提示

请参阅 关于安装集成软件包的一般说明。

npm

npm install @langchain/openai @langchain/core

Yarn

yarn add @langchain/openai @langchain/core

pnpm

pnpm add @langchain/openai @langchain/core

import { ChatOpenAI } from "@langchain/openai";
import { ConversationChain } from "langchain/chains";
import { MotorheadMemory } from "@langchain/community/memory/motorhead_memory";

// Managed Example (visit https://getmetal.io to get your keys)
// const managedMemory = new MotorheadMemory({
//   memoryKey: "chat_history",
//   sessionId: "test",
//   apiKey: "MY_API_KEY",
//   clientId: "MY_CLIENT_ID",
// });

// Self Hosted Example
const memory = new MotorheadMemory({
  memoryKey: "chat_history",
  sessionId: "test",
  url: "localhost:8080", // Required for self hosted
});

const model = new ChatOpenAI({
  model: "gpt-3.5-turbo",
  temperature: 0,
});

const chain = new ConversationChain({ llm: model, memory });

const res1 = await chain.invoke({ input: "Hi! I'm Jim." });
console.log({ res1 });
/*
{
  res1: {
    text: "Hello Jim! It's nice to meet you. My name is AI. How may I assist you today?"
