US EditionX Open Sources Its Algorithm: 5 Ways Businesses Can Benefit
X published the Grok-powered recommendation algorithm on GitHub with monthly updates to enhance transparency and address regulatory and user concerns.
- On January 19, 2026, X published its feed code, architecture diagram and write-up on GitHub under Apache 2.0, pledging to update the repository every four weeks.
- Elon Musk repeatedly argued X's algorithm was a 'black box,' and the 2023 partial open-source release exposed tangled 'spaghetti code,' drawing criticism from transparency advocates and critics.
- The GitHub write-up shows the system replaces manual feature engineering with a RecsysBatch input model scoring user history, redacts weighting constants, and enforces a strict Velocity window.
- Businesses should expect brands using X to must front-load engagement within minutes as delayed responses miss the velocity window, while Report/Block signals permanently suppress reach.
- Regulators have in recent weeks scrutinized Grok chatbot amid misuse allegations, while critics and OSINT researchers said the release omits crucial weights, leaving accountability doubts.
