WatsonX AI
==========

LangChain.js supports integration with IBM WatsonX AI. Checkout [WatsonX AI](https://www.ibm.com/products/watsonx-ai) for a list of available models.

Setup[​](#setup "Direct link to Setup")
---------------------------------------

You will need to set the following environment variables for using the WatsonX AI API.

1.  `IBM_CLOUD_API_KEY` which can be generated via [IBM Cloud](https://cloud.ibm.com/iam/apikeys)
2.  `WATSONX_PROJECT_ID` which can be found in your [project's manage tab](https://dataplatform.cloud.ibm.com/projects/?context=wx)

Alternatively, these can be set during the WatsonxAI Class instantiation as `ibmCloudApiKey` and `projectId` respectively. For example:

    const model = new WatsonxAI({  ibmCloudApiKey: "My secret IBM Cloud API Key"  projectId: "My secret WatsonX AI Project id"});

Usage[​](#usage "Direct link to Usage")
---------------------------------------

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 { WatsonxAI } from "@langchain/community/llms/watsonx_ai";// Note that modelParameters are optionalconst model = new WatsonxAI({  modelId: "meta-llama/llama-2-70b-chat",  modelParameters: {    max_new_tokens: 100,    min_new_tokens: 0,    stop_sequences: [],    repetition_penalty: 1,  },});const res = await model.invoke(  "What would be a good company name for a company that makes colorful socks?");console.log({ res });
