Embedding
A numerical vector representation of text, image or audio that captures meaning for similarity search.
/ quick answer
An Embedding is a fixed-length vector produced by a model so that semantically similar inputs sit close together in vector space. Embeddings power semantic search, clustering, classification, deduplication and the retrieval step of RAG. A numerical vector representation of text, image or audio that captures meaning for similarity search.

What is Embedding?
An Embedding is a fixed-length vector produced by a model so that semantically similar inputs sit close together in vector space. Embeddings power semantic search, clustering, classification, deduplication and the retrieval step of RAG.
What is an example of Embedding?
Embed every paragraph in your docs once, store the vectors, then at query time embed the user's question and return the closest paragraphs — even if they share no exact keywords.
Why does Embedding matter?
