Craiyon is an AI model that generates images from text. The user (that's you) enters a text prompt (what you want to see) and Craiyon then goes about creating it. It was developed as a lighter version of OpenAI's DALL-E, and was initially named DALL-E Mini.

According to the Craiyon website, they were asked to change the name away from DALL-E Mini by OpenAI to avoid confusion with their DALL-E model.

Using Craiyon is no more difficult than using DALL-E Mini. You can access it on the Craiyon website.
