Title: SPRIG: Improving Large Language Model Performance by System Prompt Optimization

Abstract:
arXiv:2410.14826v3 Announce Type: replace-cross Abstract: Large Language Models (LLMs) have shown impressive capabilities in many scenarios, but their performance depends, in part, on the choice of prompt. Past research has focused on optimizing prompts specific to a task. However, much less attention has been given to optimizing the general instructions included in a prompt, known as a system prompt. To address this gap, we propose SPRIG, an edit-based genetic algorithm that iteratively constru
