These are always amazing when juxtaposed with apparently impressive LLM reasoning, knowledge, and creativity. You can trivially get them to make the most basic mistakes about words and numbers, and double down on those mistakes, repeatedly explaining that they're totally correct.

Have any systems tried prompting LLMs with a warning like "You don't intuitively or automatically know many facts about words, spelling, or the structure or context of text, when considered as text; for example, you don't intuitively or automatically know how words or other texts are spelled, how many letters they contain, or what the result of applying some code, mechanical transformation, or substitution to a word or text is. Your natural guesses about these subjects are likely to be wrong as a result of how your training doesn't necessarily let you infer correct answers about them. If the content or structure of a word or text, or the result of using a transformation, code, or the like on a text, is a subject of conversation, or you are going to make a claim about it, always use a tool to confirm your intuitions."?

This is a great idea. Like, if someone asked me to count the number of B's in your paragraph, I'd yeet it through `grep -o 'B' file.txt | wc -l` or similar, why would I sit there counting it by hand?

As a human, if you give me a number on screen like 100000000, I can't be totally sure if that's 100 Million or 1 Billion without getting close and counting carefully. Should ought have my glasses. Mouse pointer helps some as an ersatz thousands-separator, but still.

Since we're giving them tools, especially for math, it makes way more sense to start giving them access to some of the finest tools ever. Make an MCP into Mathematica or Matlab and let the LLM write some math and have classical solvers actually deal with the results. Let the LLM write little bits of bash or python as its primary approach for dealing with these kinds of analytical questions.

It's like giving a kid a calculator...

With data starvation driving ai companies towards synthetic data I’m surprised that an easily synthesized problem like this hasn’t been trained out of relevance. Yet here we are with proof that it hasn’t

I love this test. Demonstrates the "understanding" process of the language model.
