Large language models (LLMs) offer new opportunities to study human behavior, yet their rapidly evolving nature poses challenges for research rigor. GUIDE-LLM provides a consensus-based reporting checklist to improve transparency, reproducibility, and ethical accountability across behavioral and social science research. In particular, GUIDE-LLM supports researchers in clearly describing how LLMs were used, why specific methodological choices were made, and what steps were taken to ensure responsible research practices.
