Description

About this course.

Watching two AI characters actually talk to each other, in real time, in a 3D world you built yourself, is a different kind of project.

This course walks you through building that in Godot 4.8, powered by local models through Ollama.

► Connect Godot to Ollama and build 3D characters with live dialogue.

► Prompt-engineer distinct personalities with persistent conversation memory.

► Add local text-to-speech using Kokoro through a FastAPI server.

► Build a multiplayer server for shared topic control and viewer input.

By the end, you'll have a full local AI conversation app, server, TTS, and clients, all running together.

✅ Lifetime access to all modules.
