The amount of human codebase-understanding time that AIs can match has increased over time; the speaker estimates that 3.7 Sonnet or 3.5 Sonnet may have matched only about one day of understanding.

“But over time, the like amount of understanding AIs can match has gone up, right? So if we look at like 3.7 SONNET or 3.5 SONNET, maybe it could only match the equivalent of.”

“understanding a code base for like a day or something um but now you know ais are much better at like sort of building context about a task and so you can be like mythos i want you to really understand this code base and then um you know then implement this feature and it will like spawn a bajillion sub agents those sub agents will pour over a bunch of things it will like deliver a bunch of context back it will then like investigate a few things and it's not like amazing at doing this but it's like it can happen like really fast and it can work”
