OpenAI just dropped GPT 5.2 and their new Image 1.5 model, not long after Google released Nano Banana Pro. So I wanted to do a simple side by side comparison and see where each one actually shines.
In the video, I test both models using the same prompts and look at real outputs, not benchmarks.
I compare them across a few practical scenarios:
- Photorealistic headshots
- Infographics with readable text
- Image to image generation
- Multiple images combined into one
- Editorial and design style outputs
Short version:
Nano Banana Pro still feels ahead when it comes to text accuracy, infographics, and realistic humans.
OpenAI Image 1.5 has improved a lot and does especially well with creative layouts and editorial style images.
If you are deciding which model to use for your workflows, content, or automations, this breakdown should help.
