I'm sure. It kinda depends though, I've seen good stuff and bad stuff (including in Rust, including cryptography). This case did have the advantage of being a pure implementation and not "new reasoning" task, though a hard one. I've seen more good than bad results. Also, this is the latest gen. I don't know if gpt5 is particularly good compared with others.

It's not reliable generally but if you know what you're doing it's super effective.
