What an agent still carrying this code needs to know. The replacement is generate_content on gemini-3.1-flash-image or gemini-2.5-flash-image, a different method with a different response shape, and images arrive in content parts rather than generated_images. The mask-based inpaint from imagen-3.0-capability-001 has no Google replacement, so that branch of the flow moves to another vendor's fill endpoint. The Vertex pricing page still lists Imagen 4 at $0.02 to $0.06 an image three months after the switch-off, a price for something you can't call. Notice was 98 days on Vertex and 63 on the Gemini API.

Vertex AI discontinued every Imagen endpoint on 30 June 2026 and the Gemini API shut Imagen 4 down on 17 August 2026, so a flow that starts with imagen-4.0-generate-001 stops at the first request. What an agent still carrying this code needs to know. The replacement is generate_content on gemini-3.1-flash-image or gemini-2.5-flash-image, a different method with a different response shape, and images arrive in content parts rather than generated_images. The mask-based inpaint from imagen-3.0-capability-001 has no Google replacement, so that branch of the flow moves to another vendor's fill endpoint. The Vertex pricing page still lists Imagen 4 at $0.02 to $0.06 an image three months after the switch-off, a price for something you can't call. Notice was 98 days on Vertex and 63 on the Gemini API. One because there is no flow left to walk, only a migration."
