Midjourney is a Discord-based AI art tool that enables users to create unique, AI-generated images for commercial projects using state-of-the-art GPT-3 technology. It is currently in open beta and available to anyone with a Discord account. Note that as with any AI-based tool, it is important to consider potential risks associated with artificial intelligence when using Midjourney. The tool falls under the category of Generative Art, and the pricing model for Midjourney follows a freemium structure.
