 *
 * 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({
