“A $200 ChatGPT Pro 20x subscription could cost as much as $14,000 in API pricing if fully utilized.”

What is being said is that in a month time you can burn through $14,000 worth of tokens. It does not show that that comsumption would cost ChatGPT the full $14,000.

So what they are doing here is planting the idea that a $200 subscription is actually worth $14,000. Which makes if very easy for them to make people switch to tokens or just increase the price of your subscription without losing too many customers.

No, but if you get that number in everyones heads, there is much less resistance to, say a 100 EUR a month increase.
