Combinatorial Explosion
2023-02-05

The other day someone asked if it were possible for two people to settle on the same prompt and then get the same end result. Technically the answer is yes, because numbers always have a limit, however, the probability here is insanely rare. It’s kind of a trippy thing to think about. So get this…

When you enter a prompt it is assigned a random seed, and the seed creates the random noise from which the image generates from. A seed can be from 0 to 4,294,967,295. So let’s round and say chances are 1 in 4,294,967,296 since 0 is an option – but that’s not it. One generation gives you 4 images, so technically now the chances are 4 times that now. But wait, what about parameters? If Stylize is from 0 to 1000 in V4, that is now 1000 more options per seed, per grid. Then add Chaos into the mix and we have 0 to 100 more options per seed, per stylize. Now if you multiply all of the options together we are looking at something like 1 in 174,000,000,000,000,000. I didn’t know this but that number is 174 quintillion.

The problem is that we are not even done yet. We could use 4a or 4b, V2 or V3, and even toss in aspect ratios. The combinational explosion is too large for me to even contemplate. So basically the amount of variation and randomness is so freakin’ high that it would be amazing if two people not only landed on the same exact prompt, but also got the same final image… I’m not going to do that math, so let’s call this chat done.

InPainting, aka Vary Region

When I am wrong I admit to it, and guess what - I was wrong. The royal we have been wanting and begging MidJourney to add inpainting for what feels like eons. As many of you know, I am a HUGE advocate and word-spreader for MidJourney BUT what I also did is constantly...

One Year Later

I just saw this pop up in my memories and it gave me a good feeling. A year ago today I released the first version of Prompter (the prompt-building spreadsheet) for free just to see if people would use it... I never thought that a year later it would get so much...

Corgi Van Gogh

We were out shopping and my girl saw some wall art of a corgi with a Van Gogh look. She wanted it, but I said “Wait, let’s just use MidJourney and Photoshop to make one that looks like Willow instead!” (our little fluffy tri-color corgi pup). I rolled a few simple...

Hey, been a bit quiet lately. I’m busy working on an animation project using MidJourney and After Effects, a music video for an incredibly talented electronic musician in Colorado, Souliseum... I am currently in the process of moving 1,000 miles away, so it’ll likely...
