Imagen 4 is Google's latest text-to-image generation model, delivering significant improvements in photorealism, fine detail, typography, and style range over its predecessor. It generates images at up to 2K resolution up to 10 times faster than Imagen 3, with markedly better text rendering — handling longer strings, accurate spelling, and complex layouts for comics, packaging, logos, and product design. All generated images include SynthID, an invisible digital watermark for AI-generated content identification.
