Meta Andromeda Now Scores Every Ad: Fix Your Creative Mix
Meta rebuilt its Andromeda ad retrieval system to score every eligible ad at over one billion a second. Here is how many creatives Indian advertisers now need, with our maths.
One billion ads a second. That is how fast Meta says its rebuilt Andromeda ad retrieval system now scores eligible ads, a 100x jump on the 2024 version. The practical upshot for Indian advertisers: every ad you upload now gets a real shot at the short list, so creative variety matters more than audience tricks.
Meta explained the change in an Engineering at Meta post on 28 October 2026. Trade coverage picked it up on 2 November. Here is what moved, and what we would change in your account this week.
What did Meta change in Andromeda in October 2026?
Meta rebuilt Andromeda, the first stage of its ad delivery, so it now scores every eligible ad and surfaces the best candidates at over one billion ads per second. Meta says Andromeda has delivered a 2.4% increase in conversions on Facebook since 2025. No Instagram figure was published.
Andromeda does not pick the ad a user sees. It cuts millions of candidates to a short list in milliseconds, and a separate ranking model then chooses the winner. If your ad misses the short list, its bid never matters.
The twelve engineers behind the post, including Haiyu Lu and Chonglin Sun, credit a new mixture-of-experts model and GPU code built with Nvidia. Their stated reason is volume: generative AI tools have helped advertisers create “hundreds of millions of new ads”, and the old pipeline could not keep up.

Andromeda 2024 vs 2026: we compared the two Meta posts
Meta first described Andromeda in December 2024. Reading both posts side by side shows where the system grew.
| What | Andromeda 2024 | Andromeda 2026 |
|---|---|---|
| Speed | Tens of millions of ads per second per GPU | Over one billion ads per second |
| Coverage | Tens of millions of candidates cut to a few thousand | Scores every eligible ad |
| Headline result | +6% recall, +8% ads quality on selected segments | +2.4% conversions on Facebook since 2025 |
| Model | Single user tower | Ensemble of specialised user towers with mixture-of-experts gating |
The pattern is clear. In 2024 Meta was making room for Advantage+ automation. In 2026 it is making room for the flood of AI-made creative.
Does Meta Andromeda change how you should build ad sets?
Yes, mostly by making narrow audience splits less useful. When retrieval can score every ad against every user, the creative itself does the targeting. Fewer, broader ad sets with more distinct creatives give Andromeda more to match, and stop your own ads from competing in a dozen tiny audiences.
Media buyers argued this well before the rebuild. Andrew Foxwell, co-founder of Foxwell Digital, is quoted by Net Influencer saying audience containers are “less useful and less necessary than they used to be”. Ignacio Manchi of Ready Set, speaking at a Motion summit in June, put it more bluntly: miss Andromeda’s short list and “you’re not in the game”.
Your creative is now your targeting. Ten copies of one idea is still one idea.
How many creatives does an Indian advertiser need now?
For most Indian SMBs, about five genuinely different creatives a week is a sensible target, up from the two or three many test today. Motion’s 2026 benchmark shows small accounts find a winner roughly every two months at current volumes. Doubling distinct concepts roughly halves that wait.
Our maths. Motion’s Creative Benchmarks 2026 studied 578,750 Meta creatives and $1.29 billion of spend from September 2025 to January 2026. A “winner” earned at least 10x the account’s median spend and at least $500. At ₹94.67 to the dollar (2 November 2026 close), that floor is about ₹47,300.
Motion’s Micro tier is under $10,000 a month, or roughly ₹9.5 lakh. That covers most Indian D2C brands and local businesses.
| Monthly Meta spend | Creatives tested per week | Hit rate | Winners per month (our calc) |
|---|---|---|---|
| Under ₹9.5 lakh (Micro) | 2.8 | 4.0% | 0.49 |
| Micro, raised to 5 a week | 5 | 4.0% | 0.87 |
| ₹9.5 lakh to ₹47 lakh (Small) | 4.1 | 6.4% | 1.14 |
| ₹47 lakh to ₹1.9 crore (Medium) | 6.6 | 8.1% | 2.31 |
We multiplied weekly volume by 4.33 weeks and by the hit rate. At 2.8 a week, a Micro account waits about two months per winner. At five a week, about five weeks. That assumes the hit rate holds, which it only will if the new ads are actually different.
What counts as different in India? A Hinglish founder-to-camera video and a Tamil UGC unboxing are two concepts. The same carousel in three colours is one. Wedding-season gifting, Tier 2 price anchoring and a UPI cashback offer are separate angles worth separate ads.
Pro tip: Label each new ad in your naming convention by concept (hook, format, language), not by date. After four weeks you will see which concepts win, not which versions.
Is the 2.4% Andromeda lift worth chasing?
Not as a number to plan around. The 2.4% is a Facebook-wide average from Meta’s own engineering team, with no Instagram figure and no breakdown by country, vertical or spend. Treat it as a direction, not a forecast for your account.
For scale: a brand spending ₹1 lakh a month at a ₹400 cost per purchase gets 250 sales. A 2.4% lift adds six, taking effective CPA to about ₹391. Useful, not life-changing. The bigger gain comes from feeding the system better inputs.
There are honest objections. Motion’s data skews to US e-commerce and does not track ROAS or revenue, only spend. More creatives also means thinner budgets per ad, and a ₹50,000 monthly account cannot fund five fair tests a week. And “more creative” invites lazy AI variants that Andromeda may simply treat as near-duplicates.
Watch out: Meta’s updated Commercial Terms and Self-Serve Ad Terms take effect on 20 November 2026. They make advertisers responsible for AI-generated content in their ads, including Advantage+ output. Review any auto-generated variants before then.
PingTalks verdict
Raise distinct creative concepts to around five a week if you spend over ₹2 lakh a month on Meta, and consolidate to two or three broad ad sets. Skip bulk AI resizes and colour swaps. If you spend under ₹50,000 a month, ignore volume targets and ship two strong, very different concepts a fortnight instead.
What to do now
- Merge interest-stacked ad sets into two or three broad ones this week. Our Meta Ads guide covers the Advantage+ setup.
- Audit the last 30 days: count truly distinct concepts, not ad IDs. Under eight a month at ₹2 lakh-plus spend means you are starving retrieval.
- Build one regional-language and one Hinglish concept for the wedding season.
- Check AI-generated variants before 20 November, and recheck product browsing settings while you are in Ads Manager.
- Track every Meta change in our Meta Ads updates log, and see the terms delay in last week’s roundup.
Frequently asked questions
What is Meta Andromeda?
Meta Andromeda is the first stage of Meta’s ad delivery system. It narrows millions of eligible ads to a short list in milliseconds, and a separate ranking model then picks the ad a person sees.
What changed in Meta Andromeda in 2026?
In a 28 October 2026 engineering post, Meta said Andromeda now scores every eligible ad at over one billion ads per second, 100 times the 2024 system. It uses a mixture-of-experts model and GPU code built with Nvidia.
Do I need to change anything in Ads Manager because of Andromeda?
There is no new setting to switch on. The gains come automatically, but accounts with broader ad sets and more distinct creatives give the system more to match, so consolidating ad sets and varying concepts is the practical response.
Does the 2.4% conversion lift apply to Instagram ads?
Meta only published the 2.4% conversion increase for Facebook, measured since 2025. It gave no Instagram figure and no breakdown by country or industry, so Indian advertisers should not budget around that number.
How many Meta ad creatives should a small Indian brand test each week?
Brands spending over ₹2 lakh a month can aim for about five genuinely different concepts a week. Accounts under ₹50,000 a month are better off with two strong, very different concepts every fortnight so each gets enough spend.
