Twitter has opened most of its source code to the global community, and has released two new repositories (main repo, ml repo) on GitHub, including the recommendation algorithm (controlling the For You timeline), but currently does not include the code that provides support for ad recommendations . Twitter said it took additional steps to ensure user safety and privacy are protected, including deciding not to release training data or model weights related to Twitter's algorithm at this time. Twitter CEO Elon Musk (Elon Musk) Musk said that Twitter will update the recommendation algorithm every 24 to 48 hours based on user suggestions.
