Composing Policy Gradients and Prompt Optimization for Language Model Programs

Noah Ziems, Dilara Soylu, Lakshya A Agrawal +10

Group Relative Policy Optimization (GRPO) has proven to be an effective tool for post-training language models (LMs). However, AI systems are increasingly expressed as modular prog…

Limitations of the LLM-as-a-Judge Approach for Evaluating LLM Outputs in Expert Knowledge Tasks

Annalisa Szymanski, Noah Ziems, Heather A. Eicher-Miller +3

The potential of using Large Language Models (LLMs) themselves to evaluate LLM outputs offers a promising method for assessing model performance across various contexts. Previous r…
