# X Algorithm Explained

Interactive guide to the open-source X (Twitter) For You algorithm: candidate retrieval, Phoenix scoring, ranking weights, diversity, and cold start.

## What it explains

The site follows a recommendation candidate from retrieval through filtering, Phoenix action prediction, weighted scoring, author and network adjustments, diversity, and final visibility checks. It includes an interactive coefficient calculator, a source-linked quiz, and English and Russian editions.

- Coefficient comparisons assume equal predicted probability. They are not exchange rates between real actions and are not reach forecasts.
- The visible account-growth ranges are editorial planning bands, not ranking thresholds.
- The project does not claim access to private production parameters, experiments, or anti-abuse systems.
