X, formerly known as Twitter, released its social recommendation algorithm under an Apache 2.0 open-source license, granting businesses commercial usage and modification rights, according to a VentureBeat report published January 20, 2026. The algorithm, which determines content visibility on the platform, is based on a "Transformer" architecture powered by xAI's Grok AI language model.
The move provides enterprises with insights into maximizing their promotional efforts and understanding how X evaluates posts and accounts. The open-sourcing aims to provide a "map" for businesses to navigate X's content distribution, potentially improving the ROI of their social media strategies, VentureBeat reported.
The new X algorithm replaces manual heuristic rules and legacy models. This release is significant for enterprises with brand accounts on X, or whose leaders and employees use X to post company public relations. The code and architecture are available on Github.
