DAPO-8B

Model Card for DAPO-8B

This model is a fine-tuned version of deepseek-ai/DeepSeek-R1-Distill-Llama-8B on the knoveleng/open-rs dataset. 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="kangdawei/DAPO-8B", 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 DAPO, a method introduced in DAPO: An Open-Source LLM Reinforcement Learning System at Scale.
