The model has been trained to use SD to generate hedgehog stickers with simple single colored backgrounds.
Here is one training example which was used:
hedgehogforest, hedgehog cooking on a campfire, fork in hand, cute, sticker
To generate a sticker, you need the trigger word hedgehogforest at the beginning and end your terms with sticker.
The model was trained on the 1.5 pruned emaonly checkpoint.
