With no drama. I'm not sure the bot answer is correct, but looks correct.
Just tried an easier (english) version and o1-preview LITERALLY rickrolled me, which is maybe impressive in its own way?
UPDATE: Claude crushed it however.

Can you decrypt the following? I don't know the cypher.
mzilj ivdrzej ufidrek ze kyv sfup reu tre ivrtkzmrkv crkvi ze czwv
Certainly! The encrypted text is:
``` mzilj ivdrzej ufidrek ze kyv sfup reu tre ivrtkzmrkv crkvi ze czwv ```
When we decrypt it, we get:
``` never gonna give you up let you down and desert you ```
It appears to be a line from Rick Astley's song "Never Gonna Give You Up."
> Without knowing the cipher used to encrypt this message, it’s hard to decrypt it directly. However, the structure and letter patterns suggest it might be a simple substitution cipher, possibly Caesar or some variation of it.
> Let me attempt a few common methods to see if I can identify the cipher.
> The most frequent letters in the encrypted message are 'r', 'z', 'v', and 'e'. In English, the most common letters are typically 'E', 'T', 'A', and 'O'. This suggests the cipher could be a simple substitution or a Caesar cipher.
> I'll now attempt to apply a Caesar cipher decryption by shifting the alphabet through all possible rotations to see if we get readable text.
> One of the decrypted messages, with a shift of 17, reads:
> *"virus remains dormant in the body and can reactivate later in life"*
> It seems like the correct decryption, revealing information about a virus that can remain dormant in the body.
