¥See this section for general instructions on installing integration packages.

npm install @langchain/community @langchain/core

你需要获取 API 密钥并将其设置为名为 DEEPINFRA_API_TOKEN 的环境变量（或将其传递给构造函数），然后按如下所示调用模型：

¥You'll need to obtain an API key and set it as an environment variable named DEEPINFRA_API_TOKEN (or pass it into the constructor), then call the model as shown below:

import { ChatDeepInfra } from "@langchain/community/chat_models/deepinfra";
import { HumanMessage } from "@langchain/core/messages";

const apiKey = process.env.DEEPINFRA_API_TOKEN;

const model = "meta-llama/Meta-Llama-3-70B-Instruct";

const chat = new ChatDeepInfra({
  model,
  apiKey,
});

const messages = [new HumanMessage("Hello")];

const res = await chat.invoke(messages);

console.log(res);
