What is the value of this "output"? If I want to know what LLMs think about something, I can go ask an LLM any question I want. For a comment on [a site like] HN, either the substantive content of the comment originated inside a human mind, or there is no substantive content that I couldn't reproduce by feeding the comment's context into an LLM. At the extreme, I don't have any interest in reading or participating in a conversation between a bunch of LLMs.
They’re referencing LLM-enhanced output.
The value proposition is that someone who is a lousy writer (perhaps only in English) with deep domain knowledge is going back and forth with the LLM to express some insight or communicate some information that the LLM would not produce on its own.
