There was research on LLMs training and distillation that if two models have a similar architecture (probably the case for Xai) the "master" model will distill knowledge to the model even if its not in the distillation data. So they probably need to train a new model from scratch.

(sorry i don't remember the name but there was an example with a model liking howl to showcase this)

You should read the 6th page of the paper (and page 5 for architecture breakdown), they show that they are compressing the vision tokens with convolution to keep a strong semantic understanding and keep a small amount of tokens.

But I think it's still experimentall.

Vision tokens are a good compression medium because with one vision token you have one vector of N elements, but with textual tokens you have M vectors of N elements, because one vision token represent multiple pixels (and possibly multiple words). This is why its a good compression medium for compute.

It will never be as precise as textual tokens but it can be really good as they show in the paper.

LLMs are compute heavy with quadratic scaling (in compute) per tokens. They are trying to compress text tokens into visual tokens with their VLM.

Maybe they would render texts to an image before tokenizing to reduce the compute cost.
