Hi Scott, did you also reach out in our chatbot last night? I answered you there but here it is as well:
Based on what I am reading, this is a functionality that ChatGPT subscription provides but they don't seem to make it available in the version they are giving us via API. So it is hallucinating as far as I can tell. But if you happen to find anything to the contrary please let us know and we can look further.
