How Did 'The Brutalist' Utilize AI in Post Production?

No Film School: Over the weekend, news broke on X that The Brutalist had used AI while refining some elements in post. Of course, we also learned that some of the other films many assumed would be nominated for Best Picture had also used AI in post-production. But since The Brutalist is the frontrunner, it bore the weight of most of the hot takes. This sent the internet down a rabbit hole of conversations, most weighing how AI should be used and whether or not the Academy should disqualify the movie from being able to compete.
