I don’t know what AGI really means at this point, and I don’t think this is quite there, but this is an example of ChatGPT (4o) choosing the correct context (counting only alphabet characters not total character count), parsing the comment correctly (non-trivial given the usage of delimiters in both the prompt and comment and reference to counting letters in the comment not being interpreted as a part of the instructions), choosing the correct python tools, arriving at the correct answer, then generating and populating a working, downloadable, notebook to check the work. All in one reply.

It looks like you would need to continue the conversation from the link I provided then regenerate the prompt/reply to see the processing blocks and download the notebook.
