X平台正式开源推荐算法，马斯克称没有其他社交媒体公司这样做

Core Insights - Elon Musk announced the open-sourcing of the new X platform algorithm, which is powered by the same Transformer architecture as xAI's Grok model, emphasizing the need for significant improvements while promoting transparency in the development process [1][3]. Group 1: Algorithm Details - The X platform has open-sourced its "For You" recommendation algorithm, which is identical to the current production system and supported by xAI's Grok [3]. - The complete code has been published on GitHub and will be updated every four weeks [3]. - The recommendation content for users combines posts from followed accounts and posts discovered on X, utilizing a Grok-based transformer to rank them based on predicted user engagement [3]. Group 2: Model Functionality - The model predicts multiple user actions, such as likes, replies, reposts, clicks, and views, rather than a single score, allowing for more nuanced content ranking [3]. - The algorithm learns directly from user behavior, enhancing its predictive capabilities [3]. Group 3: Technical Components - The algorithm includes various components such as data fetching, filtering, scoring, and selection to optimize the user feed [5]. - The scoring mechanism employs a weighted approach to combine predictions from the Grok-based transformer, ensuring diverse content from different authors [5].
