This package contains the LangChain.js integrations for xAI.
npm install @langchain/xai @langchain/core
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]);
To develop the @langchain/xai package, you'll need to follow these instructions:
pnpm install
pnpm build
Or from the repo root:
pnpm build --filter @langchain/xai
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:
$ pnpm test
$ pnpm test:int
Run the linter & formatter to ensure your code is up to standard:
pnpm lint && pnpm format
If you add a new file to be exported, either import & re-export from src/index.ts, or add it to the exports field in the package.json file and run pnpm build to generate the new entrypoint.
