Calls to the model gemini-1.5-flash-8b-001 on Gemini API stopped working on September 29, 2025.
What to use instead of gemini-1.5-flash-8b-001
Move to gemini-3.5-flash-lite. Our suggestion, not Google's: the release notes that record the shutdown name no successor. Flash-Lite is the tier that took over the small, cheap slot after 1.5.
