The example of asking it things like counting or sequences isn't a great one because it's been solved by asking it to "translate" to code and then run the code. I took this up as a challenge a while back with a similar line of reasoning on Reddit (that it couldn't do such a thing) and ended up implementing it in my AI web shell thing.
