I admit I don't see how that will happen. What are they gonna do? Maintain a model (LoRA, maybe) for every single advertiser?
When both Pepsi and Coke pay you to advertise, you advertise both. The minute one reduces ad-spend, you need to advertise that less.
This sort of thing is computationally fast currently - ad-space is auctioned off in milliseconds. How will they do introduce ads into the content returned by an LLM while satisfying the ad-spend of the advertiser?
How does X then change "on the fly" if ad deals are changing? Constantly re-training with whatever advertiser is the current highest paying on?
In google ad times, this was realtime bidding in the background - for AI ads this does not work, if Im right?
