And yet what you are saying just isn't true in my experience.

I use speech to text with Claude Code and other LLMs and often have terrible grammar and lots of typos and stuff and it never affects the output. But if I go by what you are saying then it would only seem right that the code it outputs is more sloppy? Also the length of a response entirely depends on what I'm using for example ChatGPT always gives me a long response no matter what I ask it and the Claude app always gives short responses unless I specifically ask for something longer. This is because of how they are given instructions and is not inherent to LLMs.
