description Overview

Stable Diffusion 2.1

Stable Diffusion 2.1 is an open-weight text-to-image latent diffusion model released by Stability AI in late 2022. As a refinement of the Stable Diffusion 2.0 architecture, it utilizes the OpenCLIP-ViT/H text encoder to better process complex text prompts. The model natively generates images at higher resolutions of 768x768 pixels and was trained on filtered subsets of the LAION-5B dataset. It is...

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...
