• Stable Diffusion 2.1. https://huggingface.co/stabilityai/stable-diffusion-2-1
• Optimized for speed with AI Template - very fast, now supports all input shapes up to 1024x1024
• fp16
• Can run on A100 GPUs, but not T4, due to lack of AI Template support

• Stable Diffusion 1.5. https://huggingface.co/runwayml/stable-diffusion-v1-5
• Optimized for speed with AI Template - very fast, now supports all input shapes up to 1024x1024
• Can run on A100 GPUs, but not T4, due to lack of AI Template support

• Stable Diffusion 2.1. https://huggingface.co/stabilityai/stable-diffusion-2-1
• Integrates the CompVis/stable-diffusion-safety-checker to filter NSFW content.
• More Schedulers - DDIM, K_EULER, DPMSolverMultistep, K_EULER_ANCESTRAL, PNDM, KLMS

• Stable Diffusion 2.0. https://huggingface.co/stabilityai/stable-diffusion-2
• Removes PNDM, KLMS, K_EULER_ANCESTRAL from scheduler choices.
• init_image has been removed and moved to a separate model: https://replicate.com/stability-ai/stable-diffusion-img2img
• mask has been removed and moved to a separate model: https://replicate.com/stability-ai/stable-diffusion-inpainting

• Add negative prompt.

• Support for more image sizes.
• Support for arbitrary number of outputs up to 10.
• Fix multiple outputs not working.

• Use the img2img pipelines from diffusers, which produces better quality output when using the init_image input.

Stable Diffusion 1.5. The checkpoint was initialized with the weights of the Stable-Diffusion-v1-2 checkpoint and subsequently fine-tuned on 595k steps at resolution 512x512 on “laion-aesthetics v2 5+” and 10% dropping of the text-conditioning to improve classifier-free guidance sampling.

Stable Diffusion 1.4. The checkpoint was initialized with the weights of the Stable-Diffusion-v-1-2 checkpoint and subsequently fine-tuned on 225k steps at resolution 512x512 on “laion-aesthetics v2 5+” and 10% dropping of the text-conditioning to improve classifier-free guidance sampling.
