Recommendation System for X's For You Feed

x-algorithm is a repository that contains the core recommendation system powering the "For You" feed on X. This system integrates in-network content from accounts users follow with out-of-network content discovered through machine learning-based retrieval, utilizing a Grok-based transformer model for ranking.

Key features:

• In-Network Content - Retrieves posts from accounts users follow.
• Out-of-Network Content - Discovers posts from a global corpus using ML-based similarity search.
• Scoring and Ranking - Uses engagement history to predict relevant content.
• Candidate Pipeline - A reusable framework for building recommendation pipelines.
• Real-time Ingestion - Tracks recent posts with sub-millisecond lookups.

This repository is designed for developers and researchers interested in recommendation systems, providing insights into the architecture and functionality of the algorithm.
