Both Chat GPT 4o and Claude 3.5 can trivially solve this puzzle if you direct them to do program synthesis to solve it. (that is write a program that solves it - e.g. https://pastebin.com/wDTWYcSx).
Without program synthesis (the way you are doing it), the LLM inevitably fails to change the correct position (bad counting and what not)
and what prompt you gave them to generate program? Did you tell explicitly that they need to fill cornered cells? If yes, it is not what benchmark is about. Benchmark is to ask LLM to figure out what is the pattern.
I entered task to Claude and asked to write py code, and it failed to recognize pattern:
To solve this puzzle, we need to implement a program that follows the pattern observed in the given examples. It appears that the rule is to replace 'O' with 'X' when it's adjacent (horizontally, vertically, or diagonally) to exactly two '@' symbols. Let's write a Python program to solve this:
this is why I will never try anything like this on a remote server I don't control. all my toy experiments are with local llms that I can make sure are the same ones day after day.
