Amazon sellers are drowning in photo requirements. Main images, lifestyle shots, infographics, A+ content—the list never ends. Traditional photography costs $5,000 per product. AI promises to slash that to $5-20.
But which AI model actually delivers?
We tested Nano Banana against GPT-4 across every Amazon image type that matters. Here’s what we found.
What we tested:
- 1,000+ product images across 5 categories
- Same prompts for both models
- Real Amazon products from electronics to supplements
- Measured: quality, accuracy, Amazon compliance
Models compared:
- Nano Banana: Google’s newest image model (launched 2025)
- GPT-4: OpenAI’s established image generator
