What is the best AI model for fashion in 2026?
The AI fashion landscape is evolving rapidly, and choosing the right model can make or break your virtual photoshoots. Today, we're announcing Nanobana Pro (called Gemini Pro in our platform), the next iteration of our popular Gemini Flash model. But is it the best choice for your fashion photography needs? Let's find out.
In this comprehensive comparison, we put three leading AI models to the test: Seedream4, Gemini Flash (Nanobana), and the brand-new Nanobana Pro (Gemini Pro in our platform). We tested them with real-world scenarios: two-item outfits and challenging three-item combinations. The results might surprise you.

Verdict: All three models performed well with two items. However, Nanobana Pro showed noticeably better color accuracy, especially in rendering the rich brown tones of the fur coat and the deep black of the turtleneck.
Test 2: Three-Item Outfit Challenge
Now for the real test: combining three items — a fur coat, mini dress, and high boots. This scenario pushes AI models to their limits, requiring them to maintain composition, proportions, and style coherence across multiple garments.

The Verdict: Nanobana Pro Leads in 2026
Based on our comprehensive testing, Nanobana Pro (Gemini Pro in our platform) emerges as the best overall AI model for fashion photography in 2026. Here's why:
Photorealistic Quality
Nanobana Pro produces images that are virtually indistinguishable from professional photography. The lighting, textures, and overall composition rival real-world photoshoots.
Superior Color Fidelity
Whether it's the rich brown of a fur coat or the subtle tones of a mini dress, Nanobana Pro accurately reproduces colors, crucial for fashion brands showcasing their products.
Multi-Item Mastery
While Gemini Flash struggles and other models compromise on quality, Nanobana Pro maintains excellence even with 3-5 item combinations—essential for modern fashion marketing.
Perfect When It Hits
When Nanobana Pro successfully maintains avatar consistency (which it does increasingly well), the results are absolutely perfect—combining Seedream4's consistency with superior photo quality.
That said, Seedream4 remains unbeatable for guaranteed avatar consistency across large product catalogs, and Gemini Flash is still the speed champion for rapid iterations. The key is knowing when to use each tool in your AI fashion workflow.
