Is it legal to sell art created by the Midjourney AI?

Yes, it is generally legal to sell art created by the MidJourney AI. The legality of selling art generated by an AI like MidJourney hinges on the terms of service provided by the AI platform and intellectual property laws governing the use of AI-generated content. Typically, if a user has utilized MidJourney or a similar AI to create artwork and the terms of use grant them the rights to the output they generate, they may legally sell that artwork. However, it should be noted that laws and platform policies can vary significantly by jurisdiction and over time, so for a definitive answer, one should consult the relevant legislation and the MidJourney's terms of service at the time of sale. It’s also wise to consider any copyright claims related to source material that might have been used by the AI in creating the art.
