Stable Diffusion

Stable Diffusion is a latent text-to-image diffusion model capable of generating photo-realistic images given any text input. This model card gives an overview of all available model checkpoints. For more in-detail model cards, please have a look at the model repositories listed under Model Access.

Stable Diffusion Version 1

For the first version 4 model checkpoints are released. Higher versions have been trained for longer and are thus usually better in terms of image generation quality then lower versions. More specifically:

  • stable-diffusion-v1-1: The checkpoint is randomly initialized and has been trained on 237,000 steps at resolution 256x256 on laion2B-en. 194,000 steps at resolution 512x512 on laion-high-resolution (170M examples from LAION-5B with resolution >= 1024x1024).
  • stable-diffusion-v1-2: The checkpoint resumed training from stable-diffusion-v1-1. 515,000 steps at resolution 512x512 on "laion-improved-aesthetics" (a subset of laion2B-en, filtered to images with an original size >= 512x512, estimated aesthetics score > 5.0, and an estimated watermark probability < 0.5. The watermark estimate is from the LAION-5B metadata, the aesthetics score is estimated using an improved aesthetics estimator).
  • stable-diffusion-v1-3: The checkpoint resumed training from stable-diffusion-v1-2. 195,000 steps at resolution 512x512 on "laion-improved-aesthetics" and 10 % dropping of the text-conditioning to improve classifier-free guidance sampling
  • stable-diffusion-v1-4: The checkpoint resumed training from stable-diffusion-v1-2. 195,000 steps at resolution 512x512 on "laion-improved-aesthetics" and 10 % dropping of the text-conditioning to improve classifier-free guidance sampling.
  • stable-diffusion-v1-4 Resumed from stable-diffusion-v1-2.225,000 steps at resolution 512x512 on "laion-aesthetics v2 5+" and 10 % dropping of the text-conditioning to improve classifier-free guidance sampling.

Model Access

Each checkpoint can be used both with Hugging Face's 🧨 Diffusers library or the original Stable Diffusion GitHub repository. Note that you have to "click-request" them on each respective model repository.
