Diffusion Model
A type of generative AI model that creates images (or video, audio) by gradually removing noise from a random starting point. Stable Diffusion, FLUX, and DALL-E are all diffusion models. Running diffusion models locally requires a decent GPU but less VRAM than LLMs — most image generators work well with 8–12 GB VRAM. Speed scales with GPU compute power, so faster cards produce images in seconds rather than minutes.
