Meta Ads Deep Analysis

Andromeda + GEM + Lattice (2026)

Meta's delivery stack was rebuilt across three releases:

Andromeda (Oct 2025) — ad-retrieval ranking model with 10,000× more
model capacity than the previous funnel (Meta Engineering, Dec 2024).
Filters the candidate creative set before the auction layer ever sees it.

GEM (Generative Embedding Model, late 2025) — replaces the feature
pipeline. Creative content embeds directly into the targeting space, which
is why "creative is the new targeting" is now mechanical truth not slogan.

Lattice (rolled out late 2025 / early 2026) — sequence-aware optimizer
on top of GEM that uses user-action sequences to rank candidate ads.
