From what I understand, that's a problem with the way it receives data. The model doesn't see the letters g,o,o,g,l,e to count it. Just like how I can't sense radio waves. If I wanted to find that out, I'd get a tool to detect waves. If the LLM wants to find that out, it can write a script to find it.
Wow, which Claude model flubbed that question? Certainly not anything recent...? The 2-bit quant of K2.6 running locally on my own hardware has no problem with it: https://i.imgur.com/tL0FLjZ.png
