It is smart enough that I use for all my coding tasks, and a lot of other mundane tasks.
It is probably not smart enough for "design this whole architecture of this complex system from scratch, make no mistakes", but that is not something I want from a coding tool anyway. I want a model that I can point to a file and tell it to make some changes to the file and related files. Or that I can ask to review a PR with regards to certain aspects.
My suggestion is to simply try it and see what it feels like.
