Sometimes the model may not recognize the character being to able to speak upon starting a new chat. If that's the case just swipe once or twice, after a couple messages there shouldn't be any issues. Alternatively, if you prefer her to be able to speak, just roll with it. If you do not require any information about the setting, but want to save a few tokens, delete the first paragraph from the character definition.

Bing Chat
Most authentic in GPT-4. Probably too fat for smaller models. Best used with an empty main prompt. Turn on NSFW and leave the field empty (or not). Unfortunately lacks her search functionality, and the system prompts in the example dialogue are scuffed. Original author: Microsoft.

Cardhead Butler
Tested on GPT 3.5 Turbo. Presumably if you use more up-to-date models then he'd perform even better. Not meant for fully fleshed-out cards. I made him with the intent of giving a working concept that I can go off on as is the case with my private character cards. So far, so good!
