Flux 1.1 Pro from Black Forest Labs has quietly become the default for high-end product photography in 2026 — but how does it actually hold up at scale? We ran it through 500 real Shopify product photos to find out.
What we tested
Five verticals. Same prompt structure. Same conditioning image. Same aspect ratio. We asked one question: would a brand actually ship this without retouching?

Where Flux 1.1 Pro wins
For supplements and beauty, 78% of generations were ad-ready out of the box — meaning a marketer could drop them straight into a Meta ad without a retouch pass.
Where it still drifts
- Hands holding the product — still an industry-wide weakness, Flux included.
- Tiny brand text on labels — gets blurry below ~30 pixels.
- Identity drift on round-shaped products — the silhouette stays right but small label details shift.
Cost and speed
| Metric | Flux 1.1 Pro | Nano Banana |
|---|---|---|
| Cost / image | $0.040 | $0.039 |
| Avg time | 4.8s | 5.8s |
| Identity preservation (1–10) | 7.8 | 8.6 |
Flux is slightly faster and cheaper, but Nano Banana wins on identity preservation when you need the product to stay perfectly on-model.

Verdict
Flux 1.1 Pro is the safest single pick if you have to choose just one image model for a beauty or supplements brand. For everything else, multi-model routing is the move.
