Modeling Complex Behaviors: Multi-Personality Composition and Dynamic Switching in Vision-Language Models

arXiv:2606.11074v1 Announce Type: new Abstract: With the widespread deployment of Multimodal Large Language Models (MLLMs) in social interaction, understanding and controlling their behavior under complex personality conditions is essential. This paper introduces explicit personality conditioning and establishes a systematic evaluation framework encompassing single-personality induction, multi-personality induction, and personality switching. Experiments show that personality induction improves image captioning performance but can impair performance on tasks requiring precise reasoning, such a

Why this matters
Why now

The proliferation of Multimodal Large Language Models in social interaction necessitates advanced control over their behavior and personalities to prevent misuse and enhance human-AI interaction.

Why it’s important

Controlling and inducing specific personalities in MLLMs is crucial for developing safe, reliable, and contextually appropriate AI, impacting both application design and ethical guidelines.

What changes

The ability to explicitly condition and dynamically switch personalities in MLLMs introduces a new layer of complexity and control over AI behavior, transitioning them from static entities to adaptable social agents.
