Short answer

Meta Andromeda is Meta's AI ad-retrieval engine, introduced in December 2024, that narrows millions of candidate ads to a shortlist for each person before final ranking. Because it matches ads to people largely through creative signals, it rewards advertisers who supply diverse creative concepts rather than many near-identical variations of the same ad.
