Ollama Persona Discord bot

This project allows you to run your custom Ollama persona locally as a Discord bot. It can:

• Mimick a virtual character (see Mavin, Kirby or Pastafari)
• Provide mental and relationship help (see Samantha), This doesn't replace professional help
• Python code teacher
• Dungeon Master assitant to generate encounters on the flight

Quickstart

# Use WSL on Windows, skip on Linux/MacOS
wsl --install Ubuntu-24.04
wsl

# Install Ollama and pre-pull mistral
curl -fsSL https://ollama.com/install.sh | sh
ollama pull mistral

# Start your bot
git clone https://github.com/AlexisTM/ollama-discord-persona-rs
cd ollama-discord-persona-rs
DISCORD_BOT_TOKEN=DISCORD_BOT_TOKEN ./run.sh marvin

# or manually
ollama create marvin -f modelfiles/marvin.modelfile
DISCORD_BOT_TOKEN=DISCORD_BOT_TOKEN cargo run --release modelfiles/marvin.json

Commands

• Direct message: The persona replies to the message
• /botname prompt: Slash command to contact a specific persona
• /clear: Slash command to remove the persona memory

Custom bot

To make your custom persona, create a modelfile like marvin.modelfile (see the Modelfile format) and prepare your network. To get your modelfile started, use ollama show [modelname] --modelfile

Then, create a json file with the botname, the model you just created and optional extra generation options to overwrite the PARAMETER you set in the modelfile (Options available)

{
    "botname": "Marvin",
    "model": "marvin",
    "options": {
        "temperature": 0.5,
    }
}

You can then run the persona as:

ollama create marvin -f modelfiles/marvin.modelfile
DISCORD_BOT_TOKEN=DISCORD_BOT_TOKEN cargo run --release modelfiles/marvin.json

The botname should not have special characters nor spaces right now, to be compatible for the /slash command.

Technical help on how to make a Discord bot:

Create a bot application: https://discordpy.readthedocs.io/en/stable/discord.html

Configure intents for your bot: https://discordpy.readthedocs.io/en/stable/intents.html

In the oauth section of discord dev portal, make a link to allow your bot to join your server such as:

https://discord.com/api/oauth2/authorize?client_id=APPID&permissions=2215115840&scope=bot

In this case, we only need the bot scope and READ/WRITE messages permissions
