There's "Ask ChatGPT" overlay at the bottom of the page, so I asked "how risky is giving my medical data to OpenAI?" Interestingly ChatGPT advised caution ;) In short it said: 1. Safer than standard AI chats, 2. Not as safe as regulated healthcare systems (it reminded that OpenAI is not regulated and does not follow e.g. HIPAA), 3. Still involves inherent cloud risks.
