I think this used to mean can it be run offline and right now (usually) whenever there is an LLM involved the answer is soundly no
Ah! Right now our default is set to use OpenAI... but you can actually use local LLMs by creating a custom agent. We're going to add a full stack of local STT/TTS/LLM... just haven't had time for it yet!
If anyone wants to help with it we're totally open for contributions :)
