How do you insert ADs in ChatGPT style service?

Unless they are trained to give you ads first, in its current form, it is going to be super difficult to make money out of it.

It is the Reels scenario for Facebook once again. They can copy TikTok, but they more the do, the more revenue they shift from their money maker, thus losing money.

Google will have to take it slow, making ChatGPT style component in their service, while not hurting their main resource of revenue.
