A new study published on arXiv explores how different tones in prompts can affect the performance of Large Language Models (LLMs) on objective multiple-choice questions. Researchers tested four LLMs, including ChatGPT-4o, ChatGPT-5-nano, Gemini 2.5 Flash, and Gemini 2.5 Flash Lite, using datasets with varied tones. The findings indicate that tonal effects are systematic but highly dependent on the specific model, with some models showing significant accuracy swings across different tones. The study also identified subject-level differences in tone sensitivity and proposed a routing framework to explain these variations, cautioning users about the assumption of tone-robust reliability in LLM deployments.
