Summary

X announces a major overhaul replacing its recommendation algorithm with Grok AI within 4-6 weeks, processing 100 million daily posts to improve content discovery for new users and small accounts, though impact may be limited as users can bypass the algorithmic feed.

Key Points

  • X shifts its recommendation algorithm to be fully powered by xAI's Grok system within 4-6 weeks, with Grok analyzing over 100 million posts and videos daily to match users with relevant content
  • The AI-powered system aims to solve visibility issues for new users and small accounts by better understanding content and providing users the ability to adjust their feed by asking Grok directly
  • The impact remains uncertain since many X users can set their 'Following' feed as default and bypass the algorithmic 'For You' feed entirely, limiting exposure to the new recommendation improvements
