Backend V1


Backend V1 is a complete rewrite of the original image inference and processing pipeline. Here are some of the improvements:

  1. Hi-Res (aka Super-Resolution Details) for SDXL is available.
  2. Faster.
  3. Better handling of loading multiple LoRAs.
  4. DPM++/Karras and DPM++SDE/Karras better results, especially with SDXL.
  5. Civit results should be easy to reproduce.

Features still pending implementation for Backend V1:

  1. TCD sampler
  2. FaceID with --faceid_portrait
  3. --fix_bindi

As this is still in BETA stages, we encourage you to report any issues you may encounter using the support email.
