Danbooru official, which became the source of learning about illustration automatic generation AI 'NovelAI', announced a statement

Image generation AIs such as Stable Diffusion and Midjourney learn from datasets made up of a large number of images. NovelAI, which has become a hot topic for its ability to generate high-precision 2D illustrations, is said to include many images from the overseas 2D image site Danbooru in its learned datasets. Danbooru's official management team has issued a statement about NovelAI.

Danbooru is a site where you can post and share 2D illustrations, and it is especially popular for its abundant tags that indicate the content drawn in the illustrations and excellent searchability. However, it is a problem that many of the 2D illustrations uploaded to Danbooru are reprints of works posted on SNS such as Pixiv and Twitter.

The management of Danbooru says, ``Please send an email to [email protected] to request the deletion of the image. I would appreciate it if you could do it, ”he said, and said that he would respond to unauthorized reprints.

In addition, Danbooru issued the following statement regarding NovelAI, which uses Danbooru images as a dataset.

First of all, we want to make it clear that we are not affiliated with NovelAI and that we do not endorse or even condone what they are doing.
For artists who do not want NovelAI to use their drawings, the most efficient way is to contact NovelAI directly, delete their drawings from the company's learning data, and create AI art. It is a request to exclude your name or pseudonym from the 'prompt' (instructive text) that the user enters.
At this point, NovelAI's learning data has already been completed, and due to the structure of the AI model, even if you delete a picture from Danbooru, the information learned from that picture will not automatically disappear from NovelAI's hand, so please be careful. please give me.

Even if a picture has never been uploaded to Danbooru, it is highly likely that it will be collected by NovelAI etc. once it is posted on Pixiv or Twitter.
In other words, I would appreciate it if you could think that the pictures that NovelAI can collect from Danbooru can also be collected from Pixiv and Twitter.
In the first place, most AI art generation services such as NovelAI create their own AI models based on Stable Diffusion, the software provided by Stability.ai.
Stable Diffusion itself was created by collecting 5 billion pictures as training data from various sources on the Internet.
That means not only Twitter, Pixiv, ArtStation, DeviantArt, and other sites that artists often use, but also Reddit, Pinterest, Facebook, Google image search, and countless other sites.
If it is a picture taken in Stable Diffusion, it seems that even if it is deleted from Danbooru now, the effect will be thin.

In other words, what I would like artists to understand is that the AI model of the AI art generation service is learning not only from Danbooru, but from the entire Internet.
As long as the pictures are open to the public somewhere on the Internet, there is always the danger that they will be taken up as learning data.
There is no way to prevent it other than contacting the developer of the AI model.

Danbooru management introduces a site where you can check whether your work is being used for learning image generation AI.

``Have I Been Trained?'' that allows you to search whether your work has been used arbitrarily for image generation AI-GIGAZINE

Also, after declaring that you do not want your picture to be used for AI learning, you can notify the AI developer by using the following service.


There are many posts on Twitter about what kind of illustrations can be generated with NovelAI.

There are many other models that use Danbooru images as datasets. There are various types of derived models of Stable Diffusion, and which model is learning using what data set is summarized in the following article.

Also, NovelAI was originally an AI that automatically generates novels, and illustration generation is just one of the functions. Regarding the image generation part, it is said that it implements its own algorithm while following Stable Diffusion. However, unlike Stable Diffusion, which is open source and open to the public, NovelAI's source is not open to the public.
