I was mainly doing python with gpt4, but now im working on an android project, so kotlin. Gpt4 wasn’t much use for kotlin, especially for questions involving more than a couple files. Sonnet is crushing it though, even when I give it 2k+ LoC. I’d say I’ve done about 2 months of pre-llm work in the last week, granted I am no professional, just a hobbyist.
