X open-sources its timeline ranking code and adds a shadowban check
X published the code behind its default timeline and core ranking engine on GitHub under Apache v2 — model configuration, filters, and the signal weights that decide which posts surface — making the open codebase 10 to 15 times larger than before. A new settings page lets accounts that posted 10 or more times in the past month download a JSON file of labels applied to their account or posts, so a developer can audit ranking outcomes against the published weights and submit pull requests to the algorithm. Systems that use Grok to predict rule violations stay closed; VP of Product Keith Coleman cited spam-evasion risk.

You can see the systems that filter out potentially problematic, rule-violating content…And some of those systems, like the ranker and the score, you can even run yourself outside the company.
Why this matters
- → Users can now audit how X's algorithm ranks their posts against published weights.
- → Opens development of ranking improvements via public pull requests.
- → Addresses long-standing political shadowban allegations with verifiable code.
