Interestingly, data and architectural improvements seem to mitigate the negative impact of data balancing on performance; e. g. applying M4 to SigLIP-B/16 with data quality filters improves COCO image-to-text retrieval @5 from 86% (without data balancing) to 87% and ImageNet 0-shot classification from 77% to 77. 5%!

We further analyze the effect of the model architecture and scale, as well as the pretraining data on the representation quality, and find that captioning exhibits the same or better scaling behavior along these axes.

With 3T, we propose a more flexible strategy that allows the image tower to benefit from both pretrained embeddings and contrastive training.

A key finding is that a small decoder learned on top of a frozen pretrained encoder works surprisingly well.
