Chapter 1: Introduction to AI Image Generators

In this article, we delve into the most popular online image generators, including Stable Diffusion, Style Transfer, VQGAN-CLIP, CLIP-guided Diffusion, Dall-E 2, Dall-E Mini, MidJourney, and WomboArt, all accessible through NightCafe.

NightCafe provides users with four innovative tools:

• Stable Diffusion: An open-source alternative to Dall-E 2, it excels in creating highly realistic images from textual descriptions.
• Style Transfer: This tool enables you to choose two images—either uploaded by you or selected from examples—and transforms one based on the artistic patterns of the other.
• VQGAN-CLIP: A tool focused on generating images from prompts, emphasizing a more artistic approach.
• CLIP-guided Diffusion: Similar to CLIP, this offers enhanced control and improved composition for image creation.

Using NightCafe's tools requires tokens, which can be purchased, though you also receive five free tokens daily. Importantly, users retain copyright for their creations, making them suitable for commercial use and NFTs.

Here are some examples of images I created using prompts:

These are examples of graphics created using NightCafe based on photographs taken by me. The starting image on the left features lupins from a previous story, while the right image showcases an outpainting I created with Dall-E 2 using another photograph.

Chapter 2: The Power of Dall-E 2

Dall-E 2 has been widely discussed in the AI community:

Among the four tools available on NightCafe, Stable Diffusion closely resembles Dall-E 2 in its goal of producing realistic images. The debate over which tool is superior is ongoing, as image quality often depends on the prompts used and the subjective nature of artistic evaluation.

One advantage of Dall-E 2 over Stable Diffusion is the larger number of free credits available, allowing you to generate four distinct images for each token used.

To illustrate Dall-E 2's versatility, here are several images created simply from prompts:

Dall-E 2 also allows users to edit existing images, whether those are your own photographs or creations from other AI platforms. You can learn about the "inpainting" and "outpainting" processes in two insightful articles:

Chapter 3: Exploring Dall-E Mini and WomboArt

Dall-E Mini emerged as an open-source attempt to replicate Dall-E and Dall-E 2. You can access it online through Hugging Face spaces, although be cautious as the generated images may belong to a company called Craiyon. While it doesn't match Dall-E 2's quality, it can produce amusing images, allowing for nine creations each time without limitations.

Midjourney, another powerful tool, requires joining a Discord group to run prompts. Although it demands more effort than other tools, it is still accessible. For more information, check out Stella Sky’s Medium page, where she shares her passion for Midjourney.

I encourage you to unleash your creativity and generate images that encapsulate your most imaginative ideas! For those interested in these modern AI tools, explore related articles that discuss their capabilities and applications.
