·2026.11.11 02:00
Key point
The system uses LLMs to validate user-stated interests and apply them responsively to ranking and delivery, balancing new content visibility with existing engagement.
Details
- Meta launched 'Your Algorithm,' a suite of AI-powered tools that allows users to personalize Facebook Feed and Reels recommendations using natural language inputs.
- The system features a single editable view with 'Interested In' and 'Not Interested In' lists, plus a 'Lately Summary' generated by LLMs to describe recent viewing activity.
- LLMs are tailored to specific tasks: profile generation creates initial interest profiles, preference management validates edits using smaller models for efficiency, and a fine-tuned LLM reranker performs final checks against 'Not Interested In' topics.
- Delivery optimization includes a 'supplementary tail load' for new interests to fetch fresh content quickly and cache invalidation on the device to remove content matching newly added exclusions.
- Ranking logic balances new interests by capping daily contribution and spacing out recommendations, ensuring new topics appear without crowding out other content.
- Evaluation of LLM performance uses a separate LLM judge to grade outputs against expected behavior, providing an objective metric for comparing prompts and models before launch.
