The survey highlights the approaches taken by various MLLMs, such as SPHINX-X, ALLaVA, VILA's research, and others, in generating text-based or multimodal instruction-following data with a limited number of hand-annotated samples. These MLLMs leverage diverse and fine-grained datasets to prompt GPT-4V with marked images and tailored domain-specific guidelines to generate captions with image overviews, regional details, and object relationship insights. The paper also discusses their performance on a range of scenarios vis-a-vis other multimodal tasks.

In addition, the authors present a detailed comparison of the effectiveness of 22 MLLMs across 14 well-established Visual Language (VL) benchmarks, and they incorporate a comparison of results from 13 prominent and larger MLLMs. The analysis reveals the comprehensive evaluation of efficient MLLMs across VL benchmarks and the relative performance compared to larger MLLMs.

The paper further expands the application of efficient MLLMs to incorporate several downstream tasks, including medical analysis, document understanding, and video comprehension. Notably, the mixture of Expert Tuning has effectively enhanced the performance of general MLLMs with fewer parameters, and models such as MoE-TinyMed and LLaVA-Rad have demonstrated rapid performance, showcasing superior efficiency and effectiveness in private settings.

Furthermore, the paper discusses efficient MLLMs' challenges in processing extended-context multimodal information and their limitations to accepting single images. It also emphasizes expanding the models' scope to accommodate a wider array of input modalities and augmenting their generative capacities to bolster their multifunctionality and widen their applicability.

Overall, the survey paper provides a detailed overview of efficient Multimodal Large Language Models, covering their timeline, research state, applications, limitations, and future directions. It encompasses a wide range of efficient structures and strategies and their applications, contributing to a comprehensive understanding of the advancements in the field of efficient MLLMs.
