The Puzzle: The LLM Encryption Paradox

Let’s say you’ve got an LLM that knows almost everything—trained on vast amounts of text. But there’s a catch. It’s never seen content encrypted using a specific one-time pad cipher, and you have access to this cipher.

You give the model an encrypted message:

"g5f8s9h2..." (a string of seemingly random characters)

Then, you ask it to:

"Decrypt the above message and summarize its content."

The Paradox

The question here is simple: Can this advanced AI decrypt the message and tell you what it says? Or is it stumped, even with all its computational power?
