The Complete Guide to AI Image Generators (Including the Best Options in 2023)

AI image generators are powerful tools to unlock your creative potential and create engaging visuals with ease. You don’t need any technical know-how or prior experience in art to produce amazing artwork. 

As a creator, using an AI image generator gives you lots of artistic freedom. Instead of using the same stock photos as everyone else, you can give your brand a unique look without investing much time or effort.

In this article, we explain everything you need to know about AI image generators, including how they work, their limitations, and best practices to use them effectively. 

What is an AI Image Generator?

An AI Image Generator is a type of software application that uses artificial intelligence (AI) and machine learning (ML) techniques to create or generate new images. These AI image generators can create images from scratch or transform existing images into new ones by using various algorithms and techniques.

AI image generators are typically based on deep learning neural networks that are trained on a large dataset of images. The neural network can then be used to generate new images by predicting pixel values based on the patterns it has learned from the training data.

Here are some examples of realistic portraits created with Midjourney V5 by CineD.

Some common applications of AI image generators include generating realistic images of people, animals, or objects, creating artwork, generating new designs, and enhancing or modifying existing images. AI image generators can also be used in a variety of industries, including entertainment, marketing, fashion, and healthcare.

How Using an AI Image Generator Works

While AI image generators are exceedingly complex pieces of software, they aren’t hard to use. 

Your first step is to choose a generator that meets your needs. They all have their own strengths and weaknesses. We outline several of the top options later in this article. 

Next, you’ll need to provide some input. Depending on the tool you decide to use, this may involve typing text parameters, or you may need to submit similar images to give the generator some context.

After providing input parameters, the AI image generator will create a new image based on those parameters. Depending on the complexity of the image and the AI image generator being used, this may take anywhere from a few seconds to several minutes.

The first image produced is almost never suitable, so you’ll need to refine your parameters or submit additional images to help the AI understand.

Over time, you’ll get better at providing the right input to get the output you’re looking for. Using an AI image generator is a unique blend of art and science, just like using an AI text generator. 

The Different Types of AI Image Generators

There are several types of AI image generators that are commonly used today. Some of the most popular types include:

Style Transfer

Style transfer uses deep learning algorithms to transfer the style of one image onto another image. This technique has been used to create stunning artwork, generate realistic landscapes, and even generate new fashion designs.

Generative Adversarial Networks (GANs)

Generative Adversarial Networks are a type of AI image generator that can learn to create new images by training on a dataset of existing images. GANs work by pitting two neural networks against each other: one network generates new images, while the other network tries to distinguish between real and fake images.

Variational Autoencoders

Variational autoencoders (VAEs) are another type of AI image generator that can learn to create new images by training on a dataset of existing images. VAEs work by encoding an image into a low-dimensional representation and then decoding that representation back into an image.

Deep Dream

Deep Dream is a technique that uses deep learning algorithms to generate surreal, dream-like images. Deep Dream works by training a neural network to recognize certain patterns in images and then using that network to generate new images that emphasize those patterns.

Neural Style Transfer

Neural style transfer is a technique that uses deep learning algorithms to apply the style of one image onto another image, but it does so in a more iterative and adaptive way compared to traditional style transfer. This technique has been used to create unique art and even realistic looking photos.

Stable Diffusion

Stable Diffusion Generators work by creating an array of diffusion patterns and then blending them together to create a single unified image. The process is much faster than manually editing each individual layer, allowing you to quickly create beautiful images with minimal effort. Additionally, these generators allow you to easily control the amount of diffusion applied and tweak it until you get the exact look you want.
