Researchers have developed a method to generate multimodal behaviors for socially interactive agents, aiming to calibrate user trust based on an agent's capabilities and benevolence. The study utilized GPT-5.4 to produce verbal, vocal, gestural, and facial expressions, demonstrating coherence across modalities. While the generated behaviors aligned with intended trustworthiness levels, the research also identified a tendency for LLMs to perpetuate gender stereotypes when gender was specified in prompts, associating male agents with higher ability and female agents with higher benevolence.
