Which AI model does my agent use, and should I change it?

By default a new agent uses a very fast AI model, chosen because it is bright and has low latency. You can set your own model in the agent, but unless you know what the setting does, leave it as is, because the default already has good settings.

Newer and smarter models cost more and are slower. You do not need the most advanced model to run a receptionist or book appointments, and on the phone speed matters: callers cannot wait six to ten seconds for a reply.
