"OpenAI said GPT-5.6 is a major step forward for health intelligence, highlighting that Luna at lowest effort beats GPT-5.5 at highest effort while costing 25× less. Karan Singhal added that, in blinded physician comparisons over 20,000 axis ratings, physicians found fewer flaws in GPT-5.6 responses than physician-written responses across a hard task set."

Silicon Valley is obsessed with changing the world, except I often think Silicon Valley's biggest effects are mostly second-order and unintended. I suspect AI medicine will be a great example of that. Silicon Valley players dream of the chance to be multi-billion dollar revenue unicorns; meanwhile, all the real action is happening elsewhere ……

Don't think so?

Here are two facts for you.

• All the leading AI models are only months ahead of the open-source AI that is free to use and own. Medical AI with "fewer flaws than physician-written responses" - will be free & globally available by 2027.

• 66% of the Global South owns a smartphone. This means they can directly access AI.

Free Open-Source AI has been setting the standards, and it's likely to do so in medical AI, too. Furthermore, it won't just set the standards; it will be the gold standard.
