How to compare 2 photos to check whether the second photo is cleaner than the first photo

I would like to use the OpenAI API to compare 2 photos (one taken before the cleaning of an equipment and second photo which is taken after the cleaning activity is completed) to check whether the second photo is cleaner than the first photo. I prefer to have a score in % of cleanliness.

Hi @jobvtholath ! You’ve asked this identical question in this thread: Comparing 2 images for analysis

Sorry, that was through my mobile / with apple login, due to which I didn’t see the same in ‘my posts’.
