Yes, that is why I say 'if they had'. No way they have that many now but amoungst my associates many are still just starting to purchase the payed subscriptions.
One advantage that I hope a paid version of GPT4 has (like ChatGPT Premium) over a free one (like Bing), is that it is a matter of time before the Bing answers will be polluted by whatever an advertiser is willing to spend its money on. Whereas with ChatGPT I am the paying customer.
I say "I hope", because time and time again it was shown that companies happily take money from both sides and skew the product to the wishes of the one that pays most, i.e. not me.
And since the results of AI are way less transparent than the appearance of an ad, the user will be screwed. If anything, GTP is a master of undetected product placement.
So in the end it will all be in vain, but for now, the paid version looks better than the free.
Not for many specific topics. If Nike pays OpenAI millions of dollars to overweight their products in the model, do you think they are going to say no? Maybe for now during the hyper growth phase, but long term I expect there will be hundreds of companies with large ad budgets paying the leading AI companies to skew output or censor certain results in their favor.
