### What are Stable Diffusion Models?

Stable diffusion models are a class of generative models used primarily for image synthesis, based on the principles of diffusion processes. They are designed to generate high-quality, diverse images by gradually transforming a simple initial noise distribution into a more complex and structured output, typically resembling real-world data.

### What's the difference between the original models and their 8-bit / 6-bit / 4.5-bit quantized counterparts?

6-bit and 4.5-bit model versions are three times lighter than the originals, saving significant memory. \
\
They can run on devices with limited RAM, including iPhone 12-13, iPads with the A15 chip, and older Macs that may struggle with the original models. \
\
They are only available for macOS 14 and iOS 17 or later.
