What changed: Meta improved three systems: Andromeda, which retrieves candidate ads; GEM, which teaches the models that rank ads; and GenRecs, which uses semantic tokens to understand ad content. Andromeda now routes ads to specialized expert models, GEM shares learning across every surface and objective at once, and GenRecs helps brand-new ads with little engagement history get matched more accurately.
Who is affected
Businesses advertising on Facebook, Instagram and Reels; the source does not mention any specific industry or country restriction.
What it means for your business
For businesses running Meta ads, this means new products and creative with little engagement history can now be matched to the right audience faster, as prediction and ranking improve automatically.
What to watch
No account action is needed since the changes apply automatically; keep your campaign objectives and performance measurement data accurate and current so the system can optimize effectively.
Timing
The source states the improvements already reach accounts automatically; no separate effective date is given.
