PersonaVLM: Long-Term Personalized Multimodal LLMs (CVPR 2026)

🎉 News: Our paper "PersonaVLM: Long-Term Personalized Multimodal LLMs" is accepted to CVPR 2026!

🌟 Introduction

PersonaVLM is an innovative personalized multimodal agent framework designed for long-term personalization. It transforms a general-purpose MLLM into a personalized assistant by integrating three key capabilities:

1. Remembering: Proactively extracts and summarizes multimodal memories into a personalized database.
2. Reasoning: Conducts multi-turn reasoning by retrieving relevant memories from a multi-type memory architecture (core, semantic, episodic, and procedural).
3. Response Alignment: Infers the user's evolving personality using a Momentum-based Personality Evolving Mechanism (PEM) to ensure aligned outputs.

📊 Persona-MME Benchmark

We establish Persona-MME, a comprehensive benchmark comprising over 2,000 curated interaction cases across 14 fine-grained tasks to assess long-term MLLM personalization.
