What Andromeda Actually Is
Meta rolled out Andromeda in late 2024 as a new ads retrieval engine. It runs on the NVIDIA Grace Hopper Superchip and replaces a lot of the old rule-based delivery with deep neural networks.
In plain terms, it sifts through billions of creatives and signals to decide who sees what. The matching got a lot smarter, and that quietly moved the center of gravity in your account.
The targeting layer you used to obsess over now matters less. The creative you upload matters more, because that is what the engine actually reads to figure out who should see it.
