“The nice thing about structure prediction is there is a ground truth that you can compare against. For design, you, don't really have that. You're like, here's some new, like disease molecule. Give me a binder for that. And like, if you want to know if this thing really binds you have to send it off to the lab and wait a while. For structure prediction, you can be like, all right, the model hasn't seen this sequence before. It's never seen anything close. Does it actually like fold up into the correct shape? And we can just kind of hold that out of the dataset and check. So I think I've always thought of structure prediction as this really nice speed run kind of benchmark to like validate ideas on.”

McPartlon: Chai's research team largely lacks formal biology backgrounds
“Like the whole research team at CHI except for me and Kevin, really like we're the only people with quote bio background. Even still, like we're pretty far removed. So I think like we try to like look at every problem as a core ML problem.”

McPartlon: Chai-2 generated binders for 25 targets with 20% hit rate
“So we designed antibodies to 50 targets for that paper, got binders to about half of them with being on average around a 20% hit rate for binding.”

McPartlon: Chai-2 achieved 0.33 angstrom error in cryo-EM testing
“And in this case, it was a 0.33 angstrom error, which is one third the width of an atom.”
