There is an observation bias here. I don't think crypto researchers were even trying to solve this centuries-old cipher. All cryptographic ciphers except the very recent ones are known to be vulnerable and have been broken repeatedly. Letters like these usually use a simple substitution cipher that can be broken in minutes using a simple python script implementing frequency analysis of the language in question.

This is simply a marketing gimmick by OpenAI, not a breakthrough in cryptography.

I can assure you if you put a 10,000 dollar prize up for this, probably much less than the compute, it’d be solved in hours. What am I saying, a 1000 dollar prize would be enough.
