Imagen 4

Deprecated

Text-to-image model billed per image ($0.04 per image, paid tier only — no free tier), so the per-token price fields are N/A. Google's pricing-page banner: "Imagen 4 models (imagen-4.0-generate-001, imagen-4.0-ultra-generate-001, imagen-4.0-fast-generate-001) are deprecated and will be shut down on August 17, 2026; migrate to Gemini 2.5 Flash Image to avoid service disruption." The deprecations table names gemini-3.1-flash-image as the recommended replacement instead, and Gemini 2.5 Flash Image is itself deprecated (shutdown 2026-10-02) — replacement follows the table, which carries the field as data. Google publishes shutdown dates as "the earliest possible dates on which a model might be retired"; already-shut-down models are marked with a grey row on the deprecations page.

Imagen 4 by Google is tracked live in our LLM catalog. It is deprecated, shutting down 17 Aug 2026; the recommended replacement is Gemini 3.1 Flash Image (Nano Banana 2).
