The DDIM sampler, or Denoising Diffusion Implicit Models sampler, is one of the most popular samplers for text-to-image diffusion models. It is a fast and efficient sampler that can generate high-quality images in a reasonable amount of time.

DDIM is known for:

The DDIM sampler works by approximating the image at each step of the diffusion process using a combination of the previous image, the noise that was added to the previous image, and the desired image. This allows the sampler to generate images that are both accurate and visually appealing.
