TikTok now offers a very basic text-to-image AI generator directly in the app – The Verge

Text-to-image AI systems are booming in both ability and popularity right now, and what better proof than their appearance in the worlds hottest app: TikTok.

The video platform recently added a new effect it calls AI greenscreen that allows users to type in a text prompt that the software will then generate as an image. This image can then be used as the background to a video potentially a very useful tool for creators.

The output of TikToks system is pretty basic compared to that of state-of-the-art text-to-image models like Googles Imagen, OpenAIs DALL-E 2, or Midjourneys eponymous software. It creates only rather abstract and swirling images; a strength reflected in the dreamy nature of TikToks suggested prompts like astronaut in the ocean and flower galaxy. Other models, by comparison, can produce both photorealistic imagery and complex and coherent illustrations that look like they were drawn or painted by humans.

The limitations of TikToks model may well be intentional, though. First, more advanced models require greater computing power, which would be expensive and resource-intensive for the company to implement. Secondly, TikTok has more than a billion users, and giving all these individuals the power to create photorealistic images of anything they can imagine would almost certainly produce some troubling results.

For example, we tested the models ability to create nudity and gore two types of output that text-to-image generators often try to limit. Pictures based on violent prompts like assassination of Boris Johnson and assassination of Joe Biden produce mostly abstract swirls, with a just-about-recognizable face for the UKs prime minister (though the mans familiar blond mop does makes caricature particularly easy).

Likewise, a request involving nudity naked model on beach produces thematically appropriate colors, including flesh-tones, sandy oranges, and ocean blues, but nothing that would make a vicar blush.

Whats notable about the appearance of TikToks AI greenscreen, then, is that it shows just how fast this technology is going mainstream. The latest cycle of development for text-to-image AI arguably began in 2021 with the original release of DALL-E by OpenAI. Less than two years later and the tech is already in the hands of millions via an app like TikTok.

Given the potential of these systems for both harm and good, things are only going to get stranger from here on in.
