GPT Discord Bot

Example Discord bot written in Python that uses the chat completions API to have conversations with the gpt-3.5-turbo model, and the moderations API to filter the messages.

This uses the same model that powers ChatGPT, but it does not necessarily have the same configurations as ChatGPT, so it won't necessarily give the same kind of responses like you would expect from ChatGPT.

This bot uses the OpenAI Python Library and discord.py.

Features

• /chat starts a public thread, with a message argument which is the first user message passed to the bot
• The model will generate a reply for every user message in any threads started with /chat
• The entire thread will be passed to the model for each request, so the model will remember previous messages in the thread
• when the context limit is reached, or a max message count is reached in the thread, bot will close the thread
• you can customize the bot instructions by modifying config.yaml
• you can change the model to other chat models (e.g. GPT-4 models), the hardcoded value is gpt-3.5-turbo

Comparision of this model with text-davinci-003

• It is more cheaper than the text-davinci-003
• Unlike text-davinci-003, it cannot differentiate between users, if more than 1 users are talking to it in the same thread, it sees them all as the same user
• It is generally more capable and optimised for chat than text-davinci-003

Setup

1. Copy .env.example to .env and start filling in the values as detailed below
2. Go to https://platform.openai.com/account/api-keys, create a new API key, and fill in OPENAI_API_KEY
3. Create your own Discord application at https://discord.com/developers/applications
4. Go to the Bot tab and click "Add Bot"
   • Click "Reset Token" and fill in DISCORD_BOT_TOKEN
   • Disable "Public Bot" unless you want your bot to be visible to everyone
   • Enable "Message Content Intent" under "Privileged Gateway Intents"
5. Go to the OAuth2 tab, copy your "Client ID", and fill in DISCORD_CLIENT_ID
6. Copy the ID the server you want to allow your bot to be used in by right clicking the server icon and clicking "Copy ID". Fill in ALLOWED_SERVER_IDS. If you want to allow multiple servers, separate the IDs by "," like server_id_1,server_id_2
7. Install dependencies and run the bot

   pip install -r requirements.txt
   python -m src.main
   

   You should see an invite URL in the console. Copy and paste it into your browser to add the bot to your server. Note: make sure you are using Python 3.9+ (check with python --version)

Optional configuration

1. If you want moderation messages, create and copy the channel id for each server that you want the moderation messages to send to in SERVER_TO_MODERATION_CHANNEL. This should be of the format: server_id:channel_id,server_id_2:channel_id_2
2. If you want to change the personality of the bot, go to src/config.yaml and edit the instructions
3. If you want to change the moderation settings for which messages get flagged or blocked, edit the values in src/constants.py. A lower value means less chance of it triggering.
