# Update February 1, 2023 <!-- omit in toc -->

This package no longer requires any browser hacks – **it is now using the official OpenAI completions API** with a leaked model that ChatGPT uses under the hood. 🔥

```ts
import { ChatGPTAPI } from 'chatgpt'

const api = new ChatGPTAPI({
  apiKey: process.env.OPENAI_API_KEY
})

const res = await api.sendMessage('Hello World!')
console.log(res.text)
```

Please upgrade to `chatgpt@latest` (at least [v4.0.0](https://github.com/transitive-bullshit/chatgpt-api/releases/tag/v4.0.0)). The updated version is **significantly more lightweight and robust** compared with previous versions. You also don't have to worry about IP issues or rate limiting!

Huge shoutout to [@waylaidwanderer](https://github.com/waylaidwanderer) for discovering the leaked chat model! 💪

If you run into any issues, we do have a pretty active [Discord](https://discord.gg/v9gERj825w) with a bunch of ChatGPT hackers from the Node.js & Python communities.

Lastly, please consider starring this repo and <a href="https://twitter.com/transitive_bs">following me on twitter <img src="https://storage.googleapis.com/saasify-assets/twitter-logo.svg" alt="twitter" height="24px" align="center"></a> to help support the project.

Thanks && cheers,

## Intro

This package is a Node.js wrapper around [ChatGPT](https://openai.com/blog/chatgpt) by [OpenAI](https://openai.com). TS batteries included. ✨

You can use it to start building projects powered by ChatGPT like chatbots, websites, etc...

## Install

```bash
npm install chatgpt
```

Make sure you're using `node >= 18` so `fetch` is available (or `node >= 14` if you install a [fetch polyfill](https://github.com/developit/unfetch#usage-as-a-polyfill)).

## Usage

Sign up for an [OpenAI API key](https://platform.openai.com/overview) and store it in your environment.

```ts
import { ChatGPTAPI } from 'chatgpt'

async function example() {
  const api = new ChatGPTAPI({
    apiKey: process.env.OPENAI_API_KEY
  })

  const res = await api.sendMessage('Hello World!')
  console.log(res.text)
}
```

If you want to track the conversation, use the `conversationId` and `id` in the result object, and pass them to `sendMessage` as `conversationId` and `parentMessageId` respectively. `parentMessageId` is the most important parameter for recalling previous message context.

```ts
const api = new ChatGPTAPI({ apiKey: process.env.OPENAI_API_KEY })

// send a message and wait for the response
let res = await api.sendMessage('What is OpenAI?')
console.log(res.text)

// send a follow-up
res = await api.sendMessage('Can you expand on that?', {
  conversationId: res.conversationId,
  parentMessageId: res.id
})
console.log(res.text)

// send another follow-up
res = await api.sendMessage('What were we talking about?', {
  conversationId: res.conversationId,
  parentMessageId: res.id
})
console.log(res.text)
```

You can add streaming via the `onProgress` handler:

```ts
// timeout after 2 minutes (which will also abort the underlying HTTP request)
const res = await api.sendMessage('Write a 500 word essay on frogs.', {
  // print the partial response as the AI is "typing"
  onProgress: (partialResponse) => console.log(partialResponse.text)
})

// print the full text at the end
console.log(res.text)
```

You can add a timeout using the `timeoutMs` option:

```ts
// timeout after 2 minutes (which will also abort the underlying HTTP request)
const response = await api.sendMessage(
  'write me a really really long essay on frogs',
  {
    timeoutMs: 2 * 60 * 1000
  }
)
```

If you want to see more info about what's actually being sent to [OpenAI's completions API](https://platform.openai.com/docs/api-reference/completions), set the `debug: true` option in the `ChatGPTAPI` constructor:

```ts
const api = new ChatGPTAPI({
  apiKey: process.env.OPENAI_API_KEY,
  debug: true
})
```

You'll notice that we're using a reverse-engineered `promptPrefix` and `promptSuffix`. You can customize these via the `sendMessage` options:

```ts
const res = await api.sendMessage('what is the answer to the universe?', {
  promptPrefix: `You are ChatGPT, a large language model trained by OpenAI. You answer as concisely as possible for each response (e.g. don’t be verbose). It is very important that you answer as concisely as possible, so please remember this. If you are generating a list, do not have too many items. Keep the number of items short.
Current date: ${new Date().toISOString()}\n\n`
})
```

Note that we automatically handle appending the previous messages to the prompt and attempt to optimize for the available tokens (which defaults to `4096`).

<summary>Usage in CommonJS (Dynamic import)</summary>

```js
async function example() {
  // To use ESM in CommonJS, you can use a dynamic import
  const { ChatGPTAPI } = await import('chatgpt')

  const api = new ChatGPTAPI({ apiKey: process.env.OPENAI_API_KEY })

  const res = await api.sendMessage('Hello World!')
  console.log(res.text)
}
```

</details>

### Docs

See the [auto-generated docs](./docs/classes/ChatGPTAPI.md) for more info on methods and parameters.

### Demos

To run the included demos:

1. clone repo
2. install node deps
3. set `OPENAI_API_KEY` in .env

A [basic demo](./demos/demo.ts) is included for testing purposes:

```bash
npx tsx demos/demo.ts
```

A [demo showing on progress handler](./demos/demo-on-progress.ts):

```bash
npx tsx demos/demo-on-progress.ts
```

The on progress demo uses the optional `onProgress` parameter to `sendMessage` to receive intermediary results as ChatGPT is "typing".

A [conversation demo](./demos/demo-conversation.ts):

```bash
npx tsx demos/demo-conversation.ts
```

Lastly, a [persitence demo](./demos/demo-persistence.ts) shows how to store messages in Redis for persistence:

```bash
npx tsx demos/demo-conversation.ts
```

Any [keyv adaptor](https://github.com/jaredwray/keyv) is supported for persistence, and there are overrides if you'd like to use a different way of storing / retrieving messages.

Note that persisting message is very important for remembering the context of previous conversations.

## Compatibility

- This package is ESM-only.
- This package supports `node >= 14`.
- This module assumes that `fetch` is installed.
  - In `node >= 18`, it's installed by default.
  - In `node < 18`, you need to install a polyfill like `unfetch/polyfill` ([guide](https://github.com/developit/unfetch#usage-as-a-polyfill))
- If you want to build a website using `chatgpt`, we recommend using it only from your backend API
