Another SDXL LoRA for more explicit content, this time it is for dildos and sex toys. This was a difficult concept for SD 1.5 to master, so we will see how XL can handle it.

• v0.3:

  • Better support for anime and cartoon/render/pixar styles.

  • More variety of lingerie and clothing, not always with breasts out.

  • Works at 0.8-1.0 strength, not as overtrained.

• v0.2:

  • Epoch 93 and 99 are both pretty good, using 0.7 - 0.8 strength.

• v0.1:

  • In general, I think epoch 74 has the best results, using about 0.75 strength.

Learned Keywords:

• primary:

  • dildo for v0.3

  • sexl_dildo for v0.1 and v0.2

Training Method:

Testing this method: https://civarchive.com/articles/1771. Versions 0.1 and 0.2 used the 100 epoch method with 2e-05 learning rate.

• v0.3:

  • 1458 source images (> 768 in shortest dimension)

  • 1588 random crops (1024x1024)

  • 1410 remaining after curation

    • up to 12 crops per source

    • downscaled shortest dimension to 1024

    • deduplicated with resnet 18, cosine similarity, 0.925 threshold

    • deleted partial and out of frame

    • no watermarks

  • automated captions with WD 1.4, threshold 0.45

    • incorrect tags removed

  • 2 repeats

  • 8 batch size

  • 100 epochs

  • 32 dim/32 alpha

  • AdamW8bit with constant

  • 2e-05 learning rate for both text encoder and UNet

  • shuffle captions

  • caption dropout rate 0.05

  • stop text encoder training after 30% (still not sure if this feature is implemented)

• v0.2:

  • 344 source images

  • 287 after deduplication and resize

  • 1087 random crops

  • 806 remaining after curation

    • same method as v0.1

  • automation captions with WD 1.4, threshold 0.6

    • lightly curated, incorrect tags removed

  • 3 repeats

  • 8 batch size

  • 100 epochs

  • 32 dim/32 alpha

  • AdamW8bit with constant

  • 2e-05 learning rate for both text encoder and UNet

  • shuffle captions

• v0.1:

  • about 500 source images (> 1024x1024)

  • about 1000 random crops (1024x1024)

  • 440 remaining after curation

    • deduplicated with resnet 18, cosine similarity, 0.9 threshold

    • deleted partial and out of frame

    • no watermarks

  • 1 repeats

  • 8 batch size

  • 100 epochs (models around 45-50 and 70-75 were best)

  • 32 dim/32 alpha

  • AdamW8bit with constant

  • 2e-05 learning rate for both text encoder and UNet

I am happy to share the data set but do not have a good place for hosting those.

• v0.3:

  • Includes more lingerie and clothing

• v0.2:

  • Next time I need to indicate the color of the dildo in the caption and include more of the image poses.

• v0.1:

  • Next time I think I will try removing the sexl_dildo keyword and specializing the existing dildo token.
