**SigLIP 2** is a multilingual vision–language encoder that extends the original SigLIP training objective with captioning, self-distillation, masked prediction, and improved data curation for stronger semantic understanding, localization, and dense visual representations.

# SigLIP2-Base-Patch16-224

This model uses the **SigLIP 2 Base-Patch16-224x224** variant, based on a ViT-Base vision encoder with **16×16 image patches** and approximately **86M parameters**. It is well suited for zero-shot image classification, image–text retrieval, and as a vision encoder for VLMs and downstream vision tasks.
