Step-by-Step Implementation

1. Setting Up the AI Model

import { OpenAI } from 'openai'
import { ChatOpenAI } from 'langchain/chat_models/openai'
const chatModel = new ChatOpenAI({
  openAIApiKey: process.env.OPENAI_API_KEY,
  modelName: 'gpt-4o',
  temperature: 0.7
})

2. Creating Conversation Memory

import { ConversationBufferMemory } from 'langchain/memory'
const memory = new ConversationBufferMemory({
  memoryKey: 'chat_history',
  returnMessages: true
})

3. Building the Chain

import { ConversationChain } from 'langchain/chains'
const chain = new ConversationChain({
  llm: chatModel,
  memory: memory,
  verbose: true
})
