Episode notes
Combinatorial Explosion Blocks Manual Discovery
- Yamanaka factors are four proteins (OSKM) that reprogram cells but existing variants are highly inefficient.
- The combinatorial space of amino-acid sequences makes manual search effectively impossible.
Small LLMs Can Design Functional Proteins
- OpenAI fine-tuned a small 4B-parameter LLM on protein data to design new Yamanaka-factor variants.
- Labs validated that model-designed sequences produced large improvements in functional activity.
Hit Rates Jump From 0.1% To 30–50%
- Retro Biosciences tested model outputs and observed a roughly 30–50% functional hit rate from suggested variants.
- That contrasts sharply with prior ~0.1% success rates and implies huge search efficiency gains.
