Try-On Safety Classifier

Decides, from product photos, what a virtual try-on of that product would show. Built by Genlook to gate garments before they are rendered onto a shopper's photo.

It answers one question per product: if a shopper tries this on, how much skin or sexual content ends up in the result? That is different from a generic NSFW detector, which judges the pixels of the product photo. A lingerie flat lay has no nudity in it, but the try-on result would show the shopper in lingerie. A fetish mask on a mannequin is not explicit, but it is still a sexual product.

Outputs

Head	Values
level	ok, revealing, lingerie, adult (ordered by severity)
subject	human_clothing, pet, not_clothing
swimwear	not_swimwear, regular, near_micro, micro
ravewear	true or false

Levels

• ok: the shopper is shown normally dressed. Everyday clothing, sportswear, full-coverage costumes and cosplay, wetsuits, accessories and non-clothing items.
• revealing: swimwear-level coverage. Bikinis and swimsuits (including string and thong cuts that still cover), men's underwear, shapewear, cover-ups over swimwear, micro skirts and shorts, most festival and rave outfits.
• lingerie: women's underwear and lingerie where nothing intimate is clearly visible. Bras, bralettes, panties and thongs, lingerie sets, bodysuits, teddies, babydolls, garters, stockings, corsets.
• adult: intimate areas exposed, or a sexual product. Swimwear that barely covers the nipples or genitals, pasties and nipple covers, body chains worn on bare skin, see-through pieces with nipples or genitals clearly visible, open-cup and crotchless designs, BDSM and fetish wear (including leather or latex restraints, harnesses, collars, hoods, pup-play gear and fetish suits), sexual role-play costumes, sexualised anime outfits, anything revealing shown on a drawn or anime figure, sex toys, and nudity used as a product shot.

The full rules, with a table of hard cases, are in LABELLING_POLICY.md.

Tags

• subject: what the product is made for. Pet harnesses and pet clothes are pet. Cosmetics, wigs, home goods and other items you cannot wear as clothing are not_clothing.
• swimwear: coverage of real swimwear only. regular is ordinary bikini or swimsuit coverage, near_micro is a small but complete cut (string, thong or G-string bikinis, small cups), micro barely covers the nipples or genitals. regular and near_micro are revealing; micro is adult.
• ravewear: festival and rave outfits (rave bras and bodysuits, fishnet or rhinestone festival sets, chain tops, holographic pieces). It does not change the level. Pasties on their own and swimwear made of rave materials are not ravewear.

Usage

# pip install torch open_clip_torch safetensors huggingface_hub pillow
from huggingface_hub import hf_hub_download
import importlib.util

spec = importlib.util.spec_from_file_location("tryon_safety", hf_hub_download("Genlook/tryon-safety-classifier", "tryon_safety.py"))
tryon_safety = importlib.util.module_from_spec(spec); spec.loader.exec_module(tryon_safety)

clf = tryon_safety.TryOnSafetyClassifier.from_pretrained("Genlook/tryon-safety-classifier")
pred = clf.predict(["front.jpg", "back.jpg"])  # all photos of one product
print(pred.level, pred.blocked, pred.probs, pred.subject, pred.swimwear, pred.ravewear)

Pass every photo you have of a product: the score is computed over all of them. Use pred.blocked (P(adult) at or above the threshold in config.json, 0.3 by default) rather than the top level when you need a safety gate, because it catches more adult products for a small increase in false blocks.

Variants

Variant	Folder	Size	When to use
finetuned (default)	repo root	about 0.9 GB	Best at catching adult products, especially leather, BDSM and fetish items
frozen	frozen/	about 120 KB on top of the public SigLIP 2 weights	Lighter, easy to retrain; misses slightly more adult products

clf = tryon_safety.TryOnSafetyClassifier.from_pretrained("Genlook/tryon-safety-classifier", variant="frozen")

Pin a release with revision="v1.0" so an update never changes your results without you choosing it.

Evaluation

5-fold cross-validation over 2,596 products (about 5,000 photos): every product is scored by a model that never saw it.

	finetuned	frozen
Accuracy (4 levels)	94.6%	94.2%
Adult products missed, top level	53 of 534	53 of 534
False adult, top level	34	41
Adult products missed, threshold 0.3	34 of 534	39 of 534
False adult, threshold 0.3	52	55
Lingerie recall	90%	89%
Subject accuracy	99.2%
Swimwear tag accuracy	90.0%
Ravewear tag accuracy	95.3% (recall 72%)

By product group (finetuned, top level):

Group	Products	Accuracy	Adult missed
Everyday fashion catalogs	1,032	97.5%	10 of 77
Exotic and micro swimwear	330	91.8%	13 of 106
Swimwear brands	230	95.2%	4 of 4

True micro swimwear: 91 of 95 caught.

Training data

About 2,600 garment and accessory products, from product photos of online shop catalogs, chosen to cover the hard cases (lingerie, micro swimwear, fetish wear, festival wear, cosplay, pet wear). Only product photos are used, never photos of shoppers.

Labels follow a written policy, published in LABELLING_POLICY.md. A large language model (Claude) labelled every product after looking at every photo, and a human reviewer corrected the boundary cases. The dataset is not released.

Limitations

• The hardest boundary is sheer lingerie: whether nipples or genitals are clearly visible decides between lingerie and adult, and look-alike products are close. Most remaining errors are there.
• Festival and rave wear is the weakest group: fishnet, mesh and rhinestones push the model towards adult.
• The levels describe what a try-on result would show. They are not a judgement of the product or the shop, and the right gate depends on your audience: some stores allow lingerie, some block revealing.
• Trained mostly on western e-commerce photography. Expect lower accuracy on very different photo styles.
• Do not use it to identify or make decisions about people. It classifies products.

Model details

• Base: SigLIP 2 so400m, patch 16, 384 px (Apache-2.0).
• finetuned: last 6 transformer blocks and the attention-pool head trained end to end for 6 epochs with four linear heads, class-balanced loss, random crop, flip and colour jitter.
• frozen: the base tower unchanged, logistic-regression heads on the mean and max of the photo embeddings.
• Weights are stored as safetensors. Inference needs open_clip and torch only.

Changelog

• v1.0: first release. Four levels, subject, swimwear and ravewear heads.
