Breaking MidJourney with 50MP
2023-09-21

Any mad scientists here? For the past few days I have been running the same prompt over and over in an attempt to break MidJourney – and I finally succeeded… well… kinda. I created a 50 megapixel image (16,320 x 3,072px) and then MidJourney said, “Nah man, you done!” 🤣

The new pan feature is really amazing, but I was curious about its limits (and learned some things in the process). I came up with a prompt to give some cool psychedelic sci-fi output, then added “–ar 1:8” in order to make a really tall canvas. Then I simply kept panning to the right and changing colors in my prompt, nothing else. The cool thing about panning is that it keeps your resolution, but adds more with the new generation. If you zoom out or anything, it downsizes the image again, so you have to only use pan.

Anyway, after a bunch of pans the grid images stopped displaying. Maybe a size limit on Discord or something, but instead of an image I was given a URL link – that didn’t work either, lol. So to even see the images I would upscale all four, then they showed. Finally, after 3 days of prompting, I hit the wall. After reaching over 16 thousand pixels it fails every single time. I’m sure the devs are aware of a file or pixel limit on their site or Discord or something, but I got it. I also found that if I compare an image early in the process to late, the early one actually has more detail in shadows, whereas the later images are underexposed. This shouldn’t happen, but I’m thinking it is from saving an image over and over again, losing quality in the process. Interesting. So technically I could composite the old with the new and get a  great image. Okay, I’ll shut up now. Back to my mad scientist AI experiments!
