I use a quota monitor and grind out code on Gemini 3 flash. Only go to sonnet or pro is there's issues flash can't deal with or I have a critical architecture I need nailed on the first try.
I still review every line generated.
Gemini 3.1 pro on the web interface still works if my problems are scoped to a single module or two and my better model quotas are exhausted in the IDE.
For $7 over what I was already paying for storage, primarily using flash is still a good development experience for me.
