🍰 PromptLayer

The first platform built for prompt engineers

PromptLayer is the first platform that allows you to track, manage, and share your GPT prompt engineering. PromptLayer acts a middleware between your code and OpenAI’s JavaScript library.

PromptLayer records all your OpenAI API requests, allowing you to search and explore request history in the PromptLayer dashboard.

This repo contains the JavaScript wrapper library for PromptLayer.

Quickstart ⚡

Install PromptLayer

npm install promptlayer

Installing PromptLayer Locally

Use npm install . to install locally.

Using PromptLayer

To get started, create an account by clicking “Log in” on PromptLayer. Once logged in, click the button to create an API key and save this in a secure location (Guide to Using Env Vars).

export OPENAI_API_KEY=sk_xxxxxx
export PROMPTLAYER_API_KEY=pl_xxxxxx

Once you have that all set up, install PromptLayer using npm.

In the JavaScript file where you use OpenAI APIs, add the following. This allows us to keep track of your requests without needing any other code changes.

import BaseOpenAI from "openai";
import { PromptLayer } from "promptlayer";

const promptlayer = new PromptLayer({
  apiKey: process.env.PROMPTLAYER_API_KEY,
});
// Typescript
const OpenAI: typeof BaseOpenAI = promptlayer.OpenAI;
const openai = new OpenAI();

You can then use openai as you would if you had imported it directly.

Adding PromptLayer tags: pl_tags

PromptLayer allows you to add tags through the pl_tags argument. This allows you to track and group requests in the dashboard.

Tags are not required but we recommend them!

openai.chat.completions.create({
  messages: [{ role: "user", content: "Say this is a test" }],
  model: "gpt-3.5-turbo",
  // @ts-ignore
  pl_tags: ["test"],
});

Returning request id: return_pl_id

PromptLayer allows you to return the request id through the return_pl_id argument. When you set this to true, a tuple is returned with the request id as the second element.

openai.chat.completions.create({
  messages: [{ role: "user", content: "Say this is a test" }],
  model: "gpt-3.5-turbo",
  // @ts-ignore
  return_pl_id: true,
});

After making your first few requests, you should be able to see them in the PromptLayer dashboard!
