Facebook Feed Ranked Comments AI system

UPDATED MAR 12, 2025
The content you see on your Facebook Feed Ranked Comments 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 Ranked Comments

When you view and interact with Facebook, one of the underlying AI systems shows you comments on posts in your Feed that are ranked in order of relevance to you. For example, you might see comments on a post from a Page you follow or a group you’ve joined.
How Facebook Feed Ranked Comments works
The AI system behind Facebook Feed Ranked Comments automatically determines which comments on posts you'll see first by predicting what you’re most likely to be interested in. These predictions are based on a variety of factors, including the general relevance and popularity of the comments, as well as your recent activities on Facebook. Here’s how it works:
  1. Display most important comments first
    The system shows comments that may be most important to you at the top of each comment thread. These might include your own comments, your friends’ comments or the author’s comments.
  2. Score and order comments
    Next, the system calculates a score for other comments on a post based on multiple input signals, including the relevance of the comment to the post and how popular the comment is among all viewers. Comments are then ordered by their scores.
  3. Apply filters
    Finally, the system applies filters to remove any comments that may go against our Community Standards.
