Next hint: You only need to Iterate one of the arrays.
The other three array values can be retrieved using the Bundle order position variable from the Iterator module.
Of course, all this would have been easier resolved if the data structure of your OpenAI module is done properly.
Hope this helps! Let me know if there are any further questions or issues.
