    Sorry you have to deal with this. You can stay on Gemini Developer API. Here is what to change before December 1, 2026:

1. Check which models you call. Look for Gemini 4 Argon, Gemini 3.8 Flash and Gemini 3.6 Flash in your code and billing.
2. Work out the new cost. Multiply your monthly tokens by the new prices on the Gemini API price page.
3. Try a smaller model for simple jobs. Test a lighter model on easy tasks. Keep the bigger one only where it matters.
