What is siglip-base-patch16-512?

SigLIP (Sigmoid Loss for Language Image Pre-Training) is an advanced multimodal model that builds upon CLIP's architecture while introducing a novel sigmoid loss function. This base-sized model, trained on WebLI dataset, operates at 512x512 resolution and is specifically designed for vision-language tasks. Unlike traditional CLIP models, SigLIP's innovative loss function works directly with image-text pairs without requiring global similarity normalization.

Implementation Details

The model processes images by resizing them to 512x512 pixels and normalizing across RGB channels with mean and standard deviation of 0.5. Text inputs are tokenized and padded to 64 tokens. Training was conducted on 16 TPU-v4 chips over three days, resulting in a model with 204M parameters.
