In 2026, two models dominate the AI image conversation: GPT Image 2 by OpenAI and Nano Banana Pro by Google DeepMind. We tested both with 50 prompts varying style, complexity and references. Here's the verdict.
Quality side-by-side
Photo-realism: Nano Banana Pro renders more detailed textures, especially portraits and natural-light scenes. GPT Image 2 is good but has a more polished/CGI look.
In-image text: GPT Image 2 wins — generates signage, logos and titles without distortion. Nano Banana Pro improved a lot but still misses on long copy.
