Hey Oliver, I had noticed the same things. Images seem to be far lower quality at the moment using the API than I have had previously. As you did, I have also done some tests against the Bing image creator - and, while I appreciate it might include some newer capabilities - the results are drastically different through all of my tests. It is rather strange. I feel better knowing someone else might be seeing the same thing so it’s not only in my head
