Function convertPromptToOpenAI

Convert a formatted LangChain prompt (e.g. pulled from the hub) into a format expected by OpenAI's JS SDK.

Example

import { convertPromptToOpenAI } from "langsmith/utils/hub/openai";
import { pull } from "langchain/hub";

import OpenAI from 'openai';

const prompt = await pull("jacob/joke-generator");
const formattedPrompt = await prompt.invoke({
  topic: "cats",
});

const { messages } = convertPromptToOpenAI(formattedPrompt);

const openAIClient = new OpenAI();

const openaiResponse = await openAIClient.chat.completions.create({
  model: "gpt-4o",
  messages,
});
