OpenAI Image 2.0 vs Nano Banana Pro - TESTED

A practical comparison of OpenAI Image 2.0 against Google's Gemini models (referred to as 'Nano Banana Pro' and Flash) across eight real-world landscaping visualization tasks. Tests include adding plants, removing trees, inserting fire pits, pergolas, water features, and swimming pools into photos of actual homes. OpenAI Image 2.0 generally produces more photorealistic results and better adheres to reference image assets, but is significantly slower and more expensive. Gemini Flash is faster and cheaper but less realistic, while Gemini Pro falls in between. The author plans to offer both a fast/cheap (Flash) and slow/quality (Image 2.0) option in their landscaping SaaS app.
