I don´t know how anyone should even know if you use AI generated levels. Besides the fact you just told us. I know this whole AI thing is going to be more and more of a topic on here, there are several posts about it already. My opinion -and i guess that is all that anyone can give you- is that you can use as much or as little AI generated stuff as you want. Depending on what kind of AI program you use, of course. Some allow the use of generated stuff at least for non-commercial purpose, others may not. And contrary to popular belief, there are AI programs that are fed with free stuff, free pictures for example. But that is another topic, i guess.
Thing is, even big companies are going to be using AI in the future, i´m pretty sure of it. Why should smaller, or even indie developers, not use it? We would have much more of a reason to. Less people, smaller budget(or non at all, if it´s just a hobby).
