Nowadays, with generative Artificial Intelligence, it is possible to create photo-quality images based on prompts. A prompt is the command given to an AI system to generate the image, for example:
"A dog and a cat traveling together in a spaceship to Mars, illustrated in a comic style."
A prompt typically consists of a descriptive content and a set of instructions, such as specifying whether a photo-quality image should be produced, or if it should be in an art-deco or comic book style.
Most AI image systems are accessible online, in the cloud, such as DALL-E 2 (developed by OpenAI, the same company that created ChatGPT). Due to the high server costs associated with generating images in this manner, it is not surprising that most of these services eventually become paid.
However, it is also possible to create images on your own Apple computer.
Stable diffusion is a model that can generate photo-quality images based on text prompts.
Stable diffusion can be run locally on a recent Apple computer using the DiffusionBee app (download DiffusionBee here). The time it takes to generate an image largely depends on the power of your computer, especially the graphics card. Expect around 10-30 seconds per image on a robust Mac M1.
