FAQPage Schema
How do I run fast similarity search on large embedding datasets?

FAISS enables fast similarity search on large embedding datasets by indexing dense vectors and performing nearest neighbor retrieval. You can choose from multiple index types like Flat, IVF, HNSW, or PQ based on scale and accuracy needs.

Can I use GPU acceleration for vector search?

GPU acceleration for vector search is fully supported. FAISS offloads computation to GPUs to process large-scale embedding stores efficiently, accelerating nearest neighbor retrieval across massive datasets.

What's the best way to index billions of vectors for nearest neighbor search?

The best way to index billions of vectors for nearest neighbor search is using approximate index types like IVF, HNSW, or PQ. FAISS provides high-performance indexing to scale dense vector retrieval across massive datasets.

Does FAISS work with Python bindings for ML pipeline integration?

Yes, FAISS works with Python bindings for seamless ML pipeline integration. It allows you to incorporate vector similarity search and clustering into existing Python workflows for large-scale retrieval tasks.

When should I choose approximate search over exact search for embeddings?

Choose approximate search over exact search for embeddings when querying massive datasets where speed is critical. FAISS provides end-to-end demos for both approaches, allowing trade-offs between accuracy and retrieval latency.
