Meaning and Definition
A type of generative artificial intelligence model that creates data (e.g., images, text) by learning to reverse a process of gradually adding noise to data.
In a broader scientific context, any mathematical or computational model that describes the spread or dissemination of substances, ideas, innovations, or information through a medium or population.

FAQ
Frequently Asked Questions
No. 'Diffusion model' is the general class of AI architecture. 'Stable Diffusion' is a specific, famous implementation of a diffusion model created by Stability AI.
No. While image generation is their most famous application, diffusion models can also generate audio, video, and molecular structures.
The core idea is the training process: it learns by destroying data with noise and then figuring out how to reverse that process step-by-step, unlike models that generate in a single step.
Yes. In physics, chemistry, and social sciences, it refers to a model that mathematically describes how particles, heat, or innovations spread through a medium or population.

Diffusion model is usually academic/technical in register.
Diffusion model: in British English it is pronounced /dɪˈfjuːʒən ˈmɒd(ə)l/, and in American English it is pronounced /dɪˈfjuːʒən ˈmɑːd(ə)l/. Tap the audio buttons above to hear it.

Mnemonic
Imagine a picture (DATA) being gradually sprayed with paint (NOISE) until it's just random dots. A DIFFUSION MODEL is like a clever artist who learns to look at the noisy dots and reverse the spraying process to paint the original picture.
Conceptual Metaphor
AI TRAINING IS LEARNING A REVERSAL PROCESS; CREATION IS A JOURNEY FROM CHAOS TO ORDER.
