Model Card for qwen-3-4b-thinking-r1-st-medium

This model is a fine-tuned version of LlameUser/qwen-3-4b-thinking-r1-st-easy. It has been trained using TRL.

Quick start

from transformers import pipeline

question = "If you had a time machine, but could only go to the past or the future once and never return, which would you choose and why?"
generator = pipeline("text-generation", model="LlameUser/qwen-3-4b-thinking-r1-st-medium", device="cuda")
output = generator([{"role": "user", "content": question}], max_new_tokens=128, return_full_text=False)[0]
print(output["generated_text"])

Training procedure

This model was trained with GRPO, a method introduced in DeepSeekMath: Pushing the Limits of Mathematical Reasoning in Open Language Models.
