-## Usage
-Use any or all of these tags to summon Kokona:
-`1girl, halo, animal ears, orange eyes, long hair, grey hair`
-She really doesn't need many, just `1girl, halo` is enough to summon an instantly recognizable version of her.  The model may be a little overtrained but it looks good.
+Note: This is an older model and does not perform as well. It is somewhat difficult to change Kokona's outfit due to poor tagging and a small dataset. I will re-train the model at some point to resolve these issues.

+## Preview
 
-For her normal outfit:
-`china dress, vertical-striped dress, white skirt, frilled skirt, off-shoulder, jacket`

-Somewhat frequently, a strange, mysterious man in a black suit likes to appear out-of-frame beside her.  You can shoo him away with `1boy` in the negative prompt.  Not sure why this happens as there was nothing like it in the training data.

-The AI is generally pretty good at picturing her, but it really struggles with her pout.  Try various combinations of `pout`, `:t`, `pouting` and negative prompt `wavy mouth` to try to get it to appear correctly, or just use img2img without the LoRA.  It seems to be related to the LoRA since vanilla NAI can do pouting just fine.

-Her stamp is in the training data and it sorta knows what it is but is probably too small to be recognized by the AI.

-You can add or ignore `kokona, blue archive`; while they were in her captions, their effects aren't especially strong.

-Weights close to 1 work well with her, she's very cooperative.

 ## Training
 *All parameters are provided in the accompanying JSON files.*
 - Trained on 95 curated images, repeated 7 times (665 total images / 3 batchsize  = ~222 iterations per epoch, 3 epochs)
-  - Dataset included a mixture of SFW and NSFW.
-- 1.5e-5 learning rate, same as Iroha.
+- 1.5e-5 unet learning rate, 1.5e-4 text learning rate
 - Dataset was tagged with WD1.4 interrogator.  Shuffling was enabled.
   - `kokona, blue archive` were added to the start of each caption.  keep_tokens=2 was set to prevent shuffling those tokens.
-- No variants, she's well-behaved.

+## Revisions
+- v1 (2023-01-12)
+  - Initial release.
+  - **Note:** this is an old model from 2023-01-12 and is not as flexible as my newer models, however it still works pretty well. I'll try to re-train it soon with improved tagging and training parameters so that Kokona can be customized further.
