Facebook Feed Recommendations AI system

UPDATED JUN 4, 2025

The content you see on your Facebook Feed Recommendations is selected, ranked and delivered to you by an artificial intelligence (AI) system. Within one AI system, multiple machine learning models work together to deliver your experience. These models and their input signals are dynamic and they change frequently as the system learns and improves over time.

Overview of Facebook Feed Recommendations

When you view and interact with Facebook, one of the underlying AI systems delivers suggested content to your Feed on the Facebook Home tab. This is content you may be interested in, including content from Pages or groups you may not follow. Sometimes you’ll also see suggestions for other content like reels, events and live video.

Note: Your Feed might also include connected content and advertisements. That content is not powered by the AI we describe in this system card. Connected content is described in Facebook Feed.

How Facebook Feed Recommendations works

The AI system behind Facebook Feed Recommendations automatically determines which content shows up in your Feed, and in what order, by predicting what you’re most likely to be interested in or engage with. These predictions are based on a variety of factors, including what and whom you’ve followed, liked or engaged with recently. Here’s how it works:

Gather inventory
The system gathers a portion of the public content available on Facebook, which may include photos, videos and links. This does not include content that goes against our Community Standards or that goes against our Recommendation Guidelines.
Leverage signals
Next, the AI system considers a variety of input signals about the content. These signals might include how you’ve engaged with similar content or your interests on Facebook.
Make predictions
From there, the system has models that help it make predictions about public content you’ll find most relevant and valuable.
Rank content
Finally, the system ranks content from the previous step. Content that the system predicts will provide more value for you is shown higher in your Feed. This step helps the system make content recommendations that more closely match your preferences.

How to customize what you see

Your experience on Facebook Feed Recommendations is personalized based on your activity, and you have options to control or customize what you see. Below, we describe how to do this with different in-product features. Options shown here may not be available to everyone.

Discover non-personalized content

To discover reels, videos and other content that is not personalized specifically to you, use the search feature in the Feeds tab. By doing so, your search results will be based on the search term you enter. Learn more.

Hide

You can hide a post. This action also helps to limit similar content from showing up in your Feed.

Interested/Not interested

Clicking “Interested” or “Not interested” on a post will temporarily increase or decrease the ranking score for a post and other posts like it.

Report content

If you see something you think goes against our Community Standards, you can report it to us. You can also report posts that you think are spam or false news.
