About this Mod

Ollama MC

Have you ever wanted to chat with an LLM with your (very real) friends (that you totally have) in minecraft?

Well you can today!

Setup and Requirements

  • Install ollama and install an LLM, by default the LLM in config is llama3.1:latest.
  • Have the web server running, by default at http://localhost:11434/
  • Run your client with the mod

Features

  • /ollamaresetconvo resets the chat, also needed after changing config file in-game
  • Setting a name for your LLM, saying this in chat will trigger it to respond (it might take a bit depending on your PC, if it doesn't show up check your logs)
  • Other players can talk via the same name you talk to it with

Known Issues

  • In servers with no chat reports, messages are very wonky, so messages have to follow the format (username): (message) or <(username)> (message)
  • Some messages from the server such as plugins, /tellraw command, etc that follow the same format as chat messages can cause a network protocol error and I'm too lazy to fix it.
