What are the limits of ROBLOX game server usage?

I have an old demo where it uses the server to train a small AI, only about 10 nodes. However, obviously, it is against ROBLOX’s Terms of Use to do something like mine bitcoin, (example) so where can I find out what exactly ROBLOX allows to be processed on the server?

I do not intend to abuse ROBLOX servers, but I feel like this is an important topic that should be clarified upon, especially when having games that may include something like training a neural network to beat the player.
