Researchers from Carnegie Mellon University and UC Santa Barbara have introduced REALM, a comprehensive dataset of over 94,000 LLM use cases collected from Reddit and news articles. This groundbreaking resource captures both the diverse applications of LLMs and the demographics of their users, categorizing applications and exploring how users' occupations relate to usage patterns. REALM offers valuable insights into LLM adoption across different domains, providing a foundation for future research on their evolving societal roles.
