ollamarama-matrix

Ollamarama is an AI chatbot for the Matrix chat protocol using Ollama. It can roleplay as almost anything you can think of. You can set any default personality you would like. It can be changed at any time, and each user has their own separate chat history with their chosen personality setting. Users can interact with each others chat histories for collaboration if they would like, but otherwise, conversations are separated, per channel, per user.

This is based on my earlier project, infinigpt-matrix, which uses OpenAI and costs money to use. (Now updated with OpenAI/Ollama model switching)

IRC version available at ollamarama-irc

Terminal-based version at ollamarama

Setup

Install and familiarize yourself with Ollama, make sure you can run local LLMs, etc.

You can install and update it with this command:

curl https://ollama.ai/install.sh | sh

Once it's all set up, you'll need to download the models you want to use. You can play with the available ones and see what works best for you. Add those to the config.json file. If you want to use the ones I've included, just run ollama pull modelname for each.

You'll also need to install matrix-nio

pip3 install matrix-nio

Set up a Matrix account for your bot. You'll need the server, username and password.

Add those to the config.json file.

python3 ollamarama.py
