  In the rapidly evolving landscape of artificial intelligence, multi-modal
large language models are emerging as a significant area of interest. These
models, which combine various forms of data input, are becoming increasingly
popular. However, understanding their internal mechanisms remains a complex
task. Numerous advancements have been made in the field of explainability tools
and mechanisms, yet there is still much to explore. In this work, we present a
novel interactive application aimed towards understanding the internal
mechanisms of large vision-language models. Our interface is designed to
enhance the interpretability of the image patches, which are instrumental in
generating an answer, and assess the efficacy of the language model in
grounding its output in the image. With our application, a user can
systematically investigate the model and uncover system limitations, paving the
way for enhancements in system capabilities. Finally, we present a case study
of how our application can aid in understanding failure mechanisms in a popular
large multi-modal model: LLaVA.
