Reinforcement Pre-Training (RPT) By Microsoft Explained

In this video we dive into a recent Microsoft's paper titled Reinforcement Pre-Training (RPT). The paper introduces a mechanism to scale reinforcement learning (RL) training data to that used for the pre-training stage of large language models (LLMs). While in standard LLM pre-training, we use a next-token prediction (NTP) objective, RPT introduces next-token reasoning, transforming each token prediction into a reasoning task. Next-token reasoning is then used for RL training with GRPO. We covered GRPO in depth here: GRPO full review -https://aipapersacademy.com/deepseekmath-grpo/ GRPO vi…
