Stone Rings are normally about the size of a dwarf planet, but their rings are broken into segments that can extend to allow supermassive ships to pass through. Essentially, they can be any size.

I haven't thought of the idea of an AI being built into it. There are the Ring Wardens that guard it which can serve the role of an AI, but there's nothing saying that the rings do not have an AI built into them. I would imagine that these wouldn't be superadvanced AI's though, only strong enough to regulate the Ring Wardens.
