I really struggle to see a path where $.01 ad inventory covers the cost of inference, much less training or any other of OpenAI ventures. Unless every query makes you watch a 30 second unskippable video or something equally awful.
Users will ask ChatGPT for recommendations and the answer will feature products and services that have paid to be there, probably with some sort of attribution mechanism so OpenAI can get paid extra if the user ends up completing the purchase.
