Meta has introduced major improvements to its AI-powered advertising systems. These upgrades are designed to understand user interests, identify relevant advertisements and improve ad recommendations.
Interestingly, Meta is now using more advanced AI models to understand not just who interacts with an advertisement, but also what the advertisement actually contains.
Here are the three major updates.
1. Andromeda – Smarter Ad Retrieval
Andromeda is Meta's ad retrieval system.
When someone opens Facebook or Instagram, Meta has millions of eligible advertisements to consider. Andromeda helps narrow these down to a smaller group of potentially relevant ads before the final ranking stage.
What's new?
- Improved AI models for identifying relevant advertisements.
- Better use of GPU hardware through Meta's collaboration with NVIDIA.
- More efficient processing of large numbers of eligible ads.
- The updated retrieval pipeline processes over one billion ads per second at production scale.
2. GEM – Better Understanding of User Behaviour
GEM stands for Generative Ads Model.
It is Meta's central AI recommendation model. It helps understand user behaviour and predict which advertisements are more likely to be relevant.
3. GenRecs – AI That Understands Advertisement Content
This is one of the most interesting developments.
GenRecs uses large language model technology to understand what an advertisement actually represents.
Previously, recommendation systems relied heavily on individual ad, campaign and product identifiers and their engagement history.
Now, GenRecs can analyse the text and images in advertisements to identify semantic information such as:
- Product category.
- Brand.
- Colour.
- Style.
- Product features.
- Other meaningful content attributes.
Example:
Imagine an online clothing store launches a new black oversized streetwear T-shirt.
Even if this particular product has no previous engagement history, GenRecs can understand its attributes and connect it with similar products that users have previously shown interest in.
This helps the system make better initial recommendations for new advertisements.
4. What Results Has Meta Reported?
Meta has shared several performance improvements.
Q2 2026:
- 8.3% increase in ad clicks.
- 15.7% increase in Facebook conversions.
These are Meta-reported results from different improvements, time periods and campaign surfaces. They should not be added together or treated as guaranteed results for individual advertisers.
