Which AI Image Model Should You Use in Astria? (2026 Guide)
Start with GPT Image 2.5 when you want a polished, reference-led fashion campaign frame. Sunburst is the more aggressive editorial variant; Flare gives the garment and accessory more room. GPT Image 2, Nano Banana 2, Seedream 5 Pro, Muse, and MAI Image remain useful routes when their visible tradeoffs fit the job.
The guidance below comes from one controlled Sloane/dress/bag brief. It is deliberately narrower than the earlier mixed-source scorecard, which has been retired from the public article family.
Model-selection table
| If the approval risk is… | Start with… | Evidence from this matched cell |
|---|---|---|
| Strong editorial energy | GPT Image 2.5 Sunburst | Most forceful diagonal pose and flash-led crop |
| Complete garment and accessory framing | GPT Image 2.5 Flare | Full bag with a steadier campaign composition |
| Accessory presence | Nano Banana 2 | Largest, clearest treatment of the circular-detail bag |
| A polished established GPT route | GPT Image 2 | Strong art direction, identity, and garment handling |
| A complete 2K fashion route | Seedream 5 Pro | Full look and bag, with slightly softer identity |
| Reference separation despite canvas flexibility | Muse | Coherent person, dress, and bag; returned 3:2 instead of 16:9 |
| Native-resolution MAI comparison | MAI-Image-2.6 | Strong likeness and distinct references at 1365×768 |
| Faster MAI exploration | MAI-Image-2.6-Flash | Useful composition with simplified surface detail at 1365×768 |
These are starting points, not global rankings. The right default is the result that survives the actual identity, SKU, accessory, and delivery format.
The references behind the guidance
All compatible models received the approved reference set from Maison Urban prompt 46557199, copied into workspace 896 (Articles).
The Sloane source is below the preferred 1600px gate and is disclosed as such. The dress and bag pass the long-edge gate. No model received a text-only substitute.
Representative matched results
The full comparison also includes both MAI variants and the exact shared prompt.
A simple routing workflow
- Choose the model whose visible treatment best matches the job.
- Run the actual identity, garment, and accessory references together.
- Keep prompt, aspect ratio, resolution policy, and output count fixed for a comparison.
- Review the original downloads for identity, garment construction, and accessory geometry.
- Treat web derivatives as presentation assets, not as proof of master resolution.
- Approve a setup before multiplying it across a collection.
Bottom line
GPT Image 2.5 is the headline route in the current article family because both variants delivered strong, high-resolution, reference-led fashion frames. The other endpoints remain useful when their specific composition, accessory treatment, canvas behavior, or native resolution fits the production need.
