adtx-sdxl-01

This is a LyCORIS adapter derived from stabilityai/stable-diffusion-xl-base-1.0.

The main validation prompt used during training was:

AriApartment, KitchIsland, WhiteFlatwareTray, Refrigerator, CoatRackShoeBench, WireShelvingUnitBlack, UtilityCart, ChoppingBoard, CabinetDoor, StepLadder, FakeButcherKnife, WoodenBowl, WireShelvingUnitBlackSmall, GlassdoorCabinet, WoodenSpoon, CabinetDrawer, BlackCeramicMug

Validation settings

• CFG: 4.2
• CFG Rescale: 0.0
• Steps: 20
• Sampler: None
• Seed: 42
• Resolution: 1024x1024

Note: The validation settings are not necessarily the same as the training settings.

You can find some example images in the following gallery:
