Rohan Paul Posts on NPO Prompt Optimization Method

Rohan Paul tweeted that prompt optimization may depend more on teacher quality and feedback than on elaborate search algorithms. He described a paper testing NPO, which maintains one prompt lineage and has a teacher model revise it using recent rollout traces and rewards. The post contrasts this with GEPA and includes a screenshot of the arXiv paper abstract. Paul is a Bengaluru-based machine learning engineer who writes an AI newsletter.
