Open-Reasoner-Zero: An Open Source Approach to Scaling Up Reinforcement Learning on the Base Model

Summary

Open-Reasoner-Zero (ORZ) is introduced as an open-source project focused on large-scale reinforcement learning for reasoning in large language models. The authors demonstrate that a simple approach using vanilla PPO and a basic reward function can effectively scale up reasoning abilities, even outperforming a prior method (DeepSeek-R1-Zero) on a benchmark while using significantly…
