Can I use ChatOpenAI to reply based on the information in the document I provided?

For example reading archives from csv, json or Web Loaders
Use ChatOpenAI to ask questions, reply based on the profile I provide

I tried it out, share it with everyone

`import { ChatOpenAI } from "langchain/chat_models";

openAIApiKey: chatgptKey,

//load csv

1,Harrison went to Harvard.

*/
const loader = new CSVLoader("public/example.csv");
const docs = await loader.load();

/* Create the vectorstore */
let vectorStore;
vectorStore = await HNSWLib.fromDocuments(docs, new OpenAIEmbeddings({openAIApiKey: chatgptKey}));
// Save the vector store to a directory
const directory = "public/vc";
await vectorStore.save(directory);

const chain = RetrievalQAChain.fromLLM(model, vectorStore.asRetriever());
const res = await chain.call({
input_documents: docs,
query: "Where did Ankush go to college??",
});
console.log({ res }); //{ res: { text: 'Ankush went to Princeton.' } }
}
v_chat2();`
