One thing noteworthy is at the moment occurring within the AI synthesis neighborhood, although its significance could take some time to grow to be clear. Hobbyists are coaching generative AI video fashions to breed the likenesses of individuals, utilizing video-based LoRAs on Tencent’s not too long ago launched open supply Hunyuan Video framework.*

Within the video proven above, the likenesses of actresses Natalie Portman, Christina Hendricks and Scarlett Johansson, along with tech chief Elon Musk, have been skilled into comparatively small add-on information for the Hunyuan generative video system, which will be put in with out content material filters (equivalent to NSFW filters) on a person’s laptop.
The creator of the Christina Hendricks LoRA proven above states that solely 16 pictures from the Mad Males TV present have been wanted to develop the mannequin (which is a mere 307mb obtain); a number of posts from the Secure Diffusion neighborhood at Reddit and Discord affirm that LoRAs of this sort don’t require excessive quantities of coaching information, or excessive coaching occasions, generally.

Hunyuan LoRAs will be skilled on both static pictures or movies, although coaching on movies requires higher {hardware} assets and elevated coaching time.
The Hunyuan Video mannequin options 13 billion parameters, exceeding Sora’s 12 billion parameters, and much exceeding the less-capable Hunyuan-DiT mannequin launched to open supply in summer time of 2024, which has just one.5 billion parameters.
As was the case two and a half years in the past with Secure Diffusion and LoRA (see examples of Secure Diffusion 1.5’s ‘native’ celebrities right here), the inspiration mannequin in query has a much more restricted understanding of superstar personalities, in comparison with the extent of constancy that may be obtained by means of ‘ID-injected’ LoRA implementations.
Successfully, a personalized, personality-focused LoRA will get a ‘free journey’ on the numerous synthesis capabilities of the bottom Hunyuan mannequin, providing a notably more practical human synthesis than will be obtained both by 2017-era autoencoder deepfakes or by trying so as to add motion to static pictures through methods such because the feted LivePortrait.
All of the LoRAs depicted right here will be downloaded freely from the extremely well-liked Civit neighborhood, whereas the extra plentiful variety of older custom-made ‘static-image’ LoRAs may probably create ‘seed’ pictures for the video creation course of (i.e., image-to-video, a pending launch for Hunyuan Video, although workarounds are doable, for the second).

As I write, the Civit web site gives 128 search outcomes for ‘Hunyuan’*. Practically all of those are ultimately NSFW fashions; 22 depict celebrities; 18 are designed to facilitate the technology of hardcore pornography; and solely seven of them depict males moderately than girls.
So What’s New?
Because of the evolving nature of the time period deepfake, and restricted public understanding of the (fairly extreme) limitations of AI human video synthesis frameworks up to now, the importance of the Hunyuan LoRA shouldn’t be simple to grasp for an individual casually following the generative AI scene. Let’s overview among the key variations between Hunyuan LoRAs and prior approaches to identity-based AI video technology.
1: Unfettered Native Set up
A very powerful facet of Hunyuan Video is the truth that it may be downloaded regionally, and that it places a really highly effective and uncensored AI video technology system within the fingers of the informal person, in addition to the VFX neighborhood (to the extent that licenses could permit throughout geographical areas).
The final time this occurred was the appearance of the discharge to open supply of the Stability.ai Secure Diffusion mannequin in the summertime of 2022. At the moment, OpenAI’s DALL-E2 had captured the general public creativeness, although DALLE-2 was a paid service with notable restrictions (which grew over time).
When Secure Diffusion grew to become accessible, and Low-Rank Adaptation then made it doable to generate pictures of the identification of any individual (superstar or not), the massive locus of developer and client curiosity helped Secure Diffusion to eclipse the recognition of DALLE-2; although the latter was a extra succesful system out-of-the-box, its censorship routines have been seen as onerous by lots of its customers, and customization was not doable.
Arguably, the identical situation now applies between Sora and Hunyuan – or, extra precisely, between Sora-grade proprietary generative video methods, and open supply rivals, of which Hunyuan is the primary – however most likely not the final (right here, take into account that Flux would ultimately acquire vital floor on Secure Diffusion).
