On Sunday, a Reddit person named “Ugleh” posted an AI-generated picture of a spiral-shaped medieval village that quickly gained attention on social media for its outstanding geometric qualities. Comply with-up posts garnered much more reward, together with a tweet with over 145,000 likes. Ugleh created the photographs utilizing Stable Diffusion and a steering method referred to as ControlNet.
Reactions to the paintings on-line ranged from marvel and amazement to respect for growing one thing novel in generative AI artwork. “By no means seen photos like this. One thing new on the earth of artwork,” wrote one X person. “Tbh, I’ve seen a LOT of ai artwork, been on this area an extended very long time, and this is likely one of the most superior items I’ve ever seen. You probably did so good,” wrote AI artist Kali Yuga on X.
Maybe most notably, Y-Combinator co-founder and frequent social media tech commentator Paul Graham wrote, “This was the purpose the place AI-generated artwork handed the Turing Check for me.” Whereas Graham was referencing the Turing Test (which purports to check if a machine’s habits is indistinguishable from a human) as a metaphor moderately than actually, he was clearly impressed.
Not everybody was impressed, after all, with some X customers trying to pick apart the compositional components of the AI-generated spiral village. “It is good, however there are many selections a human would not make,” wrote a graphic designer named Trent. “Loads of the shadows aren’t right, and placing chimneys proper above home windows is mindless. Zooming in there are additionally the tell-tale noise patterns of AI artwork.”
In June, we covered a method that used the AI picture synthesis mannequin Steady Diffusion and ControlNet to create QR codes that appear like wealthy artworks, together with anime-inspired artwork. Ugleh took the identical neural community optimized for creating these QR codes (which themselves are geometric shapes) and fed simple images of spirals and checkerboard patterns into it as a substitute.
When guided by the immediate, “Medieval village scene with busy streets and chateau within the distance (masterpiece:1.4), (very best quality), (detailed),” ControlNet rendered scenes the place creative components of the photographs match the perceptual shapes of spirals and checkerboards. In a single picture, the clouds arc overhead and other people stand in a mild curve to match the spiral steering. In one other, squares of clouds, hedges, constructing faces, and a wagon cart make up a checkerboard-shaped scene.
The magic of ControlNet
So how does it work? We have lined Steady Diffusion often before. It is a neural community mannequin educated on thousands and thousands of pictures scraped from the Web. However the important thing right here is ControlNet, which first appeared in a analysis paper titled “Adding Conditional Control to Text-to-Image Diffusion Models” by Lvmin Zhang, Anyi Rao, and Maneesh Agrawala in February 2023, and shortly grew to become fashionable within the Steady Diffusion group.
Sometimes, a Steady Diffusion picture is created utilizing a textual content immediate (referred to as text2image) or a picture immediate (img2img). ControlNet introduces extra steering that may take the type of extracted data from a supply picture, together with pose detection, depth mapping, regular mapping, edge detection, and far more. Utilizing ControlNet, somebody producing AI paintings can far more intently replicate the form or pose of a topic in a picture.

Utilizing ControlNet and related prompts, it is simple to duplicate Ugleh’s work, and others have executed so to amusing impact, together with checkerboard anime characters, an animation, medieval village “goatse” (surprisingly secure for work), and a medieval village model of “Girl with a Pearl Earring.”
Regardless of the huge consideration and plenty of affords to show the paintings into NFTs, Ugleh has chosen to maintain a low profile for now. On X, he said, “I recognize all of the optimistic suggestions towards AI artwork, I don’t plan on creating wealth from my newest generations, and I can’t be doing any official interviews. I’m only a regular tech-savvy AI nerd who experimented with a brand new ControlNet method.”
If you wish to experiment with ControlNet, this site has a superb tutorial. Additionally, Ugleh posted a step-by-step workflow, together with the spiral and checkerboard template information, on Imgur.
Whereas the paintings is outstanding, current US copyright policy means that the photographs don’t meet the requirements to obtain copyright safety, so they could be within the public area. Whereas AI-generated paintings remains to be a contentious subject for a lot of on moral and authorized grounds, inventive fans proceed to push the boundaries of what’s potential for an unskilled or untrained practitioner utilizing these new instruments. It’s nonetheless unsure if or how the legislation will ever acknowledge the mandatory human spark of inspiration that makes works like these potential.
