Apple Research is generating images with a forgotten AI technique

Today, most generative image models basically fall into two main categories: diffusion models, like Stable Diffusion, or autoregressive models, like OpenAI’s GPT-4o. But Apple just released two papers that show how there might be room for a third, forgotten technique: Normalizing Flows. And with a dash of Transformers on top, they might be more capable than previously thought.

First things first: What are Normalizing Flows?

Normalizing Flows (NFs) are a type of AI model that works…
