Get familiar with Imagen 4.0 Ultra and GPT Image 1.5
Imagen 4.0 Ultra focuses on realism and physical accuracy. It produces highly detailed images with natural lighting, accurate shadows, and realistic textures that closely resemble real-world photography. GPT Image 1.5 focuses on flexibility, generating images across a wide range of styles while maintaining strong prompt understanding and consistent composition across different creative tasks.
Explore image quality: photorealism vs creative versatility
The difference becomes clear in how each model handles visual output. Imagen 4.0 Ultra excels at photorealistic rendering, producing images with convincing lighting behavior, material detail, and depth that feel grounded in reality. GPT Image 1.5 also produces strong visuals, but spreads its capabilities across multiple styles, making it more adaptable for illustration, design, and mixed creative formats.
Understand prompt control and composition
Prompt handling is where GPT Image 1.5 stands out. It follows complex instructions closely, ensuring that elements, colors, and layouts appear exactly as described. Imagen 4.0 Ultra also performs well with prompts, particularly in realistic scenes, but focuses more on interpreting visual accuracy than handling highly structured instructions. Both models produce strong compositions, but GPT Image offers slightly more control in multi-element scenarios.
See how the style range and workflow differ
Creative workflows differ based on how each model is used. GPT Image 1.5 supports a wide range of visual styles, making it suitable for projects that require switching between design, illustration, and photography. Imagen 4.0 Ultra is more specialized, delivering consistent high-fidelity output for realistic scenes where lighting and material behavior matter most.
