Since Gemini 3.8 Flash release, I've been largely using that for my coding ttasks. The architectureand design work I use Opus, but the rest of the work is done via Gemini 3.8. I don'thave to worry aboutweekly limits even on the $20 plan. I get down to about 10% weekly limit before it resets. Currently I'm building my own generative modeling + aero sim package largely using Gemini and it's been working great.
