What is AI Image Generation ?
AI technology has long been used to generate unique content, such as art, literature and music by following specific rules and guidelines. However, the latest AI image generator tools have taken this ability to a new level, allowing machines to create any imaginable image almost instantly.
AI-generated images refer to images that are created using artificial intelligence algorithms and technology. This type of image is created by a computer program rather than a human, and can take many different forms such as painting, drawings, art, etc.
The image generator produces high-quality output, making it an excellent tool for enhancing creativity in visual content. It can be applied in various fields such as marketing, advertising, and blogging.
How does AI Image Generation work?
AI image generation uses machine learning algorithms to generate images that are similar to the ones in a given dataset. That’s why GANs (generative adversarial networks) have become one of the most common techniques used in image generation.
GANs use a two-part neural network architecture, consisting of a generator and a discriminator that work together in an adversarial manner to produce new images. GANs are well known for generating high-quality images due to their deep understanding of a wide range of artistic styles and techniques.
However, another type of generative AI model, called Diffusion Model, has gained popularity in recent years. The model generates images by iteratively updating a set of noisy pixels with a diffusion process. In simpler terms, Diffusion model generates images by gradually adding more and more details to the initial noise, resulting in high-quality images with sharp details even for large-scale images.
On the other hand, variational autoencoders (VAEs) are also leveraged in image generation technology. It works by encoding images into a lower-dimensional space and then decoding them back into images. VAEs can produce variations on a given style or theme, but their quality may not be as high as GANs or diffusion models.
In comparison, GANs are generally considered a popular technique for generating high-quality and realistic images due to their comprehensive training on vast image datasets. Diffusion models have shown promising results in creating abstract or surreal images, while VAEs are useful for generating images similar to the training set, but not necessarily exact copies.
Features of image generation
Image generation includes a lot of different features, depending on the provider and the current technologies that they have. Here are some of the most common features:
- Generating images from text input, also called text-to-image generation
- Generating images that are similar to a given image, also called image-to-image translation
- Generating art
- Removing background
- Removing objects out of the images
- Inpainting images
- Increasing resolution
- Images Colorization

MidJourney
MidJourney is considered one of the best AI image generators, with comprehensive capabilities and extremely fast image generation. Input a text prompt and let Midjourney do the rest.
Unlike other AI image generators, Midjourney will generate pictures of celebrities and public figures. One possible drawback to Midjourney is that the software is extremely stylized as an AI text-to-image generator. This makes it nearly impossible to create photorealistic images on Midjourney. However, the system was never designed to create realistic-looking imagery and this is an important part of Midjourney’s philosophy as an AI generator.
However, at the moment, Midjourney is hosted on a Discord server. To generate images with MidJourney, you have to join his server and employ Discord bot commands to create images.
NightCafe
NightCafe is the ideal AI text-to-image generator that allows you to create authentic and creative images using simple words. With this tool, you can easily generate custom photos by describing what you want using basic English. Furthermore, NightCafe offers a variety of styles and options for generating diverse digital art. For example, it includes a neural style transfer feature that can convert actual photos into artistic creations.
Its easy-to-use software makes it accessible even for beginners. The visually appealing and convenient website interface allows users to quickly and easily create and edit images with one click.
NLP Cloud
NLP Cloud's API provides a cutting-edge approach to generating synthetic images from textual descriptions using Stable Diffusion model. The API uses state-of-the-art deep learning models to interpret natural language input and generate corresponding images with high fidelity.

Differences and similarities between all those Image generators
After testing the AI image generator of various providers, several similarities and differences were observed.
It has been noticed that each AI image generator has its own default style. Some, such as NightCafe tend to produce more realistic images, while others like NLP Cloud, generate images with a more drawing-like appearance. For instance, Dream by WOMBO is highly adept at producing anime-style output, regardless of the input given:
Other providers, however, perform better in varying styles depending on the input given. Some even offer the possibility to select a specific style such as drawing, realism, fantasy, anime, and so on.
Then, when specifying the desired style, there is also a significant amount of differences between the different providers.
Selection of a specific style
For instance, when selecting the abstract style on Dream by Wombo and Deep AI, it can be observed that Dream generates a 2D image, while DeepAI produces more of a 3D style image
Text Prompt
It's worth noting that the level of detail provided in the text prompt significantly affects the accuracy of the generated image. For instance, when creating a portrait, including extensive details about the subject's appearance and surroundings allows all providers, regardless of style, to accurately follow the given input text.
Image Prompt
Several AI image generators provide the option to upload a reference image directly from a computer, in addition to entering a text prompt. This feature enables the AI to use the uploaded image as a starting point for the ultimate output.
Dream by WOMBO provides a feature that allows users to adjust the degree of impact that the reference image will have on the final artwork. For instance, we utilized Starry AI to modify the Eden AI logo by supplying them with the image and specific prompts such as "draw animals" or "draw robots":
Image-to-Image feature
In addition to the widely used text-to-image functionality, various providers now include an image-to-image feature.
NightCafe, for instance, offers a style transfer option that enables users to upload an image and select a desired style. The AI then modifies the original image to match the chosen style, providing a fresh avenue for user creativity to transform the appearance and ambiance of their images.
Below are three distinct styles in which the Eden AI logo was transformed:
