Venture capitalist Marc Andreessen reignited the debate over artificial intelligence in healthcare after praising a new OpenAI finding suggesting physicians identified fewer flaws in GPT-5.6's medical responses than in responses written by doctors.

AI Doctor Claim Sparks Debate On Saturday, Andreessen posted on X while reposting OpenAI CEO Sam Altman's comments about the company's latest AI model.

"AI is already a better doctor than 99.99% of human doctors.

This is good news," Andreessen wrote.

His post came in response to Altman's statement highlighting the results of an evaluation of GPT-5.6.
