OpenAI’s latest language model, GPT-5, is showing powerful new potential in an area that truly matters and that is our health. While ChatGPT has already been used by many for everyday medical advice, GPT-5 goes a step further, it can now flag serious health concerns, including cancer, based on what you type into the chat.
At a demo during its launch event which was streamed live, OpenAI highlighted health as one of GPT-5’s most meaningful and improved capabilities. According to the team, GPT-5 scored higher than any previous model on OpenAI’s internal health evaluations, a benchmark, which was developed with input from over 250 physicians, testing the model on real-world health tasks.
One story stood out in the presentation and it came directly from someone who had lived through a medical crisis.
Carolina, a user who was diagnosed with three types of cancer in the same week, shared how she turned to ChatGPT in a moment of panic. Upon receiving a biopsy report filled with complex medical language, she pasted it into ChatGPT for help. Within seconds, the model translated the medical jargon into plain English. It didn’t just ease her anxiety, it gave her clarity at a moment when she felt completely lost.
“That moment was really important,” she said. “Because by the time I spoke with my doctor three hours later, I already had a baseline understanding of what I was dealing with.”
Throughout her treatment journey, she continued using ChatGPT to break down difficult options, weigh risks, and even prepare questions for her doctors. In one particularly difficult decision, whether or not to undergo radiation when the doctors themselves were divided, GPT-5 helped her understand the pros and cons in a deeper, more personalized way.
What makes GPT-5 special, according to OpenAI, is not just that it explains information well. It can understand context and connect the dots, acting less like a search engine, and more like a thoughtful partner. It can interpret what's not in the report, suggest what’s missing, and offer next steps, something Carolina and her husband said felt incredibly empowering.
“It helped me become an active participant in my care,” she said.
While GPT-5 is not a medical device or a replacement for doctors, it is proving to be a powerful new tool for health literacy and support.
