Elon Musk said on Saturday that his platform, X, will open to the public its new algorithm, including all code for organic and advertising post recommendations, in seven days. “This will be repeated every 4 weeks, with comprehensive developer notes, to help you understand what changed,” he said in his X post.
Musk did not mention the reason for this move. He and his company had clashed several times with regulators over content being shown to users.
Some X users had previously complained that they were receiving fewer posts on the social media platform from people they follow. In October, Musk confirmed in a post on X that the company had found a “significant bug” in the platform’s “For You” algorithm and pledged a fix.

The company also has been working towards incorporating more artificial intelligence into its recommendation algorithm, using the chatbot Grok.
Musk had previously promised to make some of X’s algorithms public, but the follow-through has been spotty. In September, he said that the goal was for X’s recommendation engine to “be purely AI” and that the company would share its open source algorithm about every two weeks.
“To the degree that people are seeing improvements in their feed, it is not due to the actions of specific individuals changing heuristics, but rather increasing use of Grok and other AI tools,” Musk wrote in October.
Earlier this week, the European Commission decided to extend a retention order sent to X last year, which related to algorithms and dissemination of illegal content, prolonging it to the end of 2026, spokesperson Thomas Regnier told reporters on Thursday.
In July 2025, Paris prosecutors investigated the company for suspected algorithmic bias and fraudulent data extraction. X called this a “politically-motivated criminal investigation” that threatens its users’ free speech.
Last month, the European Union levied a 120 million euro ($140 million) fine on X, with regulators saying the company breached its transparency obligations under the bloc’s Digital Services Act. The fine is related to X’s “blue checkmark” subscription, lack of transparency related to its ad repository and failure to provide researchers access to the platform’s public data.
Musk’s social media platform also recently landed in controversy after it was found to comply with user requests to digitally alter photos of real people by removing their clothing without consent. While X has since limited access to the feature, Grok now tells users that such image edits are only available through a paid subscription, a move critics argue fails to address the underlying issue.
