X has implemented two key algorithmic changes to its 'For You' feed, aiming to maximize user dwell time. The new ranking model better predicts probable time spent, while the retrieval model prioritizes posts users are likely to read completely. This shift restructures how content from non-followed accounts is filtered and coincides with a significant growth in daily active seconds to approximately 500 billion.
