If you're asking an LLM to compute something "off the top of its head", you're using it wrong. Ask it to write the code to perform the computation and it'll do better.

Same with asking a person to solve something in their head vs. giving them an editor and a random python interpreter, or whatever it is normal people use to solve problems.

This is what I imagine the LLM usage of people who tell me AI isn't helpful.

It's like telling me airplanes aren't useful because you can't use them in McDonald's drive-through.

I find it hilarious that it rick rolled you. I wonder if that is an easter egg of some sort?

Almost any modern LLM can do this, even GPT-OSS

You should probably tell AI to write you programs to do tasks that programs are better at than minds.

Don't use LLMs for a task a human can't do, they won't do it well.

it. Not him.
