Embedding

What it means

A numerical representation of information, such as text or images, that captures aspects of its meaning.

Code example

import OpenAI from "openai";
const openai = new OpenAI();
const res = await openai.embeddings.create({
  model: "text-embedding-3-small",
  input: "How does RAG work?",
});
console.log(res.data[0].embedding);

Why it matters

When to use it
