Pantheon-RP-1.8-24b-Small-3.1

Note: This model does not include vision. It is text-only.

Welcome to the next iteration of my Pantheon model series, in which I strive to introduce a whole collection of diverse personas that can be summoned with a simple activation phrase.

Pantheon's purpose is two-fold, as these personalities similarly enhance the general roleplay experience, helping to encompass personality traits, accents and mannerisms that language models might otherwise find difficult to convey well.

GGUF quants are available from Bartowski, and EXL2 quants can be found here.

Your user feedback is critical to me so don't hesitate to tell me whether my model is either 1. terrible, 2. awesome or 3. somewhere in-between.

Model details

I decided to pick the Small 3.1 Instruct version despite there being a base version available - After cooking professionally for the past six months I've come to realize you're generally better off with an extensive base to better handle all the varied inputs an user could possibly throw at this, a benefit that usually outweighs the drawbacks.

This time the recipe focused on combining as many data sources as I possibly could, featuring synthetic data from Sonnet 3.5 + 3.7, ChatGPT 4o and Deepseek. These then went through an extensive rewriting pipeline to eliminate common AI cliches, with the hopeful intent of providing you a fresh experience.

Inference

Mistral really loves recommending unusual inference settings but I've been getting decent results with the settings below:

"temperature": 0.8,
"repetition_penalty": 1.05,
"min_p": 0.05

Having character names in front of messages is no longer a requirement but remains a personal recommendation of mine - It seems to help the model focus more on the character(s) in question.

Prompt Format

The model was trained using ChatML.

General Roleplay

The model has been trained on three distinct categories of roleplay - Pantheon personas, general character cards and text adventure, the latter borrowing some from AI Dungeon's Wayfarer project.

Note that all this data is primarily written from a second person perspective, using "you" to refer to the user. This is based on my personal preference. Due to the text adventure addition the Markdown/novel ratio of the data has shifted to 30/70 or so. It should work well with both styles.

Lyra the Assistant

Lyra has shifted from assistant to Pantheon persona, taking Aiva's place. In practice I much prefer to rely on models like Sonnet 3.7 if I'm doing anything remotely serious. This means Pantheon is now fully focused on immersive roleplay.

Pantheon Personas

Half of the Pantheon's data was regenerated using Sonnet 3.7 and then rewritten to counter the majority of cliches. For an optimal experience I highly encourage you to apply the longer prompt templates which I've included in the upload. Make sure to describe yourself as well!

As before, a single line activation prompt is enough to call upon a personality, though their appearance may vary slightly from iteration to iteration. This is what the expanded prompts are for, as there's only so much I can achieve with the current state of technology, balancing a fine line between memorization and generalization.

To give the persona something to work with I suggest you also add the following two lines to it;

Regarding the user: (Name, appearance, etc)

Location: (Where are you two? What are you doing?)

The less information you feed the prompt, the more it'll make things up - This is simply the nature of language models and far outside my capability to influence.

Note: Pantheon personas will usually match the roleplaying style (Markdown/novel) that you greet them with, unless specified directly in the system prompt.
