With the launch of GPT-5, OpenAI has begun explicitly telling people to use its models for health advice. At the launch event, Altman welcomed on stage Felipe Millon, an OpenAI employee, and his wife, Carolina Millon, who had recently been diagnosed with multiple forms of cancer. The trio called it an empowering example of shrinking the knowledge gap between doctors and patients. Indeed, two days before the launch of GPT-5, the Annals of Internal Medicine published a paper about a man who stopped eating salt and began ingesting dangerous amounts of bromide following a conversation with ChatGPT. As things stand, there’s little indication tech companies will be made liable for the harm caused.
