tldr: >-
  IDM-VTON is the best-known open-source try-on model, and it is exactly that:
  research code under a non-commercial license, unmaintained since 2024. Genlook
  is a finished commercial try-on API. This page is really about what production
  requires.

<ProseSection label="03 — The real difference" title="The license is the answer, the ops are the reason">
IDM-VTON deserves its reputation. The ECCV 2024 paper moved the field, the fabric and color fidelity still hold up, and the weights are a download away. For studying how diffusion try-on works, it remains one of the first models worth reproducing.

Production is where it stops. The license is CC BY-NC-SA: non-commercial use only, stated plainly on the model pages that host it. Shipping IDM-VTON output in a paid product is a license violation, not a gray area. Suppose the license were not the issue: you would still inherit a preprocessing pipeline of human parsing and DensePose, auto-masking that only handles tops without manual mask work, 17 to 38 seconds per image on an A100, and an upstream repository with no substantive commits since April 2024. Issues filed against it today go unanswered. Every operational gap, hosting, storage, moderation, retries, is yours to fill around a model nobody maintains.

### How Genlook handles it

Genlook sells the finished layer: a standalone try-on API, commercially licensed end to end, always warm at 9.3 seconds median, covering tops, bottoms, dresses, shoes and accessories through one endpoint with no masks and no preprocessing. Results are stored, webhooks are built in, and end-user data gets a lifecycle: user records, auto-expiring images, a deletion endpoint for privacy requests. The engine stays current with the state of the art behind the same contract, so you always get the best available result instead of waiting on a dormant repo. A try-on costs a predictable $0.08 flat, $0.065 at volume, with no GPUs on your invoice and no hosting or scaling to run.

Reproduce IDM-VTON to learn the field. When real users are on the other end, use an API that is licensed, maintained and finished.

<Faq label="06 — FAQ" title="Questions, answered.">
  <FaqItem question="Can I really not use IDM-VTON commercially?">
Not under its published license. The code and checkpoints carry CC BY-NC-SA terms, and the hosted model pages state "Non-Commercial use only". A commercial product is commercial use. Unless you separately license the model from its authors, shipping it is a compliance problem waiting for an email.
  </FaqItem>
  <FaqItem question="Isn't running IDM-VTON basically free?">
The compute is cheap: a few cents per image on a rented A100 through hosts like Replicate. The rest is not. You pay in preprocessing pipeline work, manual masking for anything that is not a top, idle GPU time or cold starts, storage and moderation you build yourself, and engineering time against a repo that stopped moving in April 2024. And the output still cannot ship commercially.
  </FaqItem>
  <FaqItem question="Is IDM-VTON still maintained?">
Effectively no. The upstream repository's last substantive commits date to April 2024, and issues filed since have gone largely unanswered. The activity around it lives in third-party wrappers: ComfyUI nodes, hosted inference pages, community re-uploads. None of them change the license or maintain the model itself.
  </FaqItem>
  <FaqItem question="When is IDM-VTON the right choice?">
For research and learning, genuinely. It is one of the most instructive open try-on models to reproduce, benchmark against, or build academic work on. That is exactly what its license permits, and within those bounds it is a fine choice.
  </FaqItem>
  <FaqItem question="Can I test Genlook before committing?">
Yes. Keys are self-serve, new accounts start with 5 free credits, and the quickstart is two REST calls. Run the same product photos through the IDM-VTON demo and through Genlook, and compare fidelity, speed and the amount of setup each required.
