A new paper from Hugging Face highlights a significant gap between how large language models (LLMs) perform personalization using synthetic data versus real human interactions. The research found that LLMs struggle to accurately extract user attributes, match relevant attributes to new prompts, and generate personalized responses that humans find genuinely helpful. Human evaluations revealed that LLMs often over-personalize and that automated reward models have only a modest correlation with human quality judgments, underscoring the need to re-center human data in LLM personalization.
