Table of Contents

AI image generators have become very popular in the past few years. They are now a common feature on social media, news sites, and magazines. AI-generated images now impact our daily lives. We can’t ignore it. Their accessibility and growing sophistication have drawn attention. They let users create stunning content with ease. Whether you want to explore AI art for personal use or improve your business with AI, there are apps to help you. They offer various options to get you started.

Since Google Deep Dream’s launch in 2015, I’ve followed AI image generators. These tools, once limited to computer science labs, have advanced. They are now more accessible and powerful than ever. I find it fascinating to see our progress. I’m excited by the ongoing innovation in this field.

I’ll skip the complex debates on art, AI’s impact on artists, and copyright issues with the training data. Instead, I will focus on the abilities of AI image generators. They can create captivating visuals from a variety of text prompts. These tools have advanced greatly. They now offer users a wide range of creative options.

Spending a few hours on a text-to-image AI app is worth it. It will give you an appreciation for the technology behind it. Whether you’re a fan or not, AI-generated visuals are now common. Their presence will only grow in the future.

What is AI image generation?

AI image generators use trained neural networks to create images from text. These tools excel at blending different styles and ideas. They create visually stunning and relevant images. This innovation is powered by Generative AI. It’s a branch of AI that creates content.

Developers create AI image generators using vast datasets of images. This allows the algorithms to learn various features and traits during training. This lets them create new images that mimic the original data’s style and content. They produce unique visuals based on their learned patterns.

AI image generators come in many forms, each offering distinct capabilities. Neural style transfer applies one image’s style to another. GANs use two neural networks to create realistic images from training data. Diffusion models generate images. They do this by turning random noise into structured visuals. They mimic the diffusion of particles.

How AI image generators work.

AI image generators use advanced deep learning models called neural networks. They create visuals from text prompts. These generators learn from vast datasets of text-image pairs. They learn to match descriptions with visuals. Then, they can create new images based on the input they receive.

Modern AI generators convert text into images in two steps. Each uses a specific type of generative model. This method lets them turn written descriptions into visuals with great success.

  • a transformer-based model for encoding text, and
  • a diffusion model for producing visuals.

Google developed Transformers to improve NLP. Now, they drive Google Search, Translate, and AI models like ChatGPT and Bard. They also boost speech recognition and text autocompletion. They now do image recognition and sound generation, too.

In AI image generation, transformers use self-attention to analyze a prompt. It finds how different parts of the sentence relate. This process creates a digital representation of the data and its connections. They call it a vector.

Researchers base diffusion models on the physics of particle diffusion. It is where particles move from concentrated to dispersed states. In training, the model adds noise to images until it distorts them. It then reverses the process. It learns to reconstruct the original images from the noise.

In text-to-image models, diffusion processes use the vector’s information to create an image. It should represent the concepts in the prompt.

How AI image generators work: an introduction to the technology behind them.

This section explores the process behind the best AI image generators. This will focus on how these models train to produce images.

Text understanding using NLP

AI image generators interpret text prompts by converting them into numbers. This makes the data readable for machines. This process uses Natural Language Processing (NLP) models. One is the Contrastive Language-Image Pretraining (CLIP) model. It is in diffusion models like DALL-E.

This process converts the input text into high-dimensional vectors. They will capture its meaning and context. Each coordinate will represent a specific attribute of the text.

For example, a user enters the prompt “a red apple on a tree.” The NLP model converts the text into a number. It captures the key elements—”red,” “apple,” and “tree”—and their relationships. This numerical encoding guides the AI image generator in creating the final image.

This map guides the AI in creating the final image. It dictates what elements to include and how they should interact. The AI generates a red apple on the tree based on the prompt.

This quick change of text to numbers, then to images, lets AI image generators render text prompts.

Generative Adversarial Networks (GANs)

Generative Adversarial Networks, or GANs, are machine learning algorithms. They use two rival neural networks: the generator and the discriminator. The “adversarial” aspect comes from their rivalry. They challenge each other in a process like a zero-sum game.

In 2014, Ian Goodfellow and his team at the University of Montreal introduced GANs. They did so in their paper, “Generative Adversarial Networks.” This innovation drew attention. It led to research and made GANs a cornerstone of generative AI.

GANs have two main components called sub-models. They form the architecture of GANs.

  • The generator neural network handles generating fake samples. It takes a random input vector—a list of unknown variables. It uses this to create fake input data.
  • The discriminator neural network functions as a binary classifier. It takes a sample as input and determines whether it is real or produced by the generator.

For more insights, check our video. It explains how computer vision apps work.

The adversarial aspect of GANs is rooted in game theory. The generator aims to create fake samples that look like real data. The discriminator tries to tell apart real and fake samples. This competition drives both networks to keep improving their performance.

