Musk Says X Will Open-Source New Recommendation Algorithm, Including Ad Code, in Seven Days

The move answers regulatory scrutiny over X’s recommendations following Grok-related content failures.

Overview

  • Musk posted that X will publish the code that determines both organic and advertising recommendations next week and will update it every four weeks with developer notes.
  • The pledge includes ad-targeting logic, expanding on a 2023 GitHub release that analysts viewed as partial and out of date.
  • European scrutiny has intensified, with the European Commission extending a retention order through 2026 and French authorities seeking details on X’s recommendation systems.
  • Grok’s image tools have generated sexualized material, including reports of CSAM and nonconsensual undressing, leading Indonesia to block Grok and UK leaders to demand fixes.
  • X is moving to deeper AI-driven curation, with plans for Grok to assess more than 100 million daily posts to personalize feeds, raising questions about oversight and transparency.
