X Rolls Out Major AI Update That Allows Grok to Rank Your Following Feed

X has rolled out a major artificial intelligence update that allows Grok, its in-house AI system, to rearrange posts in the Following feed based on user relevance. Instead of displaying posts strictly in the order they were published, Grok now determines which posts appear first by analysing each user’s habits, interests, and engagement patterns. The update went live shortly after Elon Musk encouraged users to refresh their X apps to see the change.

How the New Grok Ranking Works

With this update, a user may now see a close friend’s recent post placed above an earlier update from a celebrity or public figure, even if the celebrity posted first. The system prioritises relevance over time, surfacing content that Grok believes is more meaningful to individual users.

For those who prefer the traditional layout, X still provides access to an unfiltered chronological timeline through the feed settings. This ensures that users who value the original “real-time” experience can still opt out of the AI-ranked view.

The Biggest Change to the Following Feed Since 2022

This marks one of the most significant changes to the Following feed since Elon Musk’s overhaul of the platform began in 2022. Until now, the Following feed has been known as the “unfiltered timeline” where posts appear in exact chronological order. By introducing Grok into this space, X is turning a previously time-based system into a discovery-driven experience, even though the content still comes only from accounts users intentionally follow.

Placing Grok directly inside one of the app’s most visited sections also makes the AI more visible and central to the overall user experience.

Impact on Creators and Content Visibility

The shift from a chronological to an AI-ranked system means creators may begin to experience changes in how their posts appear to followers. Accounts that typically get lost in the middle of a busy timeline could appear higher if Grok detects that a user frequently interacts with their content.

For example, if a user often likes posts from a small business owner but rarely engages with a major public figure, the small business owner’s posts may rise above newer posts from the celebrity. This change could reshape visibility patterns for both well-known and emerging creators.

Behaviour-Driven Feed Personalisation

The update also places more importance on user behaviour. Every like, comment, share, or profile visit becomes a ranking signal, influencing what appears at the top of the Following feed. As users interact more, their feed will adjust more quickly, creating a more personalised browsing experience.

For everyday users, this could make the Following feed feel more relevant and engaging. For creators and businesses, ranking higher may lead to more consistent engagement, especially if their content aligns with patterns that Grok identifies.
