I think that only applies to held-over users on the annual plan:
> Users on annual Pro or Pro+ plans will remain on their existing plan with premium request-based pricing until their plan expires, however, model multipliers will increase on June 1 (see table).
Kind of. Monthly users moving to an entire different pricing model so we don't really know what the increase in price will be for them.
Thanks this is helpful. I am on my first month of annual Pro. Should I keep it or cancel it (ask for a refund)?
There will surely be corresponding, different AI credit costs for each model.
