A new study published on arXiv explores the capabilities of Large Language Model (LLM) agents in simulating social media reactions. Researchers found that LLM agents, particularly GPT-5.5 Pro, can achieve high accuracy in predicting user reactions when provided with comprehensive profiles. However, accuracy significantly drops when profile information is reduced, highlighting the importance of detailed user data for effective simulation. The study also notes that LLMs demonstrate zero-shot generalization capabilities that traditional classifiers lack, but their effectiveness is diminished for posts lacking direct links to user profiles.
