New image tokenization methods boost MLLM performance

By PulseAugur Editorial · Summary by gemini-2.5-flash-lite from 2 sources

Two new research papers propose novel methods for tokenizing images to improve multimodal large language models (MLLMs). The first paper, VFMTok, uses a frozen vision foundation model as a tokenizer, achieving significant improvements in synthesis quality and token efficiency. The second paper, DiVT, clusters patch embeddings into semantic units, making visual tokens more compatible with LLMs and reducing memory costs and latency. AI

    Vision Foundation Models as Generalist Tokenizers for Image Generation

    In this work, we explore the largely unexplored direction of building a generalist image tokenizer directly on top of a frozen vision foundation model (VFM). To build this tokenizer, we utilize a frozen VFM as the encoder and introduce two key innovations: (1) a region-adaptive q…

    A More Word-like Image Tokenization for MLLMs

    Modern multimodal large language models (MLLMs) typically keep the language model fixed and train a visual projector that maps the pixels into a sequence of tokens in its embedding space, so that images can be presented in essentially the same form as text. However, the language …
