DALL·E 2, the sequel to the original DALL·E by OpenAI, stands tall among AI image generators with its accessible, user-friendly design and relatively affordable pricing model.

DALL·E 2 offers several advanced features under its simple exterior. Its in-beta image editor allows you to add additional AI-generated frames, or 'out-painting', and you can erase parts of an image and replace them with AI-rendered elements, a technique known as 'in-painting'. These features unlock a whole new avenue for creating larger, intricate AI artwork.

Users can sign up for a free OpenAI account and dive into the creative process without any complex setup or steep learning curve. Type in your desired concept and with a swift click on the 'Generate' button, you'll be rewarded with four variations of AI-crafted images in mere seconds. The simplicity of the user interface parallels the ease of using ChatGPT, another renowned OpenAI tool.

On signing up, users are gifted with 50 free credits, along with a recurring bonus of 15 free credits every month. Each credit empowers you to generate four image variations from a single prompt, which could range from a written prompt to an image upload. The budget-conscious will appreciate the pricing; a mere $0.13 per prompt or $0.0325 per image variation.

For developers, OpenAI offers an API that integrates with DALL·E 2, paving the way for automation tools like Zapier. This interconnectivity allows DALL·E 2 to work in tandem with other applications such as Google Forms or HubSpot, automating the creation of images from responses or even automating art inspiration.