Customers who want to create Hunyuan LoRA output, however who lack successfully beefy tools, can, as ever, offload the GPU facet of coaching to on-line compute companies equivalent to RunPod. This isn’t the identical as creating AI movies at platforms equivalent to Kaiber or Kling, since there isn’t a semantic or image-based filtering (censoring) entailed in renting a web-based GPU to assist an in any other case native workflow.
2: No Want for ‘Host’ Movies and Excessive Effort
When deepfakes burst onto the scene on the finish of 2017, the anonymously-posted code would evolve into the mainstream forks DeepFaceLab and FaceSwap (in addition to the DeepFaceLive real-time deepfaking system).
This methodology required the painstaking curation of hundreds of face pictures of every identification to be swapped; the much less effort put into this stage, the much less efficient the mannequin could be. Moreover, coaching occasions diverse between 2-14 days, relying on accessible {hardware}, stressing even succesful methods in the long run.
When the mannequin was lastly prepared, it may solely impose faces into present video, and normally wanted a ‘goal’ (i.e., actual) identification that was shut in look to the superimposed identification.
Extra not too long ago, ROOP, LivePortrait and quite a few related frameworks have offered related performance with far much less effort, and infrequently with superior outcomes – however with no capability to generate correct full-body deepfakes – or any aspect aside from faces.

In contrast, Hunyuan LoRAs (and the same methods that can inevitably comply with) permit for unfettered creation of total worlds, together with full-body simulation of the user-trained LoRA identification.
3: Massively Improved Temporal Consistency
Temporal consistency has been the Holy Grail of diffusion video for a number of years now. Using a LoRA, along with apposite prompts, offers a Hunyuan video technology a relentless identification reference to stick to. In concept (these are early days), one may prepare a number of LoRAs of a selected identification, every carrying particular clothes.
Underneath these auspices, the clothes too is much less more likely to ‘mutate’ all through the course of a video technology (for the reason that generative system bases the following body on a really restricted window of prior frames).
(Alternatively, as with image-based LoRA methods, one can merely apply a number of LoRAs, equivalent to identification + costume LoRAs, to a single video technology)
4: Entry to the ‘Human Experiment’
As I not too long ago noticed, the proprietary and FAANG-level generative AI sector now seems to be so cautious of potential criticism referring to the human synthesis capabilities of its tasks, that precise folks hardly ever seem in mission pages for main bulletins and releases. As an alternative, associated publicity literature more and more tends to indicate ‘cute’ and in any other case ‘non-threatening’ topics in synthesized outcomes.
With the appearance of Hunyuan LoRAs, for the primary time, the neighborhood has a chance to push the boundaries of LDM-based human video synthesis in a extremely succesful (moderately than marginal) system, and to completely discover the topic that the majority pursuits the vast majority of us – folks.
Implications
Since a seek for ‘Hunyuan’ on the Civit neighborhood principally reveals superstar LoRAs and ‘hardcore’ LoRAs, the central implication of the appearance of Hunyuan LoRAs is that they are going to be used to create AI pornographic (or in any other case defamatory) movies of actual folks – celebs and unknowns alike.
For compliance functions, the hobbyists who create Hunyuan LoRAs and who experiment with them on various Discord servers are cautious to ban examples of actual folks from being posted. The fact is that even picture-based deepfakes at the moment are severely weaponized; and the prospect of including actually sensible movies into the combination could lastly justify the heightened fears which were recurrent within the media over the past seven years, and which have prompted new laws.
The Driving Pressure
As ever, porn stays the driving pressure for expertise. No matter our opinion of such utilization, this relentless engine of impetus drives advances within the state-of-the-art that may in the end profit extra mainstream adoption.
On this case, it’s doable that the worth will probably be increased than regular, for the reason that open-sourcing of hyper-realistic video creation has apparent implications for legal, political and moral misuse.
One Reddit group (which I can’t identify right here) devoted to AI technology of NSFW video content material has an related, open Discord server the place customers are refining ComfyUI workflows for Hunyuan-based video porn technology. Every day, customers publish examples of NSFW clips – lots of which may moderately be termed ‘excessive’, or at the very least straining the restrictions said in discussion board guidelines.
