X Opens Source Code: Transparency Tool Reveals Ranking Impact
13 Aug
Summary
- X released its 'For You' algorithm and ranking engine source code.
- A new tool lets users see how ranking systems affect their posts.
- The company aims to increase transparency and public trust.

X has dramatically expanded its open-source codebase, now including the "For You" timeline algorithm and its core ranking engine, released under the Apache v2 license on GitHub. This makes the codebase approximately 10 to 15 times larger than before, offering details on model configuration, filters, and ranking system parameters. The company also introduced a new transparency tool, "Under the Hood," accessible via the app's settings.
This tool enables users to download their aggregate stats as a JSON file, revealing if labels have been applied to their account or posts. Non-technical users can leverage Large Language Models to interpret this data by referencing X's GitHub repository. Initially a pilot for older accounts, the feature will roll out more broadly.
The initiative seeks to address ongoing concerns regarding X's algorithm's influence on politics and misinformation. By making its ranking code auditable and subject to critique, X aims to foster public trust and ensure a level playing field for content distribution, allowing for continuous improvement and fair assessment.
