All LLMs hallucinate, but Heidi seems to have a particular propensity for hallucinating dates for when a procedure supposedly happened, and making up patient age. It particularly likes to pretend that MRI scans were done on today's date, which is
never
true.
I know that this kind of error is hard to contain, but such an obvious and unnecessary hallucination undermines confidence in the system. Can I suggest introducing a validator that ensures that dates and ages are only included if specifically mentioned in the transcript?
