PAINTED FANTASY

Mistral Small 3.2 24B

Overview

Experimental release.

This is an uncensored creative model intended to excel at character driven RP / ERP.

This model is designed to provide longer, narrative heavy responses where characters are portrayed accurately and proactively.

Training Process

Training process: Pretrain > SFT > DPO > DPO 2

Did a small pretrain on some light novels and Frieren wiki data as a test. Hasn't seemed to hurt the model and model has shown some small improvements in the lore of series that were included.

The model then went through the standard SFT using a dataset of approx 3.6 million tokens, 700 RP conversations, 1000 creative writing / instruct samples and about 100 summaries. The bulk of this data has been made public.

Finally DPO was used to make the model a little more consistent. The first stage of DPO focused on instruction following and the second tried to burn out some Mistral-isms.

> Axolotl configs

Not optimized for cost / performance efficiency, YMMV.
