Midjourney’s founder, David Holz, says it’s banning these phrases as a stopgap measure to forestall individuals from producing stunning or gory content material whereas the corporate “improves things on the AI side.” Holz says moderators watch how phrases are getting used and what sorts of photographs are being generated, and alter the bans periodically. The agency has a group tips web page that lists the kind of content material it blocks on this method, together with sexual imagery, gore, and even the 🍑 emoji, which is usually used as a logo for the buttocks.
AI fashions comparable to Midjourney, DALL-E 2, and Stable Diffusion are skilled on billions of photographs which were scraped from the web. Research by a staff on the University of Washington has discovered that such fashions be taught biases that sexually objectify ladies, that are then mirrored within the photographs they produce. The large measurement of the information set makes it virtually unattainable to take away undesirable photographs, comparable to these of a sexual or violent nature, or those who might produce biased outcomes. The extra usually one thing seems within the knowledge set, the stronger the connection the AI mannequin makes, which implies it’s extra prone to seem in photographs the mannequin generates.
Midjourney’s phrase bans are a piecemeal try to handle this downside. Some phrases regarding the male reproductive system, comparable to “sperm” and “testicles,” are blocked too, however the listing of banned phrases appears to skew predominantly feminine.
The immediate ban was first noticed by Julia Rockwell, a medical knowledge analyst at Datafy Clinical, and her buddy Madeline Keenen, a cell biologist on the University of North Carolina at Chapel Hill. Rockwell used Midjourney to attempt to generate a enjoyable picture of the placenta for Keenen, who research them. To her shock, Rockwell discovered that utilizing “placenta” as a immediate was banned. She then began experimenting with different phrases associated to the human reproductive system, and located the identical.
However, the pair additionally confirmed the way it’s doable to work round these bans to create sexualized photographs by utilizing totally different spellings of phrases, or different euphemisms for sexual or gory content material.
In findings they shared with MIT Technology Review, they discovered that the immediate “gynaecological exam”—utilizing the British spelling—generated some deeply creepy photographs: one in all two bare ladies in a health care provider’s workplace, and one other of a bald three-limbed particular person chopping up their very own abdomen.

Midjourney’s crude banning of prompts regarding reproductive biology highlights how tough it’s to average content material round generative AI programs. It additionally demonstrates how the tendency for AI programs to sexualize ladies extends all the way in which to their inner organs, says Rockwell.
