What is AI image generator Midjourney? The deepfake technology delighting and tricking the internet

Fake images of Pope Francis and Donald Trump created through Midjourney's AI technology went viral

News agencies warned consumers Tuesday to be wary of deepfake mugshots of former President Trump flooding the internet in advance of his arrival in court. But what do we know about the platform that's being used to create these realistic simulations?

Midjourney is an AI image program which creates realistic images based on text commands given by users. The company also released a "describe" feature this week which lets users transform images into words.

The company was started in 2022 and operates out of San Francisco, California with just eleven staff members, according to their website.

CEO David Holz recently told The Verge they were stopping free trials after getting an influx of users who made throwaway accounts to access them. The lowest cost plan is now $10 a month.

The Midjourney V5 model is the newest and most advanced model released on March 15th, the company says.

"This model has very high Coherency, excels at interpreting natural language prompts, is higher resolution, and supports advanced features like repeating patterns," the website describes. 

Many dream-like artistic images created by users are shown in the user gallery. Social media users have had fun creating everything from "historical selfies" to World Cup photos shot by famous film directors.

But capability to create simulated images of real people on the platform has caused some controversy and concerns about the technology being used for nefarious purposes.
