In case you haven't heard of MidJourney, it is a bot that you can interact with on Discord. Before your eyes glaze over, it's also one of the most remarkable displays of bleeding edge "ai," or what I like to refer to as, "really well-made machine learning tech."
Depending on a very broad limitless amount of keywords, you can generate still images of ultra-realistic CGI, renderings based on the style of other well-known artists, fantasy illustrations, yadda, yadda, the list is virtually endless.
I'd rather not give a full review, there are plenty of people out there that write more better than me. Instead, here are some of the renderings I came up with while playing around.
