Embeddings

Embeddings are numerical vector representations of text, code, images, or other data, arranged so that items with similar meaning sit close together in vector space. They turn fuzzy semantic similarity into a measurable distance.

They are the foundation of semantic search, clustering, recommendation, and retrieval for RAG: instead of matching exact words, a system compares meaning. The embedding model, its dimensionality, and the domain it was trained on largely determine retrieval quality.

The common trap is assuming one general-purpose model fits every domain — embeddings trained on web text often underperform on code, legal, or medical corpora, and mismatched query and document encoders quietly erode recall.
