Safety

Want to know how your posts are distributed on X? You don’t have to take our word for it:

• For You Algorithm: Open-source so anyone can study how X’s feed ranking works. github.com/xai-org/x-algo…

• Under The Hood Reports: Think you're "shadowbanned"? Check if any labels are limiting your account or posts in For You — and critique if something looks off. x.com/i/jf/under_the…

• Legal & Country Restrictions: Under The Hood reports also show if a government demand or legal request is restricting your reach, and in which country.

And we’re working on more…

“Published rules tell you what should happen. Transparency shows you what happened. But neither, on its own, proves that a system is working consistently at scale. Verification does.”

Michael O’Herlihy at the Brand & AI Safety Summit today: open systems and controls people can see matter for both safety and advertiser confidence.

Head of Safety @michaelo will be at the Brand & AI Safety Summit next week speaking on why open-source recommender systems and controls people can see matter for safety and accountability.

In August, X open-sourced the code that affects a post’s visibility in the For You feed – including ranking, model configuration, filters, and core systems. The repository is publicly available, updated regularly, and accepts pull requests from outside contributors.

Alongside the open-sourced code, Under the Hood gives eligible users aggregate data on any visibility-limiting labels applied to their account or posts, including cases driven by local legal demands.

Together they make the system inspectable. That is the standard.

Excited to have Michael O’Herlihy as the new Head of Safety at X. He’ll lead our work to keep people and brands safe across the platform and our AI systems, while protecting free expression and making Safety more transparent.

@michaelo will be at the Brand & AI Safety Summit in New York next Tuesday November 10 making the case for why open systems and controls people can see matter for both safety and advertiser confidence.
