ollamachat
by xingwangzhe
With ollamachat installed, players can talk to a language model that runs on their own computer through the Ollama service, using in-game commands.
What it does
The mod lets players chat with a model deployed locally through Ollama, from inside Minecraft. Ollama must be on the computer with at least one model available, for example llama3 added with the ollama pull command, and the local service must be started with ollama serve before chat works. Replies arrive as dynamic, AI-generated conversation in the game.
ollamachat is a Fabric mod for Minecraft 1.20.1 and runs on the client only, so a server does not need it and players join without installing anything. The code is open source under the MIT License, and its files are published for 1.20.1, with 1.0.1-1.20.1 as the latest build from 2025-02-04. Source code and an issue tracker are publicly available.
Key features
Real-time chat
Messages sent in game are passed to the local model and the answers appear in the chat window as they come back.
Model switching
A command selects which locally deployed model answers, so different models can be tried without restarting the game.
Set model command
The chosen model is stored with a set model command, letting players keep a preferred model for later sessions.
Service control
In-game commands check and manage the connection to the local Ollama service, so the game can recover if it is stopped.

Use cases
Roleplay and quests
Players can give a chat character a role in an adventure or a storyline and let the model respond in that voice.
Experiments with local models
Anyone who wants to compare models pulled into Ollama can switch between them from the game and see the answers side by side.
Who it’s for: The mod suits players who already run Ollama on their own machine and want a language model available in singleplayer chat. It is a client-side tool, so it fits personal play rather than server administration.
