Voyage AI
=========

The `VoyageEmbeddings` class uses the Voyage AI REST API to generate embeddings for a given text.

    import { VoyageEmbeddings } from "langchain/embeddings/voyage";const embeddings = new VoyageEmbeddings({  apiKey: "YOUR-API-KEY", // In Node.js defaults to process.env.VOYAGEAI_API_KEY});
