Using PhotoMaker to personalize image generation

You can use PhotoMaker to personalize generated images with your own ID.

NOTE, currently PhotoMaker ONLY works with SDXL (any SDXL model files will work).

Download PhotoMaker model file (in safetensor format) here. The official release of the model file (in .bin format) does not work with stablediffusion.cpp.

  • Specify the PhotoMaker model path using the --stacked-id-embd-dir PATH parameter.
  • Specify the input images path using the --input-id-images-dir PATH parameter.
    • input images must have the same width and height for preprocessing (to be improved)

In prompt, make sure you have a class word followed by the trigger word "img" (hard-coded for now). The class word could be one of "man, woman, girl, boy". If input ID images contain asian faces, add Asian before the class word.

Another PhotoMaker specific parameter:

  • --style-ratio (0-100)%: default is 20 and 10-20 typically gets good results. Lower ratio means more faithfully following input ID (not necessarily better quality).

Other parameters recommended for running Photomaker:

  • --cfg-scale 5.0
  • -H 1024
  • -W 1024

If on low memory GPUs (<= 8GB), recommend running with --vae-on-cpu option to get artifact free images.

Example:

bin/sd -m ../models/sdxlUnstableDiffusers_v11.safetensors  --vae ../models/sdxl_vae.safetensors --stacked-id-embd-dir ../models/photomaker-v1.safetensors --input-id-images-dir ../assets/photomaker_examples/scarletthead_woman -p "a girl img, retro futurism, retro game art style but extremely beautiful, intricate details, masterpiece, best quality, space-themed, cosmic, celestial, stars, galaxies, nebulas, planets, science fiction, highly detailed" -n "realistic, photo-realistic, worst quality, greyscale, bad anatomy, bad hands, error, text" --cfg-scale 5.0  --sampling-method euler -H 1024 -W 1024 --style-ratio 10 --vae-on-cpu -o output.png
