Stopped working
Calls to the model imagen-4.0-generate-001 on Gemini API stopped working on August 17, 2026.
What to use instead of imagen-4.0-generate-001
Move to gemini-nano-banana-2.1, recommended by Google.
Nano Banana is called with generate_content (generateContent), not generate_images, and returns the image as a content part holding the image data instead of Imagen's generated-images response object.
