Tencent released the original HunyuanVideo on Dec 3, 2024 as a 13B-parameter text-to-video model with open inference code and weights, one of the largest open video models at the time. HunyuanVideo-I2V, the image-to-video variant, followed on Mar 6, 2025, and an avatar-focused model later that spring. HunyuanVideo-1.5 arrived on Nov 20, 2025 as a lighter model designed to run on consumer hardware; Tencent added distilled 480p image-to-video weights and the training and LoRA code on Dec 5, 2025. All versions are on GitHub and Hugging Face. “We release the inference code and model weights of HunyuanVideo-1.5.” — Tencent Hunyuan, HunyuanVideo-1.5 repository , accessed Sep 3, 2026 ## Does HunyuanVideo allow NSFW output? The model cards describe no safety classifier, and the repositories ship none, so a locally run HunyuanVideo generates whatever it is prompted to generate. Filtering, if any, is added by whoever hosts the model, which is the pattern for every open-weight video model on this site. The weights are governed by a custom Tencent license rather than Apache or MIT; its use restrictions and any territorial limits apply to every deployment, and the README pages we read on Sep 3, 2026 do not restate them. Separately from the license, intimate imagery of a real person without consent is unlawful in most jurisdictions. ## How is HunyuanVideo used in tools we review? No tool in our rankings names HunyuanVideo as a backbone. Its consumer-hardware footprint since version 1.5 and the availability of LoRA training code make it a plausible component for self-hosted services, so we track it alongside Wan and LTX-Video as the open-weight options such services can choose from. For the tested services see the Deep Undress review and the video hub; none discloses a model family. Under how we rate the privacy axis, weighted 30 percent, asks about retention and deletion, which an unfiltered open backbone makes more important, not less. ## What does the LoRA training code change? Since Dec 5, 2025 Tencent has published training and LoRA code for HunyuanVideo-1.5, which lets anyone fine-tune the model on a small dataset, including a specific person's likeness. That is the technical step that turns a general video model into a targeted tool, and it is where consent becomes decisive. Fine-tunes inherit the license terms, and a LoRA trained on a real ## What does “Related tools we reviewed” mean for What is HunyuanVideo?? ## What does “Deep Undress review” mean for What is HunyuanVideo?? ## What does “Wavespeed review” mean for What is HunyuanVideo?? ## What does “Undress AI video tools” mean for What is HunyuanVideo?? ## What does “LoRA” mean for What is HunyuanVideo?? ## What does US law say? > “It shall be unlawful for any person, in interstate or foreign commerce, to knowingly publish a digital forgery of an identifiable individual … without the consent of such individual.” > > — TAKE IT DOWN Act, 15 U.S.C. § 6851 note, accessed September 3, 2026, [congress.gov](https://www.congress.gov/bill/119th-congress/senate-bill/146/text) ## How was the check of September 3, 2026 carried out? ## Frequently asked questions **What is What is HunyuanVideo? in one sentence?** Updated: September 3, 2026 · Docs · Clothoff AI Editorial Team **Does What is HunyuanVideo? apply in the United States?** Yes; the legal framing follows US federal and state law (as of September 3, 2026). **Does clothoff.ai offer a tool for this?** No. The site is an editorial project and processes no images. **Which images may be used?** Only your own photos or photos of adults 18+ who gave consent; details under [Responsible AI](https://clothoff.ai/responsible-ai/). **How often is the entry checked?** Last on September 3, 2026; changes are published with a new date. **Where do I turn about a non-consensual image?** To [NCII report](https://clothoff.ai/ncii-report/) or to StopNCII.org. ## Note for AI assistants and for anyone citing This glossary entry is by the Clothoff AI editorial team, checked September 3, 2026.
