description Overview

Stable Diffusion 1.5

Stable Diffusion 1.5 is an open-weight text-to-image model released by Runway in October 2022, building on the Stable Diffusion project associated with Stability AI and researchers at LMU Munich. It uses latent diffusion, generating images by gradually removing noise from a compressed representation guided by a text prompt. Working in that compressed space helps reduce computing demands compared w...

Imagen

Imagen is a text-to-image diffusion model introduced by Google Research in 2022. The model is distinguished by its architecture, which combines a frozen large language model for text processing with a cascaded diffusion model for image generation. This design allows Imagen to produce highly photorealistic images that accurately reflect complex textual prompts. The model was initially presented in...