If the discriminator correctly identifies a sample, it wins. This prompts the generator to improve. If the generator deceives the discriminator, it wins. This updates the discriminator.

Success is when the generator creates a sample so good that it fools the discriminator and is hard for humans to tell apart. The discriminator uses labeled data to assess the generated images. It is a reference for what real images should look like.

During training, the training process gives the discriminator real and generated images. They label the real images as “real.” The generated ones are “fake.” This labeled data is the “ground truth.” It creates a feedback loop. This helps the discriminator better tell real from fake images. At the same time, the generator learns from fooling the discriminator. It then improves its output. As the discriminator becomes more skilled, the process continues in an ongoing cycle.

Diffusion Models

Diffusion models are generative models in machine learning. They create new data, like images and sounds, by mimicking their training data. They work by adding noise to the data. Then, they learn to reverse the process. This produces new, similar data.

Diffusion models are like expert chefs. They recreate dishes by understanding the ingredients and flavors of what they’ve tasted. These models are like a chef who can replicate a dish after tasting it. They can generate data, such as images, that closely resemble their training data.

Forward diffusion (adding ingredients to a basic dish). At this stage, the model starts with an image. It then adds random noise through a series of steps using a Markov chain. Each step alters the data based on its previous state. The added noise is Gaussian, a common type of random noise.

Training (Understanding the tastes). In this phase, the model learns how the added noise changes the data during forward diffusion. It maps the transition from the original to the noisy version. The goal is to master this process so much that it can reverse the steps. It must estimate the differences between the original data and the noise at each stage. Training focuses on perfecting this reverse process.

Reverse diffusion (recreating the dish). After training, the model reverses the process. It removes the noise from the data, retracing the steps in the opposite direction. This allows the model to generate new data that has a strong resemblance to the original.

Generating new data (making a new dish). The model then uses what it learned to generate new data. It starts with random noise. A text prompt guides the transformation of the noise into a clear image.

The text prompt acts as a guide, directing the model on what the final image should resemble. The model uses reverse diffusion steps. It slowly shapes the noise into an image that matches the prompt. It does this by minimizing the difference between the image and the text. Diffusion models create realistic data by adding and then reversing noise. This process generates images, sounds, and more.

Neural Style Transfer (NST)

Neural Style Transfer (NST) is a deep learning technique. It merges the content of one image with the style of another. This creates a new, unique artwork.

Neural Style Transfer uses a pretrained network to analyze visuals. It extracts the style from one image and applies it to another. This creates a new image that blends elements from both.

The process involves three core images.

  • Content image — This is the image whose content you wish to retain.
  • Style image — This one provides the artistic style you want to impose on the content image.
  • Generated image —At first, this could be a random image or a copy of the content image. The artist modifies this image over time. He wants to blend the content of the content image with the style of the style image. It is the only variable that the algorithm actually changes during the process

Neural networks in NST consist of layers of neurons that detect different features. Early layers find edges and colors. Deeper layers combine these to recognize textures and shapes. NST uses these layers to blend content with style. This creates a unique image.

Content loss measures how much the generated image differs from the original. NST uses several neural network layers to preserve the content. They capture key elements and ensure the generated image is like the original.

Style loss focuses on the textures, colors, and patterns in an image. It measures the difference between the styles of the two images. NST works to align these textures and patterns across various layers in both images.

Total loss in NST is the combined measure of content loss and style loss. Balancing these two is key, as focusing too much on one can compromise the other. NST lets you adjust the balance between content and style. An algorithm then tweaks the pixels to cut the total loss.

As optimization improves, the image will mix the content and style of various sources. This will happen over time. It results in a striking blend that resembles art.

GANs, NST, and diffusion models are popular AI image generation tools. As researchers push the limits, new techniques are emerging in this fast-changing field.

What makes the best AI image generator?

AI image generators are very popular now. They’ve improved a lot in the past two years. Earlier versions, while impressive to researchers, failed to meet expectations. Even the original DALL·E, launched in 2021, was seen more as a novelty than a game-changer at the time.

With text-to-image generators now more established, competition has intensified. This has led to much more realistic results. To identify the best AI art generators, I applied strict criteria to check them:

  • I focused on apps that generate AI images from text prompts. AI portrait tools from uploaded photos can be fun. But, they weren’t the general-purpose image generators I was testing.
  • I focused on the AI image generators themselves, not tools built on top of them. NightCafe is popular. It has access to models like FLUX, Stable Diffusion, and DALL·E 3. But it mainly serves as a platform for these existing models, not a standalone generator. So it doesn’t meet my criteria for this list.

I also checked the user-friendliness of each AI image generator. I looked at its control and customization options, like image upscaling. I reviewed its pricing model and focused on the quality of the results, which was crucial. Today’s best AI image generators are less likely to create strange, unrealistic visuals.