This neighborhood additionally maintains a considerable and well-developed GitHub repository that includes instruments that may obtain and course of pornographic movies, to supply coaching information for brand new fashions.
Since the preferred LoRA coach, Kohya-ss, now helps Hunyuan LoRA coaching, the limitations to entry for unbounded generative video coaching are reducing each day, together with the {hardware} necessities for Hunyuan coaching and video technology.
The essential facet of devoted coaching schemes for porn-based AI (moderately than identification-based fashions, equivalent to celebrities) is that a normal basis mannequin like Hunyuan shouldn’t be particularly skilled on NSFW output, and will due to this fact both carry out poorly when requested to generate NSFW content material, or fail to disentangle discovered ideas and associations in a performative or convincing method.
By creating fine-tuned NSFW basis fashions and LoRAs, will probably be more and more doable to mission skilled identities right into a devoted ‘porn’ video area; in any case, that is solely the video model of one thing that has already occurred for nonetheless pictures over the past two and a half years.
VFX
The massive enhance in temporal consistency that Hunyuan Video LoRAs supply is an apparent boon to the AI visible results business, which leans very closely on adapting open supply software program.
Although a Hunyuan Video LoRA strategy generates a complete body and atmosphere, VFX firms have nearly definitely begun to experiment with isolating the temporally-consistent human faces that may be obtained by this methodology, with a view to superimpose or combine faces into real-world supply footage.
Just like the hobbyist neighborhood, VFX firms should watch for Hunyuan Video’s image-to-video and video-to-video performance, which is probably probably the most helpful bridge between LoRA-driven, ID-based ‘deepfake’ content material; or else improvise, and use the interval to probe the outer capabilities of the framework and of potential variations, and even proprietary in-house forks of Hunyuan Video.
Although the license phrases for Hunyuan Video technically permit the depiction of actual people as long as permission is given, they prohibit its use within the EU, United Kingdom, and in South Korea. On the ‘stays in Vegas’ precept, this doesn’t essentially imply that Hunyuan Video won’t be utilized in these areas; nonetheless, the prospect of exterior information audits, to implement a rising laws round generative AI, may make such illicit utilization dangerous.
One different probably ambiguous space of the license phrases states:
‘If, on the Tencent Hunyuan model launch date, the month-to-month energetic customers of all services or products made accessible by or for Licensee is bigger than 100 million month-to-month energetic customers within the previous calendar month, You could request a license from Tencent, which Tencent could grant to You in its sole discretion, and You aren’t approved to train any of the rights underneath this Settlement until or till Tencent in any other case expressly grants You such rights.’
This clause is clearly aimed on the multitude of firms which are more likely to ‘intermediary’ Hunyuan Video for a comparatively tech-illiterate physique of customers, and who will probably be required to chop Tencent into the motion, above a sure ceiling of customers.
Whether or not or not the broad phrasing may additionally cowl oblique utilization (i.e., through the availability of Hunyuan-enabled visible results output in well-liked motion pictures and TV) might have clarification.
Conclusion
Since deepfake video has existed for a very long time, it will be simple to underestimate the importance of Hunyuan Video LoRA as an strategy to identification synthesis, and deepfaking; and to imagine that the developments at the moment manifesting on the Civit neighborhood, and at associated Discords and subreddits, symbolize a mere incremental nudge in the direction of actually controllable human video synthesis.
Extra doubtless is that the present efforts symbolize solely a fraction of Hunyuan Video’s potential to create utterly convincing full-body and full-environment deepfakes; as soon as the image-to-video element is launched (rumored to be occurring this month), a much more granular stage of generative energy will grow to be accessible to each the hobbyist {and professional} communities.
When Stability.ai launched Secure Diffusion in 2022, many observers couldn’t decide why the corporate would simply give away what was, on the time, such a invaluable and highly effective generative system. With Hunyuan Video, the revenue motive is constructed instantly into the license – albeit that it might show tough for Tencent to find out when an organization triggers the profit-sharing scheme.
In any case, the consequence is identical because it was in 2022: devoted growth communities have fashioned instantly and with intense fervor across the launch. Among the roads that these efforts will take within the subsequent 12 months are absolutely set to immediate new headlines.
