For the completion to work, the source text needs to be ‘good’. That’s a basic kernel of how the thing works. Even with a perfect oracle autocomplete if the source text is ‘bullshit’, the output is too.

Or, slightly changing this. The source text needs to speak the correct vocabulary and language to produce a good completion. See the chat where Terry Tao is doing maths with an LLM. There’s _no way in hell_ I could get to his output because I just have no idea, and can’t speak the language.

Same with any field.
