X is taking fast steps to execute a radical revolution in the core of its technological operations, as it intends to begin the full integration of its artificial intelligence chatbot, Grok, into the primary algorithm responsible for recommending content to users starting next week. This strategic and technical shift was described by the company’s head of products as the most important and impactful change in the platform’s history, as it will completely alter the contours of the user experience.
In this context, Nikita Bier, head of products at X, stated in a post on the platform on Thursday: “The full power of Grok AI will be unleashed and applied to the algorithm next week. This will be the most important change we have ever made at X.” According to technical reports, this comprehensive update bears the codename “Phoenix,” is built entirely on advanced transformer architecture, and relies on an end-to-end deep learning approach. The company also plans to transparently release the source code for this update on GitHub for developers on the same day it goes live for general users.
This bold shift represents an official and final departure from traditional ranking signals based on direct engagement, such as likes, reposts, and follows. For decades, these metrics governed and determined the quality of what users saw on the platform. Instead, the platform is moving toward an advanced system based entirely on intelligent content analysis powered by artificial intelligence, meaning the system will attempt to understand the deep context of each post rather than merely counting clicks on it.
A long road toward AI-powered news feeds
This complex technological integration is not a spur-of-the-moment step, but rather the culmination of more than a full year of gradual and deliberate changes within a comprehensive vision to develop the platform. In October 2025, billionaire Elon Musk transparently announced that X would abandon all traditional heuristic methods from its algorithm within a few weeks. He explained at the time that Grok’s role would crystallize into literally reading every post and watching every video published on the platform, with the aim of achieving optimal alignment between users and the content they prefer with extreme precision.
In a subsequent step in January 2026, X made significant parts of its recommendation system open-source, with publicly released documents clearly indicating that the new system relies entirely on a transformer based on Grok AI to learn relevance and importance by monitoring continuous user interaction and analyzing their content consumption behavior.
Nikita Bier has played a pivotal role in these changes. He is a serial entrepreneur with extensive experience in building digital communities, and his previous applications were previously acquired by tech giants like Meta and Discord. Since joining X as head of products in mid-2025, Bier has highlighted 2026 as the “year of the creator,” claiming that the platform has already doubled financial payments and rewards dedicated to content creators in an unprecedented manner to attract more creativity to the platform.
Regulatory and legal challenges on the horizon
This massive algorithm update coincides with a noticeable increase in regulatory and legal scrutiny by European authorities closely monitoring artificial intelligence developments. In February 2025, public prosecutors in France launched an official investigation against X regarding allegations of algorithmic bias, following a complaint filed by a lawmaker stating that the platform’s algorithms may have distorted automated data processing operations. For its part, X described the investigation as politically motivated and flatly refused to cooperate with French authorities’ requests to access its recommendation algorithm. Events escalated in February 2026, when French authorities, in cooperation with the European Union Agency for Law Enforcement Cooperation (Europol), raided X’s offices in Paris as part of this ongoing investigation.
On a separate and parallel front, the European Commission launched a formal investigation in January 2026 under the strict Digital Services Act to evaluate whether X properly and responsibly assessed the risks associated with deploying the Grok tool in European Union countries. This assessment includes serious concerns regarding the dissemination of illegal content, such as AI-generated non-consensual sexually explicit images. The commission also issued a strict order obligating X to retain all internal documents related to the development and training of Grok until the end of 2026 to ensure the transparency of the investigations.
Ultimately, the fundamental question remains: Will this advanced, AI-powered system genuinely improve the user experience and attract more positive interactions, or will it increase regulatory and legal friction with Western governments? The answer to this question may depend heavily on a key variable that X has not yet disclosed: how many of the monthly active users, which the platform claims number 600 million, actually rely on the algorithmic news feed called “For You” for their daily browsing?
Frequently Asked Questions
When will the new AI update for X’s algorithm launch?
The full integration of Grok into X’s core algorithm is scheduled to launch starting next week, coinciding with the publication of the update’s source code on GitHub.
What is the actual role of Grok AI in displaying content to users?
The bot will read every post and watch every video published, accurately analyzing the context instead of relying solely on likes and shares, providing a customized experience for each user.
What legal challenges is the platform currently facing?
X is facing ongoing investigations in France over algorithmic bias allegations that included a raid on its offices, in addition to an investigation by the European Commission to assess the risks of deploying AI technologies regarding illicit content.
