Embed Text Chunk

When working with individual text chunks, you need to convert them into numerical vectors for similarity search. The embed method transforms a single text chunk into an embedding using your chosen provider and model.

import { openai } from '@ai-sdk/openai';
import { MDocument } from '@mastra/rag';
import { embed } from 'ai';
 
const doc = MDocument.fromText("Your text content...");
 
const chunks = await doc.chunk();
 
const { embedding } = await embed({
  model: openai.embedding('text-embedding-3-small'),
  value: chunks[0].text,
});
