I'm already on Pro. Why should I keep it?
Only reason to keep it is if you like their UX and auto-complete. Everything else is on pay per use and if you don't use all of it (good luck with the 5 hour and week caps) you have just paid more for the auto-complete
The deal is really pretty much garbage now and I believe that is the intent.
e.g. if on an annual plan? 0x will be gone, but there are okay 1x and 0.3x models left. I am pretty much curious how the early may test invoicing will look like. current setup of tools etc. is way too chatty eats up 1+M token per PRU easily. not sure how much is cached.
