Rose 20B is a "frankenmerge" of several other models (notably also Noromaid 13B). The goal of the model is to serve as a basis for further fine-tuning to create a new Pygmalion 20B model.
The model was well received by the Pygmalion AI Discord community and it is also AliCat's favorite model for erotic role-play (ERP).
Very strong role-playing model, using the NovelAI (Best Guess) preset in SillyTavern. Handles high context (8-16k) well without hallucinating. Handles both "dialog" narration as well as dialog narration quite well. Tends to prefer simple scenarios. Handles both long and short RP message lengths. Consistently good results, but nothing groundbreaking. TheBloke Q5_k_m GGUF version in koboldcpp.
