What is OpenAI DALL·E?

DALL·E is a deep learning AI model developed by OpenAI that can generate digital images from natural language descriptions called prompts. In April 2022, DALL-E 2 was announced, and in September 2023, the latest DALL·E 3 model was released. Compared to DALL-E 2, DALL·E 3 is said to have significantly improved its understanding of prompts and the quality of generated images.

Comparing DALL-E 2 and DALL-E 3

Both DALL-E 2 and DALL-E 3 are AI image generation tools, but DALL-E 3 can generate much higher quality and more realistic images.

DALL-E 2 can create impressive images, but they often have a cartoonish look. On the other hand, DALL-E 3 has a highly refined understanding and can generate professional-quality images like iPhone app icons.

When comparing DALL-E 2 and DALL-E 3 using an app icon generator, DALL-E 3 produces much cleaner and more professional-looking results.

DALL-E 3 is integrated into Microsoft's Bing Image Creator tool, allowing it to generate high-quality images in seconds, potentially significantly improving the efficiency of traditional designers' work.

Additionally, DALL-E 3's advanced capabilities can be used in various fields, such as creating unique content for websites and social media, designing logos and branding materials, and more. If DALL-E 3's API is made available, even more innovative use cases are expected to emerge.

Using OpenAI DALL·E 3

With the release of DALL-E 3 as the successor to DALL-E 2, the DALL-E 2 model has been discontinued. According to OpenAI's official website, while DALL-E 2 is no longer accepting new users, past users are still allowed to use it.

How to Use DALL·E 3

For general users, accessing and using the DALL·E 3 service is straightforward, and it's available through various services.

Using DALL·E 3 with ChatGPT

In ChatGPT, you can directly use the DALL·E 3 service, but you'll need to subscribe to ChatGPT Plus.

About the DALL·E 3 API

The above sections introduced the basic information about OpenAI DALL·E and a guide for general users to use the OpenAI DALL·E service. Now, let's explore how to use the OpenAI DALL·E API if you want to leverage DALL·E's capabilities in a development setting. Since DALL-E 2 has been discontinued, we'll introduce a guide to using the DALL·E 3 API.

What DALL·E 3 API Can Do

The DALL·E 3 API is recognized as part of the OpenAI API and can enable image generation and editing functionality. The DALL·E 3 API can primarily perform the following operations:

  • Image generation: Generate images based on the input text
  • Image editing: Upload an existing image and edit it
  • Generate imitation images: Upload an existing image and generate a new image mimicking that image

DALL·E API Pricing

DALL·E 3 Pricing

According to the information published on OpenAI's official website, the pricing for the DALL·E 3 API is as follows:

  • Standard quality 1024x1024 resolution image: $0.040/image
  • Standard quality 1024x1792 or 1792x1024 resolution image: $0.080/image
  • HD quality 1024x1024 resolution image: $0.080/image
  • HD quality 1024x1792 or 1792x1024 resolution image: $0.120/image

DALL-E 3 is considered the highest quality model among these, and the higher the resolution and quality, the higher the price compared to DALL-E 2.

DALL·E 3 vs DALL·E 2 Pricing

DALL·E 2 Pricing

The pricing for DALL-E 2 is as follows:

  • 1024x1024 resolution image: $0.020/image
  • 512x512 resolution image: $0.018/image
  • 256x256 resolution image: $0.016/image

DALL-E 2 is a more cost-effective, lower-priced model, where the lower the resolution, the cheaper the price. For example, the lowest resolution of 256x256 images is the most affordable at $0.016 per image.

Using and Testing the DALL·E 3 API Online

Before using the DALL·E 3 API, you need to register for an OpenAI account and obtain an OpenAI API key.

Obtaining the OpenAI API Key

When you create an OpenAI account, you'll need to obtain an API key for authentication, which is a requirement for using the ChatGPT API. Follow these steps to obtain the ChatGPT API key:

Step 1: Access the OpenAI API Keys page and log in to your account (or create a new account if you don't have one).

Step 2: Click the "Create new secret key" button to generate a new API key.

Obtain OpenAI API Key

When you generate the API key, it will be immediately displayed on the screen. However, you won't be able to view it again, so it's recommended to record and store the API key securely.
