Vision Transformers (ViT) apply the transformer architecture—the foundation of LLMs like GPT and BERT—to computer vision tasks. Instead of convolutional layers, ViT divides images into patches and treats them as sequences, applying self-attention to learn relationships. This approach has achieved state-of-the-art results on image classification, object detection, and segmentation. ViT represents a paradigm shift in vision: after decades of CNN dominance, transformers are proving to be more scalable and sample-efficient at large scale. Major organizations (Google, Meta, OpenAI) are building vision systems on ViT; the technology is production-grade.
