Reisa portrait Reisa V Reisa pose

Unfortunately the model frequently struggles with Reisa's halo.

Usage

Use any or all of these tags to summon Reisa: reisa, halo, low twintails, pink hair, purple eyes, star hair ornament

  • Hair and eye tags are optional.

She likes to make her :d expression by default. I included images tagged with other expressions, so you should be able to change it, but if not try adding :d to the negative prompt.

For her normal outfit: school uniform, grey shirt, blue jacket, pleated skirt, striped socks, backpack, sneakers

Training

Exact parameters are provided in the accompanying JSON files.

  • Trained on a set of 89 images
    • 13 repeats
    • 3 batch size, 4 epochs
    • (89*13) / 3 * 4 = 1543 steps
  • 0.0743 loss
  • 768x768 training resolution
  • constant_with_warmup scheduler instead of cosine
  • Initially tagged with WD1.4 Convnextv2 model. Tags were edited for accuracy and improved outfit consistency. Tags for facial expressions, camera angle, and image composition were added.
  • Used network_dimension 128 (same as usual) / network alpha 128 (default)
  • Trained without VAE.
  • Training dataset available here.

Revisions

  • v3 (2023-02-06)
    • Completely re-trained to correct issue where caption files were not being loaded correctly. New version should have more flexibility but requires additional outfit prompting.
  • v2b (2023-01-28)
