I had similar thoughts. The readme intro explicitly mentions hallucinations, that's why I thought I'd ask.

If you're dealing with uid in -> uid out, where you're hoping to get the same uid out, intuitively the entropy would be greatly reduced anyways. Then the question becomes, are words conducive to keeping input->output consistent, given the way LLMs work (e.g. attention mechanism)? I could see it go either way, that's why I'm supporting the idea of running your experiment.
