What papers say
Verbatim critique sentences, each from a paper that cites PPO (Proximal Policy Optimization) as a baseline.
Foundational approaches like Reinforcement Learning from Human Feedback (RLHF), typically implemented via Proximal Policy Optimization (PPO), are powerful but suffer from high computational overhead and hyperparameter sensitivity.
What to use instead
Recent methods in the same sub-problem, not yet superseded in the knowledge base — arXiv benchmark leaders, not vetted production recommendations.
