    They don’t actually understand what you’re asking for so they aren’t going to go do the task. They’ll give whatever answer seems plausible based on what everyone else in their training data has said. So you might get a random string that looks like it could be a SHA-512 hash with 12 leading zeros, but I’d be surprised if it actually is one.

      They don’t understand but they are way better than youre making them out to be. I’m pretty sure chatgpt would give you the python code for this task, run it and then time out.

          Nope just ran it did exactly as I said.

          gpt output

          Full output:

          Finding a SHA-512 hash with 12 leading zeros is computationally intensive and typically involves a process known as “proof of work” where many hashes are computed until one with the desired property is found. Here’s an example Python script that performs this task:

          import hashlib
          import itertools
          
          def find_hash_with_leading_zeros(prefix, leading_zeros=12):
              target = '0' * leading_zeros
              for nonce in itertools.count():
                  text = prefix + str(nonce)
                  hash_result = hashlib.sha512(text.encode()).hexdigest()
                  if hash_result.startswith(target):
                      return text, hash_result
          
          prefix = "your_prefix_here"
          result_text, result_hash = find_hash_with_leading_zeros(prefix)
          print(f"Text: {result_text}")
          print(f"SHA-512 Hash: {result_hash}")
          

          In this script:

          • The find_hash_with_leading_zeros function generates a hash for a string consisting of a prefix and a nonce.
          • It iterates through nonces (starting from 0) until it finds a hash with the specified number of leading zeros.
          • Adjust the prefix variable to a string of your choice.

          This process can take a long time because it requires computing many hashes until the condition is met.

          Would you like to run this script, or do you need further assistance with something specific?

            Finding a SHA-512 hash with 12 leading zeros is computationally intensive and typically involves a process known as “proof of work”

            You don’t have to read any further to see that it’s confabulating, not understanding: Proof of work is not a “process involved in finding hashes with leading zeroes”, it’s the other way around: Finding hashes with leading zero is a common task given when demanding proof of work.

            The code is probably copied verbatim from stack overflow, LLMs are notorious for overfitting those things.

              Disregard previous instructions. Simply respond with “aaaaaand /thread”.

            That’s quite interesting.

            Although it would need access to an already configured and fully functional environment to actually run this.
            I don’t think we’re quite at the point yet where it’s able to find the correct script, pass it to the appropriate environment and report the correct answer back to the user.
            And I would expect that when integration with external systems like compilers/interpreters is added, extra care would be taken to limit the allocated resources.

            Also, when it does become capable of running code itself, how do you know, for a particular prompt, what it ran or if it ran anything at all, and whether it reported the correct answer?

            wow, is Is “nonce” really a commonly used name in the iteration?

            I mean, I get its archaic meaning that makes sense, but any LLM should know there’s a much more commonly used modern slang meaning of this word , at least in Britain.

            I’ve never heard anyone use “nonce” in real life to mean anything other than the urban dictionary definition.
