Multi-modal Large Language Models (MLLMs) have demonstrated impressive
instruction abilities across various open-ended tasks. However, previous
methods primarily focus on enhancing multi-modal capabilities. In this work, we
introduce a versatile multi-modal large language model, mPLUG-Owl2, which
effectively leverages modality collaboration to improve performance in both
text and multi-modal tasks. mPLUG-Owl2 utilizes a modularized network design,
with the language decoder acting as a universal interface for managing
different modalities. Specifically, mPLUG-Owl2 incorporates shared functional
modules to facilitate modality collaboration and introduces a modality-adaptive
module that preserves modality-specific features. Extensive experiments reveal
that mPLUG-Owl2 is capable of generalizing both text tasks and multi-modal
tasks and achieving state-of-the-art performances with a single generic model.
Notably, mPLUG-Owl2 is the first MLLM model that demonstrates the modality
collaboration phenomenon in both pure-text and multi-modal scenarios, setting a
pioneering path in the development of future multi-modal foundation models.

通过引入模态协作，mPLUG-Owl2 多模态大型语言模型在文本和多模态任务中实现了卓越的性能，并且是首个在纯文本和多模态场景中展示模态协作现象的 MLLM 模型，为未来多模态基础模型的发展开辟了先河。
