Musk says X will scrap heuristic as Grok will personalise feed
Elon Musk on Friday said that X will replace its heuristic-based recommendation system with AI-powered Grok within 4–6 weeks. Grok will process over 100 million posts and videos every day to improve content visibility and let users personalise feeds through conversational controls. The system aims to learn directly from user behaviour and content trends rather than relying on manual tuning.
