I'm a big believer in Claude. I've accomplished some huge productivity gains by leveraging it. That said, I can see places where the models are strong and weak. If you're doing react, or python. These models are incredible. C#, C++ they're not terrible. Rust though, it's not great. If your experience is exclusively trying to use it to write Rust, it doesn't matter if you're using o1, Claude or anything else. It's just not great at it yet.
