LangChain 通过 ChatDeepInfra
包装器支持由 Deep Infra 托管的聊天模型。首先,您需要安装 @langchain/community
包
提示
- npm
- Yarn
- pnpm
npm install @langchain/community
yarn add @langchain/community
pnpm add @langchain/community
您需要获取 API 密钥并将其设置为名为 DEEPINFRA_API_TOKEN
的环境变量(或将其传递到构造函数中),然后按如下所示调用模型
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);
