EMBEDDINGS: SEMANTIC UNDERSTANDING

Converting Text to Vectors for AI Applications

By UDDIT, Embedding Models Expert & AI Engineer

WHAT ARE EMBEDDINGS?

Embeddings convert text into numerical vectors that capture semantic meaning. They are the foundation of RAG systems, semantic search, and modern AI applications. The quality of your embeddings directly determines the quality of your AI application's understanding.

✎ EDITOR'S NOTE

"Embeddings are the secret sauce that enables AI to understand meaning, not just keywords."

HOW EMBEDDINGS WORK

  • ■ Text input is tokenized
  • ■ Neural network processes tokens
  • ■ Output: dense vector (e.g., 1536 dims)
  • ■ Similar meanings = similar vectors
  • ■ Enables similarity search
