It's just sort of crazy.
Like it's this work that would have taken just like a very long time as an engineer and now the model's like quite fast at it.
So one example of this is Cloud Code is built on the Bunn JavaScript runtime.
It's an open source JavaScript runtime.
It's an alternative to Node.js.
It's kind of a faster node.
Bunn was written in Zig.
Zig is a systems programming language.
It's kind of like C, it's very low level.
One of the problems with C, with Zig is you have to manually manage memory.
And so it's quite easy to run into situations where there's memory leaks and other memory management issues.
And so one thing that the bun team was doing is they were having Claude fuzz the code base and try to simulate and trigger memory leaks, and they were doing this for a long period of time.
They were able to find a lot of memory leaks.
It was sort of like a case at a time.
And that was kind of the capability of the model at the time was doing this fuzzing.
And then at some point, Jared on the team was like, okay, let's just rewrite it.
Maybe the model can do this.
And I think this is like one of these test problems that he kind of threw at the model with every new model generation.
And starting with Fable, the model started to be able to do it.
And so I think Opus 5 could do it as well.
