Diffusion transformers are the key behind OpenAI’s Sora — and they’re set to upend GenAI

OpenAI’s Sora, which can generate videos and interactive 3D environments on the fly, is a remarkable demonstration of the cutting edge in GenAI — a bonafide milestone. But curiously, one of the innovations that led to it, an AI model architecture colloquially known as the diffusion transformer, arrived on the AI research scene years ago. […]
