What is ViT-B-16-SigLIP2-256?
ViT-B-16-SigLIP2-256 is an advanced vision-language model that builds upon the original SigLIP architecture, introducing improved capabilities for multilingual understanding, semantic comprehension, and visual localization. The model is specifically designed for zero-shot image classification and contrastive image-text learning tasks.
Implementation Details
The model implements a Vision Transformer architecture with a 16x16 patch size and leverages the sigmoid loss function for enhanced language-image pre-training. It has been converted from original JAX checkpoints to be compatible with the OpenCLIP framework, making it more accessible for widespread use.
