• Abstract: An essential topic for multimodal large language models (MLLMs) is aligning vision and language concepts at a finer level. In particular, we devote efforts to encoding visual referential information for tasks such as referring and grounding. Existing methods, including proxy encoding and geometry encoding, incorporate additional syntax to encode the object's location, bringing extra burdens in training MLLMs to communicate between language and vision. This study presents ClawMachine, offering a new methodology that notates an entity directly using the visual tokens. It allows us to unify the prompt and answer of visual referential tasks without additional syntax. Upon a joint vision-language vocabulary, ClawMachine unifies visual referring and grounding into an auto-regressive format and learns with a decoder-only architecture. Experiments validate that our model achieves competitive performance across visual referring and grounding tasks with a reduced demand for training data. Additionally, ClawMachine demonstrates a native ability to integrate multi-source information for complex visual reasoning, which prior MLLMs can hardly perform without specific adaptions.

  We propose a new pretraining paradigm for Large Language Models (LLMs) to enhance their visual comprehension capabilities. Specifically, we design a dynamically learnable prompt token pool and employ the Hungarian algorithm to replace part of the original visual tokens with the most relevant prompt tokens. We present a new foundation model called Croc, which achieves new state-of-the-art performance on massive vision-language benchmarks.

  multimodal large language models (MLLMs) have made significant strides by training on vast high-quality image-text datasets.

The resulting visual tokens encompass high-level semantics worthy of a word and also support dynamic sequence length varying from the image. This unification empowers LaVIT to serve as an impressive generalist interface to understand and generate multi-modal content simultaneously.
