X Algorithm Upgrades to 'Phoenix' AI Architecture: Video Embeddings and Unified Recsys Revealed
xAI released major updates to the open-source X recommendation algorithm. The commit introduces the next-generation 'Phoenix (xrex)' recsys framework, video embedding hydrators, post v8 search embedding clients, and revamped safety label processing.
X Algorithm Update: Next-Gen Phoenix Pipeline, GPU Scorer Runtime, and Abuse Enforcement Integration
The latest open-source release integrates the next-generation 'Phoenix' candidate pipeline and scorer with a specialized GPU scoring runtime (BDSM). Key updates also introduce post-engager feature hydration, a zero-favorite codivert filter, and an overhaul of confidence-based abuse enforcement controls.
Open-Source X Recommendation Algorithm: Phoenix ML Integration, Immersive Video Scoring, and Visibility Filtering
The open-source X recommendation algorithm has been updated to detail the Phoenix-based candidate pipeline within the Rust home-mixer, dedicated immersive video scoring and carousel filtering, and an end-to-end visibility filtering subsystem governing content safety and action limitations.
Inside X's Open-Source Algorithm: Phoenix RecSys, Author Cold Start, and Mutual Follow Mechanics
A major open-source update to the X algorithm repository reveals the inner workings of the next-generation 'Phoenix (xrex)' neural recommendation framework, Rust-based Home Mixer enhancements for author cold-start scoring and mutual-follow metrics, and low-latency visibility filtering subsystems.
Open-Sourcing X's Recommendation Algorithm: Phoenix RecSys Engine & Visibility Filtering Breakdown
xAI has open-sourced the latest codebase for the X recommendation algorithm. This release details the Rust-based 'Phoenix' RecSys engine, the Home Mixer pipeline, and the comprehensive visibility filtering rules governing content moderation.
