Continue in VScode has been great for dev. I have been using Claude. Results were really good, but recently more mixed, so now I swap between Claude 3.5 and OpenAI 4o. I find Continue does a pretty good job of keeping the context even if I swap models mid project. Never tried Llama only bc I guessed I didn't have the hardware for it, but if you're having success on an M1 then I'll give it a go too.
