Imagen 4 Ultra vs GPT Image 2
Google vs OpenAI premium image models. Imagen 4 Ultra at 8 credits vs GPT Image 2 at 20 credits.
Imagen 4 Ultra from Google and GPT Image 2 from OpenAI represent two different approaches to AI image generation. Google's highest quality image model with enhanced detail, richer lighting, and fewer artifacts. On the other side, openAI's latest image model with state-of-the-art photorealism, pixel-perfect text rendering, and flexible resolutions up to 4K.
At 8 credits, Imagen 4 Ultra costs 12 credits less than GPT Image 2 (20 credits). The question is whether the extra cost of GPT Image 2 translates into meaningfully better results for your use case. For hero images, production-quality output, high-fidelity generation, Imagen 4 Ultra is hard to beat at its price point. But if you need highest quality generation, text rendering, photorealism, product photography, GPT Image 2 may justify the premium.
Updated May 2026
