I wrote about what it’s like pairing with GPT-4 on a ruby Ruby at https://fly.io/ruby-dispatch/pairing-with-gpt-4/. Turns out the more you know about Ruby, the better your experience will be working with GPT-4 since it can send you down some pretty crazy paths. If you’re starting out, it can still give you pretty good results if you don’t ask it to build stuff for you. Overall, it’s more pleasant than using a search engine for help because you don’t have to wade through ads and SEO content that’s not helpful.
