American billionaire Mark Cuban on how he will use Claude, ChatGPT and Gemini if he was a doctor

Mark Cuban has outlined a forward-thinking blueprint for modern healthcare, detailing how he would leverage leading artificial intelligence (AI) platforms, including OpenAI’s ChatGPT, Anthropic Claude, Google Gemini and Grok, if he were operating a private medical practice. The billionaire entrepreneur said that rather than treating generative AI as a replacement for clinical care, Cuban’s concept centers on turning large language models (LLMs) into collaborative assistants that keep patients and doctors continuously aligned between appointments.

Hands-on AI configuration in the exam room

Under Cuban’s proposed approach, a physician would sit down directly with a patient during a consultation to personally customise their AI assistant of choice. The doctor would embed specific instructions, capabilities and recurring routines tailored to the patient’s individual treatment plan.“If I was a doctor with a private practice, I would offer to sit with the patient and configure their Claude, ChatGPT, Gemini and Grok with instructions and skills, along with a series of prompts/tasks that the patient can use and that can be shared with the doctor and inform the patient,” Cuban said in a post on X (formerly Twitter).

Automating daily health monitoring

To demonstrate how the system functions in practice, Cuban outlined a basic automated prompt structure like instructing the model to prompt the patient with targeted health questions every evening at 5:00 pm, generate relevant feedback and automatically email a full record of the exchange directly to the doctor once finished.“LLM , every day at 5pm I want you to ask Joe the following questions , and show him your response. Upon completion , I want you to email me everything in this chat. Every morning I want you to look for new questions I emailed joe that will come from my email with the subject Questions. Rinse and repeat. You get the point,” he added.The primary goal of the strategy is straightforward: guide patients on how to use AI effectively so the technology can assist healthcare providers in delivering better care.
