# E621 Rising V2: A Stable Diffusion 2.1 Model [epoch 29]

* Guaranteed **NSFW** or your money back
* Fine-tuned from [Stable Diffusion v2-1-base](https://huggingface.co/stabilityai/stable-diffusion-2-1-base)
* Training continued from [E621 Rising V1](https://huggingface.co/hearmeneigh/sd21-e621-rising-v1)
* 10 additional epochs of 250,000 images each, collected from [E621](https://e621.net/)
* Trained with [6,246 tags](https://huggingface.co/hearmeneigh/sd21-e621-rising-v2/blob/main/meta/tag-counts-by-name.json)
* `512x512px`
* Compatible with 🤗 `diffusers`
* Compatible with `stable-diffusion-webui`
* Compatible with anything that accepts [`.ckpt`](https://huggingface.co/hearmeneigh/sd21-e621-rising-v2/resolve/main/sd21-e621-rising-v2-epoch-29.fp16.ckpt) and [`.yaml`](https://huggingface.co/hearmeneigh/sd21-e621-rising-v2/resolve/main/sd21-e621-rising-v2-epoch-29.fp16.yaml) files

## Changes From E621
See a [complete list of tags here](https://huggingface.co/hearmeneigh/sd21-e621-rising-v2/blob/main/meta/tag-counts-by-name.json).

* Symbols have been prefixed with `symbol:`, e.g. `symbol:<3`
* All categories except `general` have been prefixed with the category name, e.g. `copyright:somename`. The categories are:
  * `artist`
  * `copyright`
  * `character`
  * `species`
  * `invalid`
  * `meta`
  * `lore`
* Tag names are all lowercase and only contain `a-z`, `0-9`, `/`, and `_` letters
* `:` is used to separate the category name from the tag

### Additional Tags
* Image rating
    * `rating:explicit`
    * `rating:questionable`
    * `rating:safe`

## Training Procedure

[Training legend](https://huggingface.co/hearmeneigh/sd21-e621-rising-v2/blob/main/examples/training-legend.jpg)

* 204-272 images per batch (epoch variant)
* `512x512px` image size
* Adam optimizer
  * Beta1 = `0.9`
  * Beta2 = `0.999`
  * Weight decay = `1e-2`
  * Epsilon = `1e-08`
* Constant learning rate `4e-6`
* `bf16` mixed precision
* 8 epochs of [V1 dataset](https://huggingface.co/datasets/hearmeneigh/e621-rising-v1-curated) samples stretched to `512x512px` (ignore aspect ratio)
* 9 epochs of V1 dataset samples resized to `512xH` or `Wx512px` with center crop (maintain aspect ratio)
* 2 epochs of V1 dataset samples resized to `< 512x512px` (maintain aspect ratio)
* 10 epochs of [V2 dataset](https://huggingface.co/datasets/hearmeneigh/e621-rising-v2-curated) samples resized to `< 512x512px` (maintain aspect ratio)
* Tags for each sample are shuffled for each epoch, starting from epoch 16
