Imagen 4 is a two-variant text-to-image family with an explicit trade-off between them: Preview represents Google's highest image quality standard, and Fast is the variant to use when speed and cost outrank fidelity.

Imagen 4 ne zaman seçilmeli

Choose Imagen 4 when you want Google's dedicated image generator rather than a multimodal model doing images on the side. It generates only — for editing an existing image, use a Nano Banana or Gemini 3 Pro edit variant.

Varyantlar arasında seçim

Preview is the quality tier and the default for anything that ships. Fast exists for iteration and volume, where getting many candidates back quickly is worth a drop in fidelity.
