Musk’s X to open source new algorithm in seven days

Elon Musk said on Saturday that social media platform X ​will open its new algorithm, including all code for organic and advertising post recommendations, to the public 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.
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 social media platform for suspected algorithmic bias and fraudulent data extraction, which Musk’s X called a “politically-motivated criminal investigation” that threatens its users’ free ‌speech.
