Abstract: Playing Large Vision Language Models (LVLMs) in 2023 is trendy among the AI
community. However, the relatively large number of parameters (more than 7B) of
popular LVLMs makes it difficult to train and deploy on consumer GPUs,
discouraging many researchers with limited resources. Imagine how cool it would
be to experience all the features of current LVLMs on an old GTX1080ti (our
only game card). Accordingly, we present Vary-toy in this report, a small-size
Vary along with Qwen-1.8B as the base ``large'' language model. In Vary-toy, we
introduce an improved vision vocabulary, allowing the model to not only possess
all features of Vary but also gather more generality. Specifically, we replace
negative samples of natural images with positive sample data driven by object
detection in the procedure of generating vision vocabulary, more sufficiently
utilizing the capacity of the vocabulary network and enabling it to efficiently
encode visual information corresponding to natural objects. For experiments,
Vary-toy can achieve 65.6% ANLS on DocVQA, 59.1% accuracy on ChartQA, 88.1%
accuracy on RefCOCO, and 29% on MMVet. The code will be publicly available on
the homepage.
