I find GPT-4 pretty amazing at coding myself. I have learnt basic R language + a particular package within it, enough to solve an emergency issue that barred us from launching a product for a coding competition within 24 hours of only having heard of the language before, just barely meeting our deadline. The team was amazed and I could never have done it without GPT-4.
Otherwise I'm regularly coding with it as an assistant while it's not always 100% correct, it's often decimating the time especially when I can request things like a website skeleton layout and it just seamlessly doing it all using CSS flow layouts and whatnot. I ask it to implement a Javascript library for a chat-style interface with bubbles and just bam it's there, even adapted for existing code.
I'll still have to debug and I _will_ still find issues occasionally but the win is still often enormous for me.
ChatGPT 3.5 though. That's mostly just a toy, yes.
I love it (gpt4) for code. At least for Python and Typescript.
It doesn’t always get it perfect, but it gets a lot right. Having enough experience in the field makes it easy to know when it’s right or not. Then you either ask again with more context and information, or do it yourself.
Overall, it’s definitely increased my productivity.
