X, formerly ‘Twitter,’ is cooking up one of its largest overhauls ever: a completely AI-run feed which can also be tailored to individualized timelines for each user. Powered by Grok AI, the update is part of an effort to redefine how media is consumed on the platform and represents the latest phase in Elon Musk’s vision for X as a “global town square.”
A Major Twitter Algorithm Update
The Twitter algorithm has long been weighted toward a combination of chronological posts and ranking based on engagement. But the new X personalize algorithm goes a step further by incorporating state-of-the-art AI models alongside user input. The X AI, or so called learning algorithm, powered feed will change on the fly, with every user’s timeline being personalized and flexible.
Musk has suggested that the system will be “purely AI” by November 2025 and receive regular open-source updates. That is to say, users and developers will now have unmatched visibility into algorithm behavior – a unique characteristic of X compared with its competitors.
How Does X’s New A.I. Algorithm Work?
Unlike previous ranking systems, the new model combines implicit signals like whether a user has liked or spent time watching a video with explicit input taken from the users. Through Grok AI on X, users can “prompt” their feeds by telling the algorithm what they want more or less of. For example, a user interested in tech news can request more AI updates, while filtering out unrelated entertainment posts.
This degree of customization reflects a broader trend in personalized social media feeds, where platforms prioritize relevance and control over passive consumption.
X Timeline Changes and User Control
The update introduces a new level of X timeline changes. Instead of being limited to who they follow, users will discover content across the platform based on their expressed interests. This bridges the gap between “social graph” feeds (content from people you follow) and “interest graph” feeds (content based on what you like).
For many, this raises the question:
How different is the new X from Twitter’s old algorithm?
The answer lies in flexibility. While Twitter prioritized engagement signals from accounts you followed, the X personalized timeline can surface posts from any creator if it aligns with your profile.
Pros and Cons of X’s AI-Powered Feed
The benefits are clear: more relevant content, fewer irrelevant posts, and dynamic feed adjustments. For creators, this could mean better visibility if their work resonates with niche interests. For users, it’s a chance to curate a timeline that feels more aligned with personal passions.
But there are downsides. Critics warn of echo chambers, where users only see content that reinforces their views. Others worry that the reliance on explicit instructions may discourage casual users from shaping their feed.
X vs TikTok: Competing Algorithms
Industry observers have compared the X AI feed vs TikTok algorithm, noting similarities in how both platforms emphasize content discovery. However, X’s model gives users more direct input, a move Musk claims will make the platform more transparent and user-driven.
What’s Next for X?
With the Elon Musk X algorithm update, the company is betting big on personalization as the future of social media. By merging AI-driven insights with user control, X hopes to not only improve engagement but also redefine how people experience online conversations.
As the rollout approaches, one thing is clear: the new X features in 2025 are designed to put the user at the center of the feed. Whether this will increase satisfaction or spark new debates over algorithm bias, remains to be seen.
