One line of work is built by system integration of LLMs with various functioning agents where language acts as general interface (Wu et al., 2023; Gupta & Kembhavi, 2023; Yang et al., 2023b; Liang et al., 2023; Shen et al., 2023; Yang et al., 2023a; Surís et al., 2023), and remarkable success has been demonstrated in such plugin-style frameworks. Another line of work instead explores training LLMs to consume and understand multimodal inputs (Hao et al., 2022; Huang et al., 2023; Chen et al., 2023b) with parameter-efficient tuning (Hu et al., 2022; Alayrac et al., 2022; Li et al., 2023b; Zhang et al., 2023d; Zhu et al., 2023a; Ye et al., 2023) and instruction tuning (Xu et al., 2023; Liu et al., 2023a; Dai et al., 2023). More recently, some approaches have been developed towards visual-interactive multimodal comprehension by precise referring instruction tuning (Zhao et al., 2023a; Peng et al., 2023; Chen et al., 2023a; Zhang et al., 2023f). For cross-modal creation, early works generally tokenize the visual contents into discrete VQ codebooks (van den Oord et al., 2017; Wang et al., 2022; Lu et al., 2023; Diao et al., 2023; Yu et al., 2023a). Recent works instead explore incorporating MLLMs for image synthesis using text-to-image models such as Stable Diffusion, and the objective is to generate conditional embeddings that align pretrained CLIP text (i.e., CLIP) or CLIP variant embeddings (Koh et al., 2023; Ge et al., 2023; Sun et al., 2023a;b).
