That’s MidJourney! I tried SD too, but the results are a lot less consistent. Also creating variations on MJ is just so much easier, so I went with that.
I agree, I hope someone cracks the prompt code to getting the same results in SD so you can avoid the cost though. I hear it's just that MJ takes the user prompt and adds pre built strings to it which creates the better results & consistency. I have seen people dial in extremely detailed prompts to get very similar results.
