Google shuts down all Imagen models on June 24: image generation moves to Gemini

My take: Google confirmed all Imagen models stop working on June 24, 2026, with Gemini 3.1 Flash Image and Gemini 3 Pro Image as the official replacements, now generally available. If your project uses the Imagen API, you have less than a week to migrate. It is part of the same platform shift retiring Gemini CLI today: Google is consolidating its AI offerings under the Gemini and Antigravity brands.
