  • Scalable k-NN search on billions of vectors with CPU/GPU support for low latency.
  • Large-scale vector retrieval for NLP, computer vision, and recommender systems.
  • Use case: semantic search over massive document collections or image similarity tasks.

Quick Start

Install FAISS (faiss-cpu or faiss-gpu) and create an index to add vectors and run a search.

Frequently Asked Questions about faiss

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I run similarity search on billions of dense vectors?▼

Similarity search on billions of dense vectors is achieved by building scalable FAISS indexes that support k-NN retrieval across CPU and GPU environments. It handles large-scale vector clustering and retrieval with low latency.

What is the best way to perform k-NN search for NLP and computer vision applications?▼

The best way to perform k-NN search for NLP and computer vision applications is creating a FAISS index to add dense vectors and run fast retrieval. It supports multiple index types like Flat, IVF, and HNSW for high-performance tasks.

Does FAISS support GPU acceleration for large-scale vector retrieval?▼

FAISS supports GPU acceleration for large-scale vector retrieval by using the faiss-gpu library. This enables efficient similarity search and clustering on massive dense vector datasets with significantly lower latency.

Which index types can I use for clustering dense vector datasets?▼

You can use multiple FAISS index types for clustering dense vector datasets, including Flat, IVF, and HNSW. These indexes allow efficient similarity search and k-NN operations on both CPU and GPU execution modes.

Do I need numpy installed to use FAISS for semantic search?▼

You need numpy installed alongside the FAISS library (faiss-cpu or faiss-gpu) to use it for semantic search. These dependencies are required to process dense vector datasets and perform efficient similarity search.

When should I use FAISS over other tools in the same category?▼

You should use FAISS over other tools in the same category when you need billion-scale vector retrieval with GPU acceleration. It provides multiple index types for efficient similarity search and clustering on dense vector datasets where other tools may lack scalability.
