What Is Embedding in RAG and Why Does It Use 1536 Dimensions?

The article explains that embedding converts text into a 1536‑dimensional floating‑point vector that serves as a semantic fingerprint, describes how the vector is generated, why 1536 dimensions are chosen, how similarity is measured, and provides Java Spring AI code examples along with model‑selection guidance and common interview pitfalls.
