Stable Diffusion v2-1-base Model Card

This model was generated by Hugging Face using Apple’s repository which has ASCL. This version contains 2-bit linearly quantized Core ML weights for iOS 17 or macOS 14. To use weights without quantization, please visit this model instead.

This model card focuses on the model associated with the Stable Diffusion v2-1-base model.

This stable-diffusion-2-1-base model fine-tunes stable-diffusion-2-base (512-base-ema.ckpt) with 220k extra steps taken, with punsafe=0.98 on the same dataset.

These weights here have been converted to Core ML for use on Apple Silicon hardware.

There are 4 variants of the Core ML weights:

coreml-stable-diffusion-2-1-base
β”œβ”€β”€ original
β”‚   β”œβ”€β”€ compiled              # Swift inference, "original" attention
β”‚   └── packages              # Python inference, "original" attention
└── split_einsum
    β”œβ”€β”€ compiled              # Swift inference, "split_einsum" attention
    └── packages              # Python inference, "split_einsum" attention

There are also two zip archives suitable for use in the Hugging Face demo app and other third party tools:

  • coreml-stable-diffusion-2-1-base-palettized_original_compiled.zip contains the compiled, 6-bit model with ORIGINAL attention implementation.
  • coreml-stable-diffusion-2-1-base-palettized_split_einsum_v2_compiled.zip contains the compiled, 6-bit model with SPLIT_EINSUM_V2 attention implementation.
