<abstract>While Large Language Models (LLMs) demonstrate remarkable text generation capabilities, they also risk inheriting and perpetuating harmful societal biases present in their vast training data. This study presents a rigorous, large-scale analysis of gender bias in a diverse set of 20 publicly available Spanish generative LLMs, ranging from 760M to 11B parameters. Our methodology utilizes a comprehensive set of specifically designed sentence templates to elicit adjectival descriptions associated with men and women in neutral contexts.