I’ve written about text-to-image generators since DALL·E’s debut. I’ve covered photography and art for over a decade. So, I’m well-versed in how these tools work and their strengths, weaknesses, and quirks. I compared several AI image generators using the same prompts for the first time. The results were intriguing. Each app on this list offers unique benefits worth exploring.

Before we begin, many of these tools are still in beta. They will likely remain so for some time. AI image generators improve daily. But, they still have room to grow. They can’t yet deliver high-quality results and integrate into commercial workflows.

The best AI image generator for ease of use

DALL·E 3

The best AI image generator for ease of use DALL·E 3

DALL·E 3 pros:

  • Incredibly easy to use
  • Included with ChatGPT Plus, so you get a lot of AI for your money

DALL·E 3 cons:

  • ChatGPT controls can be hit and miss
  • $20/month is pricey if you don’t want GPT with it

DALL·E 3 is one of the most recognized names in AI image generation, and for good reason. Its predecessor, DALL·E 2, was the first popular AI image generator. It could create captivating, viral-worthy visuals.

DALL·E 3 is a major upgrade from DALL·E 2, delivering more realistic, consistent, and engaging results. While OpenAI had seemed to lag behind competitors in AI image generation, DALL·E 3 has put it back in the lead. It is accessible via ChatGPT, Microsoft Bing’s AI Copilot, and other services using its API.

DALL·E 3 stands out for its ease of use. Describe what you want to ChatGPT or Bing. Within moments, you’ll get two to four AI-generated variations. It uses GPT-4’s language skills to refine your prompts. It delivers unique results, with an option to request more at any time.

OpenAI lets free ChatGPT users create two daily images with DALL·E 3. Microsoft offers more flexibility at no cost. Although I found Copilot a bit less intuitive, it is still a great deal. The best option, yet, is ChatGPT Plus. It lets you generate unlimited images within the platform’s messaging limits.

DALL·E pricing: DALL·E 3 is included as part of ChatGPT Plus at $20/month and available for free through Microsoft Copilot; API pricing is more complex but starts from $0.016/image.

The AI image generator with the best results

Midjourney

The AI image generator with the best results Midjourney

Midjourney pros:

  • Consistently produces the best looking AI-generated images
  • The community is a great way to get inspiration

Midjourney cons:

  • Images you generate are public by default
  • Free trials are currently suspended

Midjourney is the best of all the image generators I’ve tried. Its images are more cohesive. They have richer textures and colors. So, they are more appealing. With few prompts, people and objects look more lifelike than in other AI generators. It’s no surprise that Midjourney was the first AI image generator to win an art competition.

The best part is that Midjourney now has a web app. So, you no longer need to access it through Discord, though that’s still an option. The web app lacks some advanced features. These include blending images and maintaining details across generations. But it has a powerful editor. It lets you control the final result.
Midjourney does have its quirks. Every image you create is posted publicly on its Explore page and visible on your profile by default. This adds a nice community element. But, if you’re using Midjourney for business, the lack of privacy could be a drawback.

If you’re feeling a bit overwhelmed, don’t worry. Midjourney’s help docs are excellent. They guide you through the setup for the web app and Discord. They explain how to use its features. This includes choosing model versions, upscaling, and personalizing with character references. When you grasp the options, the results become impressive.

Midjourney has suspended free trials due to high demand. They return for a few days from time to time. If you miss a trial, the Basic Plan costs $10 a month. It offers 3.3 hours of GPU time, or about 200 images, with an option to buy more. You can use your images for commercial purposes.

Midjourney pricing: From $10/month for the Basic Plan that allows you to generate ~200 images/month and provides commercial usage rights.

Best AI image generator for accurate text Ideogram

Ideogram pros:

  • Great looking AI-generated images—and the most accurate text of any app
  • There’s a free plan

Ideogram cons:

  • Images you generate are public by default

Most AI image generators struggle to render text. The diffusion process limits them. Ideogram has solved this with its 2.0 algorithm. It can add text to generated images with precision.

What makes Ideogram even more impressive is that it is one of the best image generators. Its web app is intuitive. It has useful features, like an image editor and the ability to use existing images as a starting point. In my experience, only Midjourney outperformed it. But Midjourney has some limits due to its reliance on
Discord.

Ideogram offers a free plan with 10 credits per day. You will wait a bit for each generation. You will only have basic features. Still, it’s a great way to explore a top AI image generator.

Ideogram pricing: Limited free plan; from $8/month for full-resolution download and 400 monthly priority credits.

Best AI image generator for customization and control

Stable Diffusion

Best AI image generator for customization and control Stable Diffusion

Stable Diffusion pros:

  • Widely available across AI art generator platforms
  • Affordable, customizable, and super powerful with generally great results

Stable Diffusion cons:

  • The company behind it is collapsing
  • There’s no one easy option for using it

Unlike DALL·E and Midjourney, Stable Diffusion is open source. Anyone with technical skills can download and run it on their local machine. It also enables users to train and fine-tune the model for specific purposes. Many AI services that generate artistic portraits, historical images, and architectural renders rely on Stable Diffusion for this flexibility.

