Imagen 4 Fast

by Google

Imagen 4 Fast is the speed-optimized variant of the Imagen 4 family, launched August 15, 2025. It delivers visual fidelity close to standard Imagen 4 while generating images up to roughly 10 times faster than Imagen 3, with individual generations completing in about 2.7 seconds, which suits high-volume pipelines and rapid creative iteration. The model maintains strong typography and text rendering across styles from photorealism and illustration to concept art, supports multiple aspect ratios and resolutions up to 2K, and watermarks every output with SynthID. It is built for developers and creative workflows where generation speed determines viability.
