FLUX VTO: Virtual Try-On at scale

What if every shopper could see themselves in an outfit before buying? What if that experience ran fast, at catalog scale, with the garment rendered exactly as it exists?

That's what FLUX VTO is built for. Apparel runs on emotional selling, and try-on is the digital version of that moment when a shopper pictures themselves in the piece and decides they want it.

Why try-on has stayed stuck in the demo phase

Virtual try-on has been promised for years, but production deployments are rare. The reasons are familiar to anyone who has evaluated the category. Models drift between generations, so identity, hair and pose shift in ways that make outputs unusable on a live product page. Garments fare no better: logos disappear, stitching degrades, prints render incorrectly and buttons vanish. Even when the geometry is right, the look is often wrong, with outputs that don't match a brand's contrast, highlights or aesthetic.

And underneath all of that sits the economics problem. Existing try-on models take 10 to 30 seconds per generation, which is too slow for interactive shopping and too expensive to run across a full catalog.

Any one of these is enough to keep try-on out of production. Together they explain why so few catalogs have shipped it.

What FLUX VTO does differently

FLUX VTO is engineered for real shopping experiences, not demos. It clears the bar on the three dimensions retailers actually care about.

Speed and cost that work at catalog scale. Generations complete in under four seconds, fast enough to feel interactive in a consumer flow. The model is also cheaper to run than comparable systems, which is what makes try-on viable across thousands of SKUs rather than a curated handful.

Fidelity on both sides of the image. Identity is preserved across generations, and garments come through with their logos, prints, stitching and hardware intact. The output looks like the person wearing the actual product, not a reinterpretation of it.

Styling flexibility. Apply up to four garments to a single model at once, transfer full outfits or individual pieces between models, and layer items such as a shirt under a jacket with correct interaction between them.

What to know before you build with it

See the look, explore the fit. FLUX VTO shows how a garment looks on a person, making it easy to explore styling, silhouette, and overall fit. Precise body and garment sizing is still evolving, so outputs are best used as visual styling guidance.

Default moderation is on. Swimwear and lingerie are not supported under the default policy. Uploads must also follow standard safety guidelines: no adult-oriented content, no child sexual abuse imagery, no non-consensual or sexually explicit content and no dangerous, derogatory or shocking material.

Use rights matter. Only upload photos of yourself or photos where you have explicit rights to use the subject's likeness.

Need to run this even faster? You can also self-host the model and run the try-on in sub-second response time!
