Claude 3.5 was remarkably good at writing code. If Claude 3.7 and Claude 4 are just incremental improvements on that then even better!

I actually think they're a lot more than incremental. 3.7 introduced "thinking" mode and 4 doubled down on that and thinking/reasoning/whatever-you-want-to-call-it is particularly good at code challenges.

As always, if you're not getting great results out of coding LLMs it's likely you haven't spent several months iterating on your prompting techniques to figure out what works best for your style of development.
