Semantic Search At LinkedIn
LinkedIn's new AI search finds jobs and people by meaning, not just keywords, making results far more relevant.
Deep Dive
LinkedIn has built a new AI search system that understands the meaning of queries, not just keywords. It uses a large language model to judge relevance and a smaller, efficient model trained by the larger one to rank results. A specialized architecture makes it over 75 times faster while maintaining high-quality results. This enables one of the first production LLM-based ranking systems, improving search quality and user engagement for jobs and people.
Why It Matters
This makes professional networking and job hunting more intuitive and effective for millions of users.
