I would like to ask, the cursor 20 USD subscription includes all the features of Hobby, and additionally provides
unlimited completion, 500 fast premium requests per month, unlimited slow premium requests/
Does the 40 USD subscription also only provide 500 fast premium requests per month and unlimited slow premium requests, or does it include unlimited fast requests? Can anyone tell me?
Hi, didnt really understand the title 
I will assume you meant 11 of 500 (not 5000)
There are no more new subscriptions over 20 USD as the Usage Based pricing gives you the ability to only pay as much as you need without having to purchase in 20 USD steps. The price per request stays the same after the 500 fast premium requests. The actual request/price varies by model and is listed on the Models page. (Yes many models remain at 1 request level, some are below and some more advanced tools are charged higher but i would suggest starting with the 1/request to get used to writing prompts and trying features)
Yes as you write the 20 USD subscription includes hobby plus the other details.
As listed here.
