Why non-thinking model? Also 5-20 minutes?! I guess I don’t know what kind of code you are writing but for my web app backends/frontends planning takes like 2-5 minutes tops with Sonnet and I have yet to feel the need to even try Opus.
I probably write overly detailed starting prompts but it means I get pretty aligned results. It does take longer but I try to think through the implementation first before the planning starts.
