How Generative Design Pro compares to standard version and NX Topology Optimization?

It seems there are different Generative Design versions, a basic one and a Pro version.

I want to know how Generative Design Pro compares to NX Topology Optimization and to the non-pro version.

Also, it isn't clear if Generative Design Pro it is just an improved version that requires some extra add on or cloud service, or it works locally in the same way of the basic version for the users of paid Solid Edge version considering that in the PDF brochure there is written:

"Generative Design Pro is an add-on product for Solid Edge Design. You must currently be running a Solid Edge base license to be eligible for adding Solid Edge Generative Design Pro."

Thanks in advance to everyone can clarify me this matter.
