| Be forewarned that this LoRA is prone to generating NSFW results since Sora has an unusually high proportion of extremely lewd art. Use `nsfw, naked apron` etc in the negative prompt to prevent this. | |

| ## Usage | |
| Use any or all of the following tags to summon Sora: `sora, halo, mini wings, white wings, two side up, blonde hair, forehead` | |
| For her usual outfit: `blue apron, white shirt, (black pleated skirt:0.8)` | |
| - If needed, you can also add `off-shoulder, strap slip, bowtie, short sleeves` | |
| - Sora's skirt is not visible in most training art. Consider adding `black pleated skirt` and negative prompt `miniskirt, pencil skirt` for more accuracy. | |
| Sometimes her wings appear too high; `low wings` can help with this. | |
| Weight 1 is suggested. | |
| ## Training | |
| *Exact parameters are provided in the accompanying JSON files.* | |
| - Trained on a set of 128 images | |
| - 9 repeats | |
| - 3 batch size, 4 epochs | |
| - `(128*9) / 3 * 4` = 1536 steps | |
| - 0.0791 loss | |
| - 768x768 training resolution | |
| - `constant_with_warmup` scheduler instead of `cosine` | |
| - Initially tagged with WD1.4 Convnextv2 model. Tags minimally pruned/edited. | |
| - Used network_dimension 128 (same as usual) / network alpha 128 (default) | |
| - Trained without VAE. | |

| ## 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 (2023-02-01) | |
| - Initial release. | |
| - **Issue:** caption files were completely ignored during training. As a result, prompting "sora" grants a very strong effect, but the LoRA is highly overfit. | |
