The open-source source code for X's (formerly Twitter) recommendation algorithm, a set of services and jobs that serve personalized feeds of posts across X product surfaces like the For You timeline, search, and notifications. It includes data pipelines, embedding models (SimClusters, TwHIN), trust-and-safety models, and serving frameworks such as product-mixer and navi.
Use cases
- understand how the X For You feed ranking works
- study large-scale recommendation systems in production
- learn how social media feeds are personalized
- research community detection and graph embeddings at scale
- build a recommendation service for a social feed
- study ML model serving architecture in Scala and Rust
When to choose
- you want to inspect or research a real production-scale recommendation algorithm
- you need reference implementations of candidate sourcing, ranking, and feed mixing
- you are studying social graph embeddings or user interaction prediction
When to avoid
- you want a plug-and-play recommendation library for your own app
- you need a small, self-contained project that runs without X's infrastructure
- you require a permissive license since it is AGPL-3.0
