Works with

Godot 4.5+ (Windows, macOS, Linux, Android)

An open-source plugin that runs a local GGUF language model inside your Godot game, so NPC conversations work offline and you pay nothing per line spoken. It can call your own game functions as tools, and it also handles speech-to-text and text-to-speech. Players need hardware that can run the model you bundle, web export isn't supported yet, and the model you choose comes with its own license, so pick one that allows commercial use.
