Agentdb Vector Search
High-performance vector search for RAG pipelines using AgentDB's HNSW indexing
What You Can Do
You can build production-grade vector search systems that retrieve semantically similar documents in sub-millisecond time using AgentDB's optimized HNSW indexing. The skill enables you to implement RAG pipelines, semantic search engines, and intelligent knowledge bases with configurable embedding dimensions, distance metrics (cosine, Euclidean, dot product), and similarity thresholds—all with built-in quantization and caching for massive performance gains.
Features
sub-millisecond search (<100µs) with 150x-12,500x faster retrieval than traditional databases
cosine similarity, Euclidean distance, and dot product calculations for flexible similarity matching
supports 384, 768, 1536+ dimensional embeddings across OpenAI, sentence-transformers, and custom models
optimized presets for small (<10K), medium (10K-100K), and large (>100K) vector collections
return only results above configurable similarity thresholds to control relevance
structured query results for seamless pipeline integration and automation
switch between fast in-memory databases for testing and persistent storage for production
automatic performance optimization for reduced memory footprint and faster repeated queries
Example Output
Query 1: Top 5 similar documents (cosine similarity)
