Two new research papers explore the challenge of evaluating how well large language models (LLMs) can simulate human personalities. The first paper introduces PRISM, a framework grounded in Systemic Functional Linguistics, which breaks down persona fidelity into task framing, interpersonal stance, and linguistic style for more accurate and interpretable evaluation. The second paper benchmarks various LLMs against a large dataset of human personality surveys, finding that while some local models fail to align with human responses, frontier models can successfully emulate personality traits, suggesting their potential for creating more realistic non-player characters in video games.
