If you don't see the AI system that you are using, no worries, just select one with the approximate token (character) limit.
The maximum specified is to allow the AI system (e.g. ChatGPT) to have available context to chat with you and answer your questions.
unlimited is used to override the practical limits on chat package sizing. There is no "unlimited" AI system.
