Likewise, a "medical AI" is going to be regulated as a Class II medical device, and trying to push it out into the market without FDA approval would be ... inadvisable. This means that we're a long way from an architecture for a LLM-based medical AI that's going to pass regulatory scrutiny, but that's a good thing.
Of course, having said that, there's nothing preventing someone from using ChatGPT to draft a pro se filing or trying to self-diagnose, but that's on them at that point. Using a general-purpose product to do something stupid that inevitably ends in a FAFO scenario is a time-honored American tradition.
Doctors sometimes use Google to get information to help them make decisions, but I assume Googling isn't regulated as a Class II medical device. These days, Google doesn't even just return search results anymore, it also shows ads and tries to answer some questions by itself. Does that mean doctors are already using unregulated 'medical AI'?
