@langchain/xai

This package contains the LangChain.js integrations for xAI.

Installation

npm install @langchain/xai @langchain/core

Chat models

This package adds support for xAI chat model inference.

Set the necessary environment variable (or pass it in via the constructor):

export XAI_API_KEY=

import { ChatXAI } from "@langchain/xai";
import { HumanMessage } from "@langchain/core/messages";

const model = new ChatXAI({
  apiKey: process.env.XAI_API_KEY, // Default value.
});

const message = new HumanMessage("What color is the sky?");

const res = await model.invoke([message]);

Development

To develop the @langchain/xai package, you'll need to follow these instructions:

Install dependencies

yarn install

Build the package

yarn build

Or from the repo root:

yarn build --filter=@langchain/xai

Run tests

Test files should live within a tests/ file in the src/ folder. Unit tests should end in .test.ts and integration tests should end in .int.test.ts:

$ yarn test
$ yarn test:int

Lint & Format

Run the linter & formatter to ensure your code is up to standard:

yarn lint && yarn format

Adding new entrypoints
