From what I understand, in the new plan the 1,500 AI requests don't roll over. Only the add-on credits you buy on top of that will roll over and expire after 12 months.
Here’s where I got it from, but I see how it’s ambiguous. “You pay for what you use” sounds a bit like the BYOK (bring your own key) “add-on credits” pricing model you’re referring to.
But in the pricing table, they refer to monthly “AI credits”.
