*   Yarn
*   pnpm

    npm install cohere-ai @langchain/cohere

    yarn add cohere-ai @langchain/cohere

    pnpm add cohere-ai @langchain/cohere

    import { CohereEmbeddings } from "@langchain/cohere";/* Embed queries */const embeddings = new CohereEmbeddings({  apiKey: "YOUR-API-KEY", // In Node.js defaults to process.env.COHERE_API_KEY  batchSize: 48, // Default value if omitted is 48. Max value is 96});const res = await embeddings.embedQuery("Hello world");console.log(res);/* Embed documents */const documentRes = await embeddings.embedDocuments(["Hello world", "Bye bye"]);console.log({ documentRes });