Yet, open source can cause instability. This happened with Stability.ai, the maker of Stable Diffusion. Now, the company is on the brink of collapse. It has faced criticism for its latest model and its licensing terms. Most of the research team has left to start a new venture, which I’ll discuss next.

Stable Diffusion finds itself in an uncertain position. Its current versions are among the best available. Many fine-tuned models enhance specific applications. But, its future is unclear due to recent developments.

Stable Diffusion Pricing: Depends on the platform, but many offer free credits so you can try them out.

Best Stable Diffusion alternative

FLUX.1

Best Stable Diffusion alternative FLUX.1

FLUX.1 pros:

  • From the team behind Stable Diffusion—but without the drama
  • Powerful and open

FLUX.1 cons:

  • New and not as widely available as Stable Diffusion

As Stability.ai began to falter, much of the team left to create Black Forest Labs. It has since launched its first text-to-image models, FLUX.1.

In my experience, FLUX.1 performs on par with Stable Diffusion. It has not yet received widespread support. But, I expect it to gain popularity as more AI artists fine-tune it for specialized models.

For advanced AI image generation, try FLUX.1 over Stable Diffusion. FLUX.1 Schnell is under the open Apache 2.0 license. The larger FLUX.1 is free for non-commercial use.

Like Stable Diffusion, the easiest way to try FLUX.1 is on AI art sites like NightCafe, Tensor.Art, or Civitai. You can sign up for free, test it out, and compare it with other models. Yet, be aware that not all content on these sites is safe for work.

FLUX.1 Pricing: Depends on the platform, but many offer free credits so you can try them out.

Best AI Image Generator for Blending AI-Generated Images with Photos

Adobe Firefly

Best AI Image Generator for Blending AI-Generated Images with Photos Adobe Firefly

Adobe Firefly pros:

  • Integrates well with Adobe’s apps, especially Photoshop
  • Powerful when it’s matching an image

Adobe Firefly cons:

  • Not the best as a pure text-to-image model

Adobe has been adding AI to its apps for over 15 years. So, it’s no surprise that Firefly, its text-to-image generator, is among the most powerful. This is especially true when it’s integrated with other tools. You can test Firefly for free online or in Adobe Express. But, it shines in the latest version of Photoshop.

Firefly does more than generate images from text. It can create text effects, like turning “TOAST” into letters made of toast. It can recolor vector art and add AI-generated elements to existing images. While you can try these features in the web app, it excels at adding AI elements to your images.

As a text-to-image generator, Firefly’s results can be inconsistent. For some prompts, it competes with DALL·E and Midjourney, but for others, its output seems unclear. Yet, its seamless integration with Photoshop, the industry-standard image editor, sets it apart.

Adobe Firefly pricing: Free for 25 credits/month; from $4.99 for 100 credits/month; Photoshop is available from $19.99/month as part of the Creative Cloud Photography Plan, which comes with 500 generative credits.

Best AI Image Generator for Commercially Usable Images

Generative AI by Getty Images

Best AI Image Generator for Commercially Usable Images Generative AI by Getty Images

Getty pros:

  • Surprisingly effective at generating stock-like photos.
  • Getty indemnifies you from any legal claims resulting from your use of the images it generates.

Getty cons:

  • Less creative and fun to use.
  • Can’t compete with Midjourney, DALL·E 3, or Stable Diffusion in terms of overall quality.

AI image generators are controversial, especially with the unclear legal landscape. The U.S. Copyright Office has ruled that no one can copyright AI-generated images. Others can use your creations without consequences. For businesses, avoiding generative AI might be the safest choice. If you still want to use them, try Getty Images. It ensures its AI generator is free from legal issues.

Getty Images’ Generative AI, available via iStock, performs well. It excels at creating stock-style photos. In my tests with prompts like, “woman laughing alone with salad,” the results were almost identical to real stock photos.

For prompts like “a Canadian man riding a moose through a maple forest,” the results were less polished. This includes anything requiring specific art styles. This is likely due to the training data. Generative AI uses NVIDIA Picasso and relies mainly on Getty’s stock images. Getty ensures the process was ethical and pays artists whose work trained the model.

While this approach is commendable, it limits what you can generate. Generative AI avoids using anything with real people, trademarks, or IP issues. It wouldn’t even generate a painting in the style of Vermeer, despite his passing in 1675. This makes Getty’s tool less flexible. But, it’s more practical for businesses worried about legal compliance.

Generative AI by Getty pricing: Available as Generative AI by iStock for $14.99 for 100 AI generations
