Researchers have conducted a large-scale analysis of how minor changes in prompt wording affect the performance of large language models (LLMs). They discovered a scaling law where higher average task performance correlates with greater robustness to prompt variations. The study identified domain-specific terminology and explicit action directives as key linguistic drivers for this robustness, helping to constrain the model's interpretation and lead to more deterministic outputs. Based on these findings, an automated agent was developed to restructure prompts, which reduced performance variance by over 40% in code generation tasks while maintaining or improving mean performance.
