- Why do LLMs often fail at counting letters in a word?
The model sees tokens, not individual letters, so a word like "strawberry" may arrive as two or three chunks and the model never directly sees its spelling. It must guess letter counts from patterns, which is unreliable. Using code for counting fixes this.
