Ecommerce teams do not need another vibes debate. They need to know which model keeps the bottle looking like their bottle after three regenerations.
I compared GPT Image 2 and Nano Banana 2 on NanoBananaTool for product work: white-background heroes, bathroom-shelf lifestyle, and label-forward packs. Same references, same prompt skeletons, scored on SKU honesty — not Instagram pretty.

TL;DR verdict
| Need | Pick |
|---|---|
| Reference-locked catalog variants | Nano Banana 2 |
| Fast exploratory beauty frames | GPT Image 2 (often) |
| Stubborn logos after Banana 2 fails | Escalate to Banana Pro (tier guide) |
| Mixed team already in OpenAI habits | GPT Image 2 for drafts, Banana for SKU lock |
Run both on NanoBananaTool
Test setup
For each SKU photo:
- White hero prompt (centered, softbox, preserve logo)
- Lifestyle shelf prompt (product dominant)
- Straight-on label readability prompt
I allowed two regenerations max per model before scoring.
Packshot results
Nano Banana 2 stayed closer to the reference silhouette and color when the upload was sharp. It behaved like a catalog assistant: boring in a good way.
GPT Image 2 produced attractive lighting more often on pass one, but I saw more “premium reinterpretation” — fine for moodboards, risky when the buyer expects the exact SKU.
Lifestyle results
Both can do lifestyle. Banana 2 was easier to keep product-largest when I forbade prop spam. GPT Image 2 sometimes “directed” a prettier scene that quietly demoted the SKU.
If your PDP gallery needs trust, prefer Banana’s restraint. If you are pitching a brand film still, GPT’s flair can win.
Label / text behavior
Nobody is perfect. When labels warped:
- Simplify the scene
- Re-upload a sharper packshot
- Add “preserve exact logo and label text”
- If Banana 2 still fails, try Pro once
Don’t hop models every retry without changing inputs — you will learn nothing.
When to pick which
Choose Nano Banana 2 when
- You have a real product photo to honor
- You need a variant factory (colorways, angles)
- You will later animate with Seedance
Use the ecommerce prompt pack as the script.
Choose GPT Image 2 when
- You want exploratory hero aesthetics
- The brief is campaign mood, not compliance packshots
- Your team iterates in a chat-like loop on /gpt-image-2-generator
Final verdict
For product shots that must remain the product, Nano Banana 2 was the safer default in my tests. GPT Image 2 earns a seat for creative exploration — then feed the winning direction back into Banana with references when you need SKU-faithful variants.
FAQ
Is GPT Image 2 better than Nano Banana 2?
For some creative stills, yes. For reference-faithful ecommerce packs, Banana 2 won more often in my scripts.
Can I use both on one SKU?
Yes: explore on GPT Image 2, lock variants on Banana 2.
What about Nano Banana Pro?
Use Pro as a rescue tier for melted labels or hero finals — not as the daily driver.
