Awesome Personalization in MLLMs

The most comprehensive survey and frontier tracking repository for personalized LLMs and MLLMs, covering personalized memory, alignment, retrieval, and evaluation.

Project Page | 中文 README

📖 Overview

Personalized LLMs and MLLMs aim to move beyond one-size-fits-all assistants. Instead of only optimizing for average human preference, they need to model a specific user: long-term goals, evolving preferences, implicit personas, multimodal context, and when personalization should or should not be applied.

This repository tracks papers, benchmarks, datasets, and systems around four connected research directions:

DirectionCore Question
Personalized MemoryWhat should an agent store, update, retrieve, compress, and forget?
Personalized AlignmentHow can a model adapt to individual preferences, personalities, and contexts?
Personalized RetrievalHow should systems select the right user context, memory, and evidence?
Personalized EvaluationHow do we evaluate long-term, dynamic, implicit, and multimodal personalization?
