Has anyone been able to separate creativity from hallucination in LLMs? As in: we can affect one without the other, or measure one without the other. In humans we understand when someone is doing one vs. the other. The biggest difference is that a creative person knows they will have to take action to bring about their vision, but a hallucinating person thinks their vision already exists.

It seems like the LLM phenomenon that we call hallucination is descriptively the same phenomenon that we call creativity in other contexts. If the LLM adds a new function or feature to the current project as part of work on another feature, that's creativity. But if it assumes a function or type in another project, which can't easily be changed, we call that hallucination. Even though it could just as easily add that feature if it had access to that code as well.
