Researchers at the USC Information Sciences Institute have conducted a study examining the impact of small changes to prompts on the accuracy of responses from large language models like ChatGPT. The findings, published on the preprint server arXiv, revealed that even subtle variations in prompts can significantly influence the predictions made by these models.
The study focused on four categories of prompt variations:
– Requesting responses in specific output formats
– Making minor perturbations to the prompt itself, such as adding extra spaces or polite phrases
– Using jailbreaks to bypass content filters
– Offering tips for a perfect response
The researchers tested these variations across 11 benchmark text classification tasks, including toxicity classification, grammar evaluation, humor detection, and mathematical proficiency. They found that changes in prompt structure and presentation could have a notable impact on the accuracy of model predictions.
Interestingly, the researchers discovered that certain variations, such as not specifying a format, led to the highest overall accuracy. Additionally, they observed that different tip amounts did not significantly affect response accuracy. However, jailbreaks, even seemingly harmless ones, resulted in notable accuracy loss.
The study hinted at the potential role of confusion in prompting the LLM to change its predictions. The researchers speculated that the relationship between the inputs the model is trained on and its subsequent behavior could be a contributing factor.
In conclusion, the researchers suggest that keeping prompts simple may yield the best results overall. They emphasize the need for LLMs that are resilient to prompt variations, ensuring consistent responses across different formatting changes and perturbations. Future work will focus on gaining a deeper understanding of why responses change and improving model performance in the face of prompt variations.
