Vision Transformers: How ViT Powers Modern Multimodal AI

Vision Transformers changed how AI understands images. Instead of processing pixels with traditional convolutional networks, ViT breaks an image into patch tokens and feeds them into a transformer architecture—creating the foundation for modern vision-language models.

In this video, we explain how Vision Transformers evolved from simple patch-token primitives into the backbone of today’s multimodal AI systems. You’ll learn how image patching works, why positional encoding matters, how 2D-RoPE improves spatial reasoning, and why register tokens help eliminate attention artifacts.

We also compare major pretraining strategies like CLIP, DINOv2, and SigLIP 2, showing how each approach optimizes vision models for semantic matching, dense visual understanding, or stronger multimodal alignment.

Topics covered:

How Vision Transformers tokenize images
Patch size, sequence length, and compute cost
Position embeddings vs 2D-RoPE
