Meta Andromeda: What It Changes for Your Ad Creatives
Meta Andromeda, the system that preselects ads: what Meta has published, what it recommends on creative diversification, and what it has never said.
Contents
Since 2025, “Andromeda” has been used to justify almost anything on Meta: launch 50 creatives a week, delete your ad sets, give up on targeting. Some of that advice is sensible. Some of it credits Meta with numbers it has never published.
This page sticks to what Meta has written: its engineering blog, its Meta for Business pages and its earnings calls, read on October 12, 2026.
What is Meta Andromeda?
Andromeda is Meta’s ads retrieval system. When an ad slot opens up, it selects a few thousand relevant ads out of tens of millions of candidates. Heavier ranking models then pick the ones that get delivered.
Meta introduced it on December 2, 2024 on its engineering blog, and rolled it out in the second half of 2024. The published figures:
| What Meta measured | Reported result |
|---|---|
| Retrieval system recall | +6% |
| Ads quality | +8%, on selected segments |
| Model capacity | 10,000 times larger |
| Hardware | NVIDIA Grace Hopper chips and MTIA, Meta’s in-house accelerator |
In July 2025, Meta announced Andromeda’s extension to Facebook Reels, with nearly 4% more conversions on Facebook mobile Feed and Reels.
What does Meta recommend to advertisers?
The Meta for Business pages that mention Andromeda all hold the same line:
- April 22, 2025. Meta writes that the focus has shifted from niche targeting to creative diversification, which it calls the best lever to find the most relevant audiences.
- March 27, 2025. Meta explains that Andromeda works behind the scenes as businesses upload more and more creatives to support that strategy.
- December 16, 2025. Meta specifies that ads that look or feel alike are treated as variations of the same creative.
Meta also offers a creative diversity indicator that labels ad sets as high, medium or low. It presents it as an estimate still in development.
For Meta, diversity is not measured in file count. Ten variants of the same video, with a different color or overlay text, are still variations of a single creative.
How many creatives should you launch?
Meta has published no number tied to Andromeda.
Meta’s only figure predates the Andromeda announcement. In November 2024, Meta recommended at least 20 diversified ads in Advantage+ shopping campaigns, putting 20 to 30% of the budget toward testing new ads, and launching new ones every week.
The ranges that circulate, such as 10 to 50 creatives per ad set or 5 to 10 new ads per week, come from tools and agencies. They can be useful benchmarks, but they are not Meta’s guidance.
What Meta’s pages do say clearly is that the difference between creatives matters more than their number.
What makes a creative genuinely different?
If ads that look alike get grouped together, the question becomes: what makes two creatives different?
In practice, what changes the nature of a creative:
- the concept: the promise, the problem addressed, the angle;
- the format: talking head, product demo, static, testimonial;
- the person and the setting: who speaks, where, to whom;
- the hook: the first seconds or the first line.
Changing a button color, an overlay text or the order of two shots produces an iteration, not a new creative. Iterations are useful, to optimize a concept that works, but they do not bring the diversity Meta is talking about.
The article on 25 ad creative concepts gives examples of genuinely distinct concepts.
Which numbers are wrongly credited to Andromeda?
| What you read | What Meta actually published |
|---|---|
| ”Andromeda increased ROAS by 22%“ | The 22% is about Advantage+, not Andromeda |
| ”Andromeda processes 10,000 times more ads” | The 10,000 is about model capacity |
| ”You need 10 to 50 creatives per ad set” | No number tied to Andromeda at Meta |
| ”Above 60% similarity, a creative gets dropped” | Meta has published no threshold, only a high, medium or low indicator |
| ”Similar ads share a single ID” | Meta does not describe this mechanism in its pages |
A Meta spokesperson, quoted by Marketing Brew in September 2026, sums up the company’s position: its guidance is deliberately based on outcomes, not on a specific model.
What it changes in how you run an account
If diversification is the lever, the bottleneck moves. The job is no longer finding the right audience, but producing and launching more distinct creatives, every week, without spending your days on it.
Three points become critical:
- Name each file by concept and iteration. Otherwise you cannot tell which concepts drive the results. A Meta Ads naming convention exists for exactly that.
- Launch fast. Loading fifty creatives one by one in Ads Manager takes half a day. The Meta Ads bulk upload guide explains how to do it in one pass.
- Test in a readable structure. How you spread creatives across ad sets decides what you learn: that is what testing structures are about.
Apogee’s bulk upload reads the concept and iteration in each file name, groups the ratios of one creative into a single ad, and launches the batch in the testing structure you pick.
Andromeda does not change the media buyer’s job, it changes how the time is split: less time on targeting, more time producing, naming and launching distinct creatives.
What Andromeda does not solve
More distinct creatives do not save a weak offer. Diversification helps Meta find the right people for each message; it does not make the message better.
It does not replace reading the results either. Launching fifty creatives without being able to tell which concepts win just produces more noise.
Finally, Meta keeps changing its system. In July 2026, it announced it had deployed a first generative model into its ads retrieval system, without naming Andromeda. The diversification principles remain; the technical details will change.
