The speaker sees models' improved ability to debug, retry, and assess what is working as the biggest recent change in computer use: models previously started tasks reliably but often ran into problems.

“And now the models just in the last one year have become extraordinarily capable of computer use. I think the biggest delta that I see is before they could like reliably start tasks, but then they would run into problems and now they're really good at debugging. They're really good at trying again,”

“introspecting what is and isn't working.”
