## AI overview

Neon describes how parallel HNSW index builds in pgvector can reduce vector index build time by 30x. The article explains how Neon's elastic, separate-storage-and-compute architecture can allocate extra resources during indexing and scale them down afterward for AI applications using vector search, semantic search, and Retrieval Augmented Generation.

## Source excerpt

We are Neon, the serverless Postgres. We power thousands of AI apps with the pgvector extension and separate storage and compute enabling your database resources to scale independently. In this article, Raouf explains how you can use Neon's elasticity, and parallel HNSW index bui...
