Maybe it is fine in beta, but in post-beta they should not use AI for every search query. The key is going to be figuring out when the AI is adding value, especially since even running the AI for a query is 10x more expensive than a normal search. It may be hard to figure out where to apply AI though. If a user asks "whats the weather?", no need for AI. If a user asks "I am going to wear a sweater and some pants, is that appropriate for today's weather?", now you might need AI.
