OpenAI just notched a real biology win: a tiny 4B-parameter model (“GPT-4B-micro”) designed Yamanaka-factor protein variants that jumped lab hit rates from ~0.1% to 30–50% in tests with Retro Biosciences. We unpack how a small, domain-tuned GPT can actually reprogram cells, what partial vs full age reversal could mean, and why this points to personalized longevity. We contrast OpenAI’s approach with Google’s AlphaFold push and outline the road from early results to therapies (think years of trials, roughly 7–12). If you want the fountain-of-youth story grounded in mechanisms, math, and lab-verified results, this episode is it.
