You can move from FULL Mode to LITE mode later. The avatars, secrets and session endpoints are the same in both modes.
FAQ
LITE or FULL Mode?
Which session mode to start with, depending on whether you already have a voice agent or LLM
Start with LITE mode if you already have a voice agent or an AI stack and want to keep running it. Start with FULL Mode if you want LiveAvatar’s managed agent to run the conversation, whether or not you have an agent today.
