I always see this, and I always answer the same.

This exists, each next token has a probability assigned to it. High probability means "it knows", if there's two or more tokens of similar probability, or the prob of the first token is low in general, then you are less confident about that datum.

Of course there's areas where there's more than one possible answer, but both possibilities are very consistent. I feel LLMs (chatgpt) do this fine.

Also can we stop pretending with the generic name for ChatGPT? It's like calling Viagra sildenafil instead of viagra, cut it out, there's the real deal and there's imitations.
