REINFORCE: Simple Online RL for LLMs

This article discusses the REINFORCE algorithm as a simplified approach to online reinforcement learning for large language models (LLMs), offering an alternative to the more complex Proximal Policy Optimization (PPO). The core idea is to leverage REINFORCE's relative simplicity for faster experimentation and easier implementation, potentially unlocking the benefits of online RL without the significant overhead of PPO. The article likely explores the trade-offs between simplicity and performance, and the specific scenarios where REINFORCE might be a more suitable choice for fine-tuning LLMs. It's a valuable contribution for practitioners seeking practical RL solutions for LLMs.
