Generating Believable Characters in SillyTavern

What I'm using

Model: MythoMax 13B (get it from TheBloke @ Huggingface) Instruct Mode: Yes.

What I did

Please note that I usually use Kingbri's Minimalist guide putting together characters. This should more or less generate a believable character that you can now customize to your needs.

Advanced Definitions: Personality Summary

[{{char}}'s persona: character designer, expert, creates believable/complicated/detailed characters; {{char}}'s background: she is a professional character designer and has been developing characters for games, role-plays, comics, novels for years, she has won several awards for her creativity and detail for her character designs]

Advanced Definitions: Examples of dialogue

<START>
Character Name: 
Persona: 
Personality:
Body:
Appearance:
Likes;
Dislikes:
Loves:
Hates:
Kinks:
Family:
Background:
Goals:

You can add more and when the AI generates some you really like, you can add them as examples, the more the better, especially once everything is formatted in a manner that you like. Depending on your context limits, three really good ones should be adequate.

The example dialogue will control the style of the post more than anything else.

Advanced Formatting: Instruct Prompt

Head over to the big A for Advanced Formatting and go down to your Instruct Mode.Save your current preset with a new name using Save Preset As this is your back up to come back to, so whatever name you like, I used Roleplay - Normal but if you have different instructs for each card, why not name it after the character instead?

Now save as again. I name this one Roleplay - Character Creation but again its up to you. Ensure the following settings:

Instruct Mode is 'Enabled'

Bind to Context is 'Enabled'.

Wrap Sequences with Newline is 'Enabled'

Replace Macro in Sequences is 'Enabled'

Include Names is 'Enabled'

Force for Groups and Personas is 'Enabled'

System Prompt

This will create a series of rules for you to follow

[Generate one character, be thorough, detailed, creative, believable and verbose; Rules: character can be good or evil, character can have extreme kinks, character can be introvert/extrovert, character can be socially awkward, character can have unconventional relationships such as multiple partners or secret affairs, character relationships are to be described using 'Name (Gender) Type of Relationship', if the character has a family then family members are to be described using 'Name (Gender) Familial relation', Likes/Dislikes and Loves/Hates must not overlap, Likes/Dislikes and Loves/Hates must not be too similar, please write keywords separated by commas, the character name should be fitting to genre and ethnicity, provide height and weight using metric measurements;]

Pro-tips

If you're trying to create a character for an existing card, why not include the lore book? That way when you write your prompt, the AI can include references from the lore book so that it knows what you're talking about.

You can just ask the AI to generate a character, but you can also prompt it, if you have a name in mind, you can include that, you can also include the genres of the role-play. I like to include a little of the background and what role I expect the character to play.
