Asking Chat GPT-4 to Solve the Z32

Just was curious as chat GPT 4 was available I wanted to ask it to solve the Z32 from the Zodiac Killer but it was unable to do so at this time. Perhaps with the arrival of GPT 5? We’ll see!

My question: Are you able to decipher the Z32 from the Zodiac Killer?

Response: As an AI language model, I don’t have the ability to conduct investigations or decipher previously unsolved codes independently. The Z32 is a 32-character cipher sent by the Zodiac Killer, who was responsible for a series of murders in Northern California during the 1960s and 1970s. Despite numerous attempts by both amateur and professional codebreakers, the Z32 cipher remains unsolved to this day.

In 2020, a team of amateur codebreakers announced that they had successfully deciphered the 340-character cipher (Z340) from the Zodiac Killer, which had remained unsolved for more than 50 years. However, the Z32 cipher still lacks a confirmed solution.

My training data only goes up until September 2021, so I am not aware of any new developments or breakthroughs in the case.
