According to Musk at X, X's recommendation system will "evolve rapidly," with the goal of removing all hard-coded heuristics within the next four to six weeks and replacing it with a fully-powered, in-house AI model, Grok. Musk stated that Grok will "read posts and watch videos individually," processing over 100 million pieces of content daily to match users with topics they are most likely to be interested in. Users will also be able to temporarily or permanently adjust their timeline preferences through conversations with Grok. Media reports on the original post also pointed to the same key points: fully AI-powered recommendations, conversational personalization, and increased visibility for new users and small accounts.
Currently, these adjustments are in the announcement phase, with the timeline being a goal rather than a fait accompli. The specific rollout schedule and actual effectiveness remain uncertain. Discussions are centered on two key areas: first, will the complete removal of heuristics exacerbate the model's amplification of "clickbait" and "emotional appeal" content? Second, will hyper-personalization create the "information cocoon" that exists in the user experience? These issues await mitigation through subsequent product design and transparency mechanisms.
Frequently Asked Questions
Q: Who announced this change and when will it be released?
A: Musk posted an explanation on X on October 17, 2025, which was subsequently quoted and sorted out by many media outlets.
Q: Has the 4–6-week deletion of all heuristics been confirmed to be implemented?
A: This is the target timeline, and full launch has not yet been confirmed; there is uncertainty about the scope and pace of subsequent implementation.
Q: What exactly will Grok do?
A: According to Musk, Grok will process more than 100 million posts and videos every day, and make recommendations based on real-time data and user behavior, replacing fixed rules set by humans.
Q: What impact does it have on ordinary creators?
A: The official statement is that it will alleviate the problem of "good content not being visible to anyone" for new users or small accounts, but the actual degree of improvement needs to be observed through data and cases after the launch.
Q: How can I adjust the flow of information?
A: We plan to add the ability to make direct requests to Grok to enable conversational parameter adjustments, allowing for temporary or permanent modification of preferences; details and permissions have not yet been announced.
