Overview

Imagen 4 is Google DeepMind's dedicated text-to-image model, prized for a natural, photographic look and high-fidelity detail. It predates the Nano Banana line and remains a strong choice when you want clean, realistic photo aesthetics rather than the editing-and-reasoning focus of Gemini's image models.

An Imagen 4 Ultra tier pushes quality even higher for the most demanding photorealistic work. Available through Google AI Studio, Vertex AI and the Gemini app, Imagen 4 is a dependable, well-integrated option for teams already in Google's ecosystem.
