Stable Horde

The Stable Horde: AI image generation for everyone through mutual aid

After completing the KoboldAI Horde, and onboarding into the KoboldAI client, I felt that there is a really big opening for doing a similar thing using the open sourced AI image generating model, Stable Diffusion. I already have the code for setting up a crowdsourcing cluster, so it shouldn’t take too much refactoring to make the same underlying code work with Stable Diffusion.

The first thing I had to do was figure out what is going to run on the workers. For this, I decided to reuse the stable-diffusion-webui fork by simply adding my bridge code on top of it (as it doesn’t provide a REST API like KoboldAI). Once I had a valid bridge, it was time to fork the Horde.

And thus, the Stable Horde was born!

It follows the same approach, where workers running some version of Stable Diffusion constantly poll for new generations to complete and then send it back to the horde to hand it over to their final destination. For now the stable horde is only handling fairly basic text2image generations, but since it’s based on the webui, I can tap into the features that added upstrean much easier, without having to develop them myself.

The code started as a fork of the Stable Horde, but has by now become my primary repo. In fact, with the addition of the second version of the REST API, I have decided to merge both Hordes into a single repository in order to better share code updates (because copying code from one repo to the other was driving me nuts!). This is coming soon, and it means that the Stable horde will always remain in parity with the KoboldAI horde from now on.

While there are other free image generation tools out there, I believe none is doing anything like what I am attempting. Most of these are based on providing free Stable Diffusion by eating the costs themselves, but with an undefined business plan. And when I see that, my suspicions are already raised, as a free service like that, typically means you’re the product! It also doesn’t help at all that they are not sharing the code behind them.

Now you might say, “But db0, your service is also free, how come the same criticism doesn’t apply to you?”. Which is a great question. The answer is that the reason the Stable Horde is free is because it’s volunteer based. That means, at the end of the day, someone is indeed paying for electricity (that is, myself primarily atm), but the point is that it is self-managing through people’s innate drive for mutual-aid.

That means that if I get a jump in popularity, which in turn exceeds the Horde’s current image generation capacity (and therefore slowing things down too much), the belief is that there will be enough people annoyed by the speed, that they will join their own power to the horde to benefit themselves with higher priority, but also everyone else.

And yes, there is always some amount of “small print”. While the Stable Horde is built on anarchistic principles of mutual aid and direct action, the fact is that we do not control the underlying workers. Therefore it is theoretically possible for people to act maliciously on the worker side, which is why I always warn people who will use the Horde that I cannot guarantee that nobody will see your prompts. So act accordingly.

Nevertheless, one of the things I’m offering is something that I just haven’t seen anyone else do for image gen, and that is a fully functioning RESTful API. The purpose of this it to further enable image generation for everyone in new and exciting ways that enable tools to use this capability without bankrupting their owners for a side hobby whose demand suddenly spiked. Already people have started creating some interesting tools, such as a weather app which uses the Stable Horde to generate a dynamic image representing the weather, based on environmental conditions.

On my end, I am interested in helping game developers figure out ways to implement AI into their games. For this purpose I have already released a Godot Add-On which allows you to request AI image generation during a game’s runtime. I have further used this add-on to create my own Stable Diffusion GUI client that can run on any device, without the need for a complicated install procedure, or a GPU.

All of this is just scratching the potential of what can be achieved by allowing automation to connect directly to Stable Diffusion (or text generation), and I’m excited to see what people will come up with in the future!
