const model = new ChatOpenAI();
const prompt =
  PromptTemplate.fromTemplate(`The following is a friendly conversation between a human and an AI. The AI is talkative and provides lots of specific details from its context. If the AI does not know the answer to a question, it truthfully says it does not know.

Human: {input}
AI:`);
const chain = new LLMChain({ llm: model, prompt, memory });

const res1 = await chain.call({ input: "Hi! I'm Jim." });
console.log({ res1, memory: await memory.loadMemoryVariables({}) });

const res2 = await chain.call({ input: "What's my name?" });
console.log({ res2, memory: await memory.loadMemoryVariables({}) });
