Show HN: Twogether AI – Multi-Person Photo Generation API (twogether.ai)
We are launching a scalable API today that makes it possible to create multi-person portrait photos: which means the ability to create real-looking photos of any two persons interacting with each other in some way only by providing a prompt and the person's pose. Generating this kind of photo requires a deep understanding of the AI ecosystem, a knowledge gap many companies face. In order to make the photos look real with high consistency and for a low cost, chaining of many models is required, and an excellent understanding of how to tweak with the various params of each one.
We also handle the infrastructure required to generate the photos, which can be a challenge when dealt with alone, especially for companies with a small backend team (we can scale to thousands of requests per day and generate 100 photos in about 3 minutes). Our customers today use this technology for the following use cases: creating new photo albums from old-scanned albums, providing personalized content for user acquisition campaigns, enabling new kinds of experiences in physical venues, and creating humorous photos with celebrities.
There is a significant tradeoff between creating a robust abstraction layer on top of Stable Diffusion capabilities and providing customers with more control over various options. The API currently allows you to manipulate the following parameters: the pose of the couple (hugging, taking a selfie, etc.), their facial expressions, the style of the photo (realistic, cartoon, painting, etc.), as well as the location, theme, and outfits (e.g., ski vacation, on the beach)
We created a free demo app for you to view examples and try live: https://twogether.ai?source=hn (no user or payment needed). For full API access, contact me at yardenst@magicflow.ai. We can typically set you up within a day, but an onboarding session is required to ensure responsible API usage.

"Look, here's person X with Jeffrey Epstein", etc.
I would also be surprised if governments aren't also sewing distrust with their enemies by generating fakes of government officials in past random photos of graduating classes of military academies of foreign governments, just to sew chaos. And why stop there - are you a middle-management cartel member with low prospects for advancement? Find a higher ranking cartel member you want to get rid of, start generating their face in older real photos of FBI graduating classes. Who knows, a position might open.
It's a new world.
This seems to me like the worst possible thing to do. We already have a serious problem being able to determine what's true and what's not. A response like this would make the problem so much worse that it could pose an actual societal threat.
How did you get a license to use the image of these celebrities, let alone in commercialized deepfakes? Because that's kind of a hot topic right now and you're putting a giant target on your investors' assets if you didn't bother.
In Germany, a contract for such a service would be legally void.
(An example of this is the sale of radar detectors. Here, too, the companies claim that it’s the user’s responsibility not to use them for illegal purposes, i.e. speeding. But the courts don’t buy it. They say the companies know exactly what they selling, and they declare such contracts void. The fact that a user could, theoretically, use that detector in a way that would not be unlawful is irrelevant, since it’s empirically evident that the vast majority does not, and the very appeal of the product is precisely the unlawful behavior.)
That's not true if they cannot meet in person.
The legal aspects here are very interesting but I think they miss the point. This tech can be used to create photos with celebrities, but not only.
If you make a tool that makes copyright infringement easy, and you demonstrate infringing use in order to market it, you're really asking for trouble.
If you care about your startup and its survival, I strongly suggest you focus your marketing on legitimate B2B use cases and avoid showing off how great it is at making deepfakes. It's one thing to turn a blind eye to misuse of your technology and a whole different thing to explicitly promote misuse as a product feature.
I'm genuinely curious what you see the use case being 5-10 years from now. Or in the short term, which use case do you think is most compelling from a business perspective? Or is this just an entry point to much different uses of AI+Images in the future?
Do you see this as a B2B play or a B2C play?
Lots of AI startups doing various things with AI models, but I always have trouble seeing the business model vision. (Or maybe that doesn't matter, yet)
how are you handling licensing (use of celebrity or any other person's image) and copyright (original image is not from user, so is likely copyrighted by someone else)?
I'm trying to think of uses for this that aren't creepy ("manipulate... the pose of the couple... their facial expressions..."), dishonest ("photos... with celebrities..."), or dystopian ("creating new photo albums from old scanned albums... providing personalized content for user acquisition campaigns") and failing. If someone comes along and makes a fake photo of themself with a celebrity, that's great, but it's also a one-off novelty. What kind of non-sleazy recurring use is going to prompt people to pay for this?
IDK what you’re planning on charging for this, but it’s nothing that can’t be done for free on any device in a notebook already
