ChatGPT Plus: 1x usage, $20
Pro 100: 5x usage, $100
Pro 200: 10x usage, $200 (previously was 20x usage, $200)
Pro 500: 25x usage, $500
So, essentially scaling is equal. You get the same amount of usage from 25 ChatGPT Pro accounts as you do from one Pro 500 account.
It's fair, but a big of a rug pull considering how good of a deal Pro 200 was.
I think the bottom one is called "Plus", right? I get that confused too.
