X Open Sources Its Feed Algorithm

14AUG
10X BIGGERTHE ALGOYOUR FILE

The shadowban debate just got receipts. X published its For You ranking code on GitHub, plus a tool showing whether its systems throttled your account. Every label, downloadable as a file.

The release is 10 to 15 times bigger than X's last code drop. It includes the ranker, filters, and the signal weights that decide what you see.

A new Under the Hood settings page lets active users download their moderation labels as a JSON file. Product chief Keith Coleman says people will be 'fairly shocked' X released this. Outside researchers already ran the scoring system.

One catch: the Grok-based rule-violation systems stay closed, so spammers can't reverse-engineer them. Trust the transparency up to that line.

full brief & sources

⚡ Why this matters

  • Shadowbanning went from conspiracy theory to a checkable claim. That's new for any major platform.
  • Feed algorithms decide political reach. Auditable code changes that debate.
  • No other big social platform lets users download their own moderation labels.

🔍 What happened

  • Aug 13 - X published its For You feed code on GitHub under an Apache license.
  • The release includes the core ranker, content filters, and the signal weights behind feed decisions.
  • An Under the Hood settings page lets users with 10+ monthly posts download their account and post labels as JSON.
  • The pilot starts with accounts at least one year old.
  • External researchers trained and ran X's Phoenix scoring system from the public code before launch.
  • Developers can submit pull requests that X engineers may merge into the live algorithm.

💬 Smart takes

  • Keith Coleman, X VP of Product: 'This is the kind of thing that I think people will be fairly shocked that we are releasing.'
  • Coleman again: 'How cool would it be for the X algorithm to be not just visible to the public, but also, like, by the public?'
  • Skeptic: X got less transparent as a company under Musk. Metrics, revenue, and takedown reporting all shrank. Open code is one lens, not the whole picture.

🧭 Where this goes

  1. Likelyshadowban JSON screenshots become a viral format within weeks. Users feed the file to a chatbot for a verdict.
  2. Likelyresearchers publish independent audits of the ranking weights within months.
  3. Possiblea rival platform matches this with its own transparency tools.
  4. Wild Carda regulator cites X's downloadable labels as the template for mandated algorithmic transparency.

🥄 The Spoon Take

Every platform says trust us. X just said check for yourself. The interesting part isn't the code drop, it's the personal moderation file. Once users can see their labels, every other feed's opacity starts to look like a choice.

🤔 Pushback

The Grok moderation layer stays closed, and that's exactly where most invisible enforcement lives. The receipts may not cover the thing people are angriest about.
