OpenAI's entire business is trivially profitable when you attach an ad network to ChatGPT.

Quick, someone point out the one billion user system with intent + personal data rich that doesn't result in a $100+ billion high margin ad network.

It is that simple and absolutely nothing can stop the gigantic ad networks that will be built up around personal agents.

Only if CPM can be high enough to counter balance the inference costs.

Current CPM is between $30 and $60 which is x20 to x30 more expensive than alternatives.

Now we have to wait and see if performance is also at least 30x of previous ad targeting.

The thing that stops it is, ironically, personal agents. Get one to interact with the ad-driven one if you need to and filter ads out.
