The rapid evolution of large language models such as GPT-4 Turbo represents an impactful paradigm shift in digital interaction and content engagement. While these models encode vast amounts of human-generated knowledge and excel in processing diverse data types, recent research shows that they often face the challenge of accurately responding to specific user intents, leading to increased user dissatisfaction. Based on a fine-grained intent taxonomy and intent-based prompt reformulations, we analyze (1) the quality of intent recognition and (2) user satisfaction with answers from intent-based prompt reformulations for two recent ChatGPT models, GPT-3.5 Turbo and GPT-4 Turbo. The results reveal that GPT-4 outperforms GPT-3.5 on the recognition of common intents, but is conversely often outperformed by GPT-3.5 on the recognition of less frequent intents. Moreover, whenever the user intent is correctly recognized, while users are more satisfied with the answers to intent-based reformulations of GPT 4 compared to GPT-3.5, they tend to be more satisfied with the answers of the models to their original prompts compared to the reformulated ones. Finally, the study indicates that users can quickly learn to formulate their prompts more effectively, once they are shown possible reformulation templates.
