Facebook Individual Group Feed AI system

UPDATED JUN 17, 2024
The content you see on your Facebook Individual Group Feed 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 Individual Group Feed

When you visit a group and view and interact with the Individual Group Feed, one of the underlying AI systems delivers status updates, photos, videos and other content that has been posted to that specific group.
How Facebook Individual Group Feed works
The AI system behind Facebook Individual Group Feed automatically determines the order in which posts show up in your Individual Group Feed, 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:
  1. Determine group eligibility
    First, the system checks if the group is eligible for ranking of posts. In order to be eligible, a group needs to meet certain integrity criteria and must have had at least 20 posts in the past day to provide enough content for ranking.
  2. Gather posts
    Next, the system collects all recent posts available for ranking in that group.
  3. Score posts
    The system then calculates a score for each post for a variety of factors, such as the type of post, similarity to other posts and how well the post matches what you tend to interact with.
  4. Apply additional rules
    Then, integrity processes are applied to all posts. These determine which integrity measures, if any, need to be applied to the posts selected for ranking.
  5. Rank posts by score
    Finally, the system puts all relevant posts in order by score. It also accounts for how you tend to interact with Individual Group Feed, for example, if you click to like posts or comment on them. This process determines the order of the posts you’ll see in Individual Group Feed.
How to customize what you see
Your experience on Facebook Individual Group Feed 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.
Manage sorting order
You can sort posts in an order recommended by the AI system (Most relevant) or in a time-based order (Newest activity/New posts).
Manage default sorting order for a group (group admin only)
The group’s admin has the option to set a default sorting order for posts in groups they manage, so that all group members and visitors will see that order as the default.
See newest posts first
Within a group that you are a member of, sorting by "Newest activity" or "New posts" will present all posts in the group in reverse chronological order. Learn more.
How the AI delivers content to you
We want you to see content you enjoy and find interesting. To achieve this, the AI system has models that help it make predictions about content you’ll find most relevant and valuable. These prediction models use underlying input signals to help select content you’re most likely to engage with.
Below are some of the significant predictions—and input signals that inform them—that we use in this AI system.
