Abstract: Recent advancements in Large Vision-Language Models (LVLMs) have demonstrated
significant progress in tackling complex multimodal tasks. Among these
cutting-edge developments, Google's Bard stands out for its remarkable
multimodal capabilities, promoting comprehensive comprehension and reasoning
across various domains. This work presents an early and holistic evaluation of
LVLMs' multimodal abilities, with a particular focus on Bard, by proposing a
lightweight variant of LVLM-eHub, named Tiny LVLM-eHub. In comparison to the
vanilla version, Tiny LVLM-eHub possesses several appealing properties.
Firstly, it provides a systematic assessment of six categories of multimodal
capabilities, including visual perception, visual knowledge acquisition, visual
reasoning, visual commonsense, object hallucination, and embodied intelligence,
through quantitative evaluation of 42 standard text-related visual
benchmarks. Secondly, it conducts an in-depth analysis of LVLMs' predictions
using the ChatGPT Ensemble Evaluation (CEE), which leads to a robust and
accurate evaluation and exhibits improved alignment with human evaluation
compared to the word matching approach. Thirdly, it comprises a mere 2.1K
image-text pairs, facilitating ease of use for practitioners to evaluate their
own offline LVLMs. Through extensive experimental analysis, this study
demonstrates that Bard outperforms previous LVLMs in most multimodal
capabilities except object hallucination, to which Bard is still susceptible.
Tiny LVLM-eHub serves as a baseline evaluation for various LVLMs and encourages
innovative strategies aimed at advancing multimodal techniques. Our project is
