Adding a timeout
================

By default, LangChain will wait indefinitely for a response from the model provider. If you want to add a timeout, you can pass a `timeout` option, in milliseconds, when you call the model. For example, for OpenAI:

tip

See [this section for general instructions on installing integration packages](/v0.1/docs/get_started/installation/#installing-integration-packages).

*   npm
*   Yarn
*   pnpm

    npm install @langchain/openai

    yarn add @langchain/openai

    pnpm add @langchain/openai

    import { ChatOpenAI } from "@langchain/openai";import { HumanMessage } from "@langchain/core/messages";const chat = new ChatOpenAI({ temperature: 1 });const response = await chat.invoke(  [    new HumanMessage(      "What is a good name for a company that makes colorful socks?"    ),  ],  { timeout: 1000 } // 1s timeout);console.log(response);// AIMessage { text: '\n\nRainbow Sox Co.' }
