So, when the page now says "$6.51/hr // $4,752/mo", that's really just presenting the same actual cost you'd have to pay, across two different time metrics? As in, you pay $6.51/hr, or you pay $4,752/mo, same thing, but not both?
I think you need to consider: Your competitors (e.g. AWS) generally structure annual commitments as an upfront (or monthly) payment + a reduced cost per hour/minute for the resource being reserved; that's the lens through which most people viewing this page will be thinking. If that is not how you structure annual commitments, then that should be made very clear.
If my first paragraph is correct (and again, the page is still confusing, its not obvious to me that this interpretation is correct): You should list one price, and give a dropdown at the top to change the computation of that price across whatever timeframe the user wants ($/hr, $/day, $/month, etc). That would also free up some space in-line to put a chip that says something like "-15% discount!".
