About Stable Diffusion
Stable Diffusion is a latent text-to-image diffusion model capable of generating photo-realistic images given any text input. It uses a fixed, pretrained CLIP ViT-L/14 text encoder and was fine-tuned on the laion-aesthetics v2 5+ dataset at 512x512 resolution. The model is open source under the CreativeML OpenRAIL M license and can be run using the Hugging Face Diffusers library, supporting PyTorch and JAX/Flax frameworks. The v1-4 checkpoint was initialized from v1-2 and further fine-tuned for 225k steps with 10% text-conditioning dropout to improve classifier-free guidance sampling.

FAQ
What is Stable Diffusion v1-4?
It is a latent text-to-image diffusion model fine-tuned from v1-2 on the laion-aesthetics v2 5+ dataset at 512x512 resolution, using a CLIP ViT-L/14 text encoder.
How can I run Stable Diffusion?
Use the Hugging Face Diffusers library: install diffusers, transformers, and scipy, then load the model with StableDiffusionPipeline and run it on a GPU with torch.float16 for memory efficiency.
What license does Stable Diffusion use?
The model is released under the CreativeML OpenRAIL M license, adapted from BigScience and the RAIL Initiative.
What hardware is recommended?
A GPU with at least 4GB VRAM is recommended. For less than 4GB, use float16 precision and enable attention slicing.
