How to Gather Character Data

Option 1: Pre-Made Datasets (Kaggle)

Popular options:

• Harry Potter scripts
• Rick and Morty dialogues
• Game of Thrones transcripts

Option 2: Custom Transcripts

1. Find raw text on Transcript Wiki.

Training Your GPT Model

• Base Model: DialoGPT-small (adjust size as needed).
• Training Time: ~10 minutes for 700 lines.
• Pro Tip: Incrementally increase epochs while monitoring output originality.

Hosting on Hugging Face

1. Tag models as conversational in the README.
2. Verify live chat functionality via Hugging Face’s UI.

Building the Discord Bot

Python Example:

import discord
from transformers import pipeline
bot = pipeline('text-generation', model='your-huggingface-model')

JavaScript Alternative:
Specify Discord.js v12.5.3 in package.json for Repl.it compatibility.
