I estimate that if you use AI correctly, you can augment your effective applied intelligence by about 1.5 SD. That’s about 24 IQ points. I ran some of my recent projects, augmented and non-augmented, past 5 AI models, and they all produced results in much the same range. You can read the results of one of them at AI Central.
Obviously, your mileage will vary. And note that this has nothing to do with the quantity of the output, only the caliber of it.
However, if you’re going to use AI as a mirror, or to pat you on the head and tell you how brilliant you are, there is nothing there to augment, you are wasting your time, and you might as well just watch television.
