What is vit_large_patch14_clip_336.openai?
This model is OpenAI's CLIP implementation using a Vision Transformer architecture, specifically designed for research in zero-shot image classification. It employs a ViT-L/14 Transformer for image encoding and a masked self-attention Transformer for text encoding, trained on a large dataset of image-caption pairs.
Implementation Details
The model architecture consists of a Vision Transformer operating on 14x14 pixel patches at 336x336 resolution. It uses contrastive learning to maximize the similarity between matched image-text pairs, enabling zero-shot classification capabilities.
- Dual-encoder architecture with ViT-L/14 for images and Transformer for text
