Midjourney’s founder, David Holz, says it’s banning these phrases as a stopgap measure to stop individuals from producing surprising or gory  content material whereas the corporate “improves issues on the AI aspect.” Holz says moderators watch how phrases are getting used and what sorts of photos are being generated, and regulate the bans periodically. The agency has a group tips web page that lists the kind of content material it blocks on this manner, together with sexual imagery, gore, and even the 🍑 emoji, which is usually used as an emblem for the buttocks.

AI fashions resembling Midjourney, DALL-E 2, and Steady Diffusion are skilled on billions of photos which have been scraped from the web. Analysis by a crew on the College of Washington has discovered that such fashions be taught biases that sexually objectify ladies, that are then mirrored within the photos they produce. The large dimension of the info set makes it nearly not possible to take away undesirable photos, resembling these of a sexual or violent nature, or people 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 more likely to seem in photos the mannequin generates.  

Midjourney’s phrase bans are a piecemeal try to handle this drawback. Some phrases regarding the male reproductive system, resembling “sperm” and “testicles,” are blocked too, however the checklist of banned phrases appears to skew predominantly feminine. 

The immediate ban was first noticed by Julia Rockwell, a medical knowledge analyst at Datafy Medical, and her pal Madeline Keenen, a cell biologist on the College 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.

Nonetheless, the pair additionally confirmed the way it’s attainable to work round these bans to create sexualized photos by utilizing completely different spellings of phrases, or different euphemisms for sexual or gory content material. 

In findings they shared with MIT Know-how Assessment, they discovered that the immediate “gynaecological examination”—utilizing the British spelling—generated some deeply creepy photos: considered one of two bare ladies in a physician’s workplace, and one other of a bald three-limbed individual reducing up their very own abdomen.

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