Why 96 variations and not 256?
Discussion
Too many variations will become too difficult for people to differentiate. You want a set of memorable characteristics and memorable variations, so when two AIs make the same caricature, you'll recognize them as the same underlying persona
Claude's first take:

45. Skin texture: 4 variations (smooth, average, textured, heavily textured)
46. Neck musculature: 4 variations (minimal, average, defined, highly defined)
47. Facial adiposity: 5 variations (very lean, lean, average, full, very full)
### Calculation of Total Combinations
To calculate the total possible combinations, we multiply the number of variations for each characteristic:
5 × 8 × 5 × 5 × 4 × 4 × 5 × 3 × 5 × 4 × 3 × 4 × 5 × 5 × 3 × 4 × 3 × 3 × 4 × 4 × 3 × 4 × 3 × 4 × 3 × 4 × 3 × 3 × 3 × 3 × 3 × 3 × 6 × 5 × 5 × 7 × 6 × 4 × 8 × 5 × 4 × 4 × 4 × 6 × 4 × 4 × 5
This equals approximately 1.8 × 10^38 possible combinations, which is an extraordinarily large number - far more than the number of humans who have ever lived or will live in the foreseeable future.
What's wild isn't that this is perfect, but that it cost me less than 1¢ and 30 seconds to produce, and it's not a bad start
Yeah, I got something similar, but this is no good. The variations are too subtle. To me: one person can be an animal, another can be a simple square (but that is the only square in the set), another can be a single letter. Big themes like professions, nationality, memorable colors, actions
The Brazilian black rabbit astronaut riding a blue bike would be an awesome image.
It might be better to turn the key into words first and then ask the AI to generate layers for those words.
Don't lose signal by giving it a bag of words, design a system with the desired domain. Otherwise how can you tell the difference between an image of "red green blue" and one of "green blue red"? It's too much work to imagine the underlying words in order to decide whether two potentially radically different avatars are the same. It's easy enough to try both though 🤷🏻♂️
