Koto 22B (Pretrained)

Koto-22B-PT is a depth-upscaled version of Mistral-Nemo-Base-2407, healed and trained on almost a billion tokens of creative writing data.

Usage

This model is not intended for use outside of raw text completion settings, such as cowriting. Instruct will not work. Multi-turn roleplay will not work.

It was trained at 32k, but as not all samples were this long, we expect that in the best case you can get ~16k effective context.

We found that 1.5-1.55 temperature and 0.05-0.1 min_p worked best, but YMMV!

Datasets

Some of the data used to train this model includes:

Most of The Anarchist Library, a repository for anarchist manifestos and writing (see allura-org/the-anarchist-library)
A random sample of public domain books from Project Gutenberg
Furry (anthro and feral) storytelling and smut
A small subset of known high-quality books and story data

Training Notes

This model was trained over the course of ~14 hours on an 8xB200 node. We used 8-bit AdamW and the REX LR scheduler, as well as both gradient clipping and weight decay for regularization.

There was a very odd loss spike ~60% of the way through training, but it recovered and the model seems fine? So? Eh? If it works it works :3

Finetuning Notes

This model has had ChatML tokens already added if you prefer to tune using that chat format. Please do not readd them to maintain the vocab size for (possible) usage on places like Featherless
