Face: https://huggingface.co/when-does-reasoning-matter. This provides a central hub for related models and datasets from the paper.

The paper link remains the arXiv link as per guidelines, and no license is added due to lack of explicit evidence in the provided context.
