AI image generators have exploded in popularity. But how exactly do they work? And why are some people raising concerns about their usage?

Generating images with the use of artificial intelligence (AI) is something that has been widely discussed in recent years. Stories range from positive reviews of how impressively capable this new technology is to fears that it marks the beginning of the end for the photography and creative industries.

But how do they work? And what can they be used for? In this article, we take a closer look at the technology to answer these questions and explore how it has already managed to gain a bad reputation in the photography industry. But first – what exactly is an AI image generator?

What is an AI image generator?

An AI image generator, otherwise known as a text-to-image generator, is a piece of software that uses AI to create digital images from scratch using text prompts input by a human user.

AI image generators have many uses, from functional jobs such as redesigning the interior of your apartment, creative projects like producing fine art, or bespoke images for advertising to potentially more sinister uses such as creating deepfakes.

How do AI image generators work?

At the most basic level, a user inputs a number of keywords into a piece of software and a digital image based on those keywords is created.

This may sound simple, but an awful lot of technology would have been used to create and train the software.

Just like a human, a computer cannot create an image of something it has never seen. Therefore, every AI image generator has been trained on millions, if not billions, of digital images to understand what things look like. It then uses this knowledge to make an educated choice about what to draw when prompted by text keywords.

Without such training, AI image generators would not be fit for purpose. For example, if you had never seen what a cat looks like – or h
