Author infoRatingReview Summary
Senior Software Engineer4.0I've used Faiss for a year in a retrieval-augmented generation project with Cohere and OpenAI; it’s fast, integrates well, and accurate, though limited by in-memory storage and lacks persistent storage or visualization of embeddings.
Student at Otto-von-Guericke-Universitaet4.5I created vectors and embeddings using Hugging Face and used Faiss for query searches. Although I found Faiss valuable as a basic database, I wish I could customize algorithms to compare query mechanisms for better results.
CEO & President at Ideyatech, Inc3.5We use Faiss for document tasks in augmented generation. It requires additional tools for smoother production integration and improvement in handling larger datasets. We previously evaluated Milvus and are currently exploring Chroma for a potential alternative.
