Nano Banana 2 has been my go-to AI image model for the past several months. Then GPT Image 2 dropped, and I had to see if it could actually compete. So I ran the same 15 prompts through both models at max quality and scored them on prompt adherence, text fidelity, spatial reasoning, style match, and anatomy. Final score: 9-4 in favor of GPT Image 2 (with 2 ties). I built this entire test using Claude Code inside Google Antigravity. Just brain dumped the idea, Claude Code wrote the Python, made the API calls, compiled everything into a 15-slide deck, and even did a first pass at judging (I pushed back on plenty of its calls). Where each model wins: - GPT Image 2 dominates text rendering (5-0), artistic and stylized work, and authentic photo realism that actually looks shot on a phone. - Nano Banana 2 still wins on spatial reasoning and a more polished, glossy photo aesthetic. For me, GPT Image 2 is my new pick for thumbnails, marketing assets, and community content. I'm officially back in the OpenAI ecosystem for image generation.
