AlephAlpha
==========

LangChain.js supports AlephAlpha's Luminous family of models. You'll need to sign up for an API key [on their website](https://www.aleph-alpha.com/).

Here's an example:

tip

See [this section for general instructions on installing integration packages](/v0.2/docs/how_to/installation#installing-integration-packages).

*   npm
*   Yarn
*   pnpm

    npm install @langchain/community

    yarn add @langchain/community

    pnpm add @langchain/community

    import { AlephAlpha } from "@langchain/community/llms/aleph_alpha";const model = new AlephAlpha({  aleph_alpha_api_key: "YOUR_ALEPH_ALPHA_API_KEY", // Or set as process.env.ALEPH_ALPHA_API_KEY});const res = await model.invoke(`Is cereal soup?`);console.log({ res });/*  {    res: "\nIs soup a cereal? I don’t think so, but it is delicious."  } */

#### API Reference:

*   [AlephAlpha](https://v02.api.js.langchain.com/classes/langchain_community_llms_aleph_alpha.AlephAlpha.html) from `@langchain/community/llms/aleph_alpha`
