What are embeddings in LLMOps?

Updated May 16, 2026

Short answer

Embeddings are dense vector representations of text used for semantic similarity search.

Deep explanation

Embeddings convert text into high-dimensional vectors capturing semantic meaning. Similar texts are placed closer in vector space. They are used in search, clustering, recommendation, and RAG systems.

Real-world example

Search engines finding similar support tickets.

Common mistakes

  • Using embeddings for exact keyword matching instead of semantic similarity.

Follow-up questions

  • What is cosine similarity?
  • Why not use raw text search?
