Imagen 4 Ultra

by Google

Imagen 4 Ultra is the quality-focused tier of the Imagen 4 family, built for creative work demanding the highest level of detail and strict adherence to prompts. It generates images at up to 2K resolution with high fidelity and compositional accuracy. Where the standard Imagen 4 model balances quality and speed, Ultra targets precision. It delivers closely aligned results when a creative vision calls for intricate detail, complex compositions, and faithful interpretation of nuanced instructions. Images generated with Ultra include imperceptible SynthID watermarks, serving design workflows where quality is paramount.
