We have entered what is known as the ‘AI boom.’ This era has welcomed hundreds of advancements in AI, helping everyday life in ways we could never expect. Developers of all kinds are hopping onto the AI train to create and train new uses for artificial intelligence in daily life. 

Part of the ‘AI boom’ is the development of AI image generators. AI image generators create images by having the intelligence train itself on a variety of materials found across the internet. Each image generator has a unique system that trains itself in different ways. 

If you want to dabble in AI image generation or get more serious about it, you will want to find the right software for your needs. Hundreds of options crop up every day and it is hard to weed through them all.

Keep reading to learn more about two of the best and see which one might be the right option for you. 

Check out this round-up of the Top AI Image Generators.

Key Takeaways

  • Leonardo AI is best for beginners who want help understanding and refining their image generations. 
  • Stable Diffusion is best for more advanced AI image generators who want no restrictions on their generations and ultimate control over the entire process. 
  • Stable Diffusion is the better of the two options in terms of control over image production and editing.

Comparison table of Leonardo AI Vs Stable Diffusion across various categories

Leonardo AI

Leonardo AI is a smaller AI image generator. It’s relatively new and the company running it wants to change how AI image generation is approached by making the process more accessible and allowing users to take control of every step. With fresh ideas, it is starting to make a name for itself. 

Key Features

  • Multiple tiers of subscriptions are available, including a free tier
  • Easy-to-navigate website
  • Customization options are endless
  • Designed for the user to get as much out of AI generation as possible
  • Available via web browser or as an app through multiple platforms

Uses

Leonardo AI had a few select goals in mind when it was being created. The first one was to make the website easy to navigate and understand. Many AI image-generation platforms can be hard to get around and extremely confusing for anyone not already used to them. 

Both the website and the app have simplistic layouts despite how much Leonardo AI has to offer. Speaking of how much it has to offer, Leonardo AI’s other goal was to be a diverse application with full control over your image generation. 

Check out this in-depth Tutorial on Leonardo AI.

It is one of the platforms with the most creative freedom at the moment. From the first step of generation, you can put in dozens of prompts to narrow down exactly what you want. From there, you can take your image and refine it.

Leonardo AI has a lot to offer and while this may be overwhelming at first, dozens of tutorials and loads of community support are there to guide you through each step of the way. 

Pros and Cons of Leonardo AI

ProsCons
Free version availableCustomer support is unresponsive and unhelpful
Total creative control with editing options available after generationTakes a lot of practice to understand the full depth of what the AI is capable of
Easy to navigate the website and grasp the basics
Accessible via web browser as well as PC and mobile app

Companies That Have Invested In Leonardo AI:

Leonardo AI is still a rather small AI image generator. It is not owned by big-name AI companies and hasn’t risen to fame as many others have. Because it is still on the rise, there are not very many companies actively using it.

However, through Leonardo AI’s investors, you can see that many companies find it worthwhile to put time and money into the program. 

  • TIRTA Ventures
  • Samsung Next
  • Blackbird Ventures
  • Side Stage Ventures
  • Smash capital

Stable Diffusion 

Stable Diffusion is an incredibly popular AI image generator and it is easy to see why. It is free to use and download, running off of your PC rather than the cloud. You gain endless options for image generation by being able to do what you want with the AI through training and editing capabilities. 

Key Features

  • Runs locally rather than through the cloud
  • Completely free
  • Intense editing capabilities
  • Requires a nice device with hefty specifications to run it properly
  • No censorship

Uses

Stable Diffusion is one of the biggest and most popular AI Image generators. It is well-loved thanks to its accuracy and attention to detail. Its editing capabilities rival that of Leonardo AI, allowing you to touch up an individual pixel.

The unique thing about Stable Diffusion is it does not run on the cloud. This means that when you download the software, it runs locally off of your computer. Cloud-based AI image generators come with many restrictions.

Without cloud interference, Stable Diffusion is limitless. 

Having it run locally also means you can train the AI how you want it. You can use your own custom models and images to make the AI create how you want it to. Because you can train it yourself, the AI becomes incredibly more accurate to your specific tastes, even before accessing the incredible editing options available.

Pros and Cons of Stable Diffusion

ProsCons
No censorship unlike many other AI image generatorsMust pay to gain access to commercial licensing 
Completely freeConfusing to understand at first
Incredible amounts of editing options are availableRequires a bulky computer to run well


Companies That Have Invested In Stable Diffusion:

There are many companies interested in the potential for Stable Diffusion. 

  • Intel Corporation
  • Sound Ventures
  • Coatue
  • Lightspeed Venture Partners
  • O’Shaughnessy Asset Management
  • Fourth Revolution Capital
  • Kadmos Capital
  • Samsung NEXT’s Q Fund

Which Is Better?

Which AI art generator is better depends entirely on what you need your AI image generation for and what you are looking to do. However, Stable Diffusion is the better of the two.

Stable Diffusion is completely free, has even more editing capabilities than Leonardo AI, and has no restrictions. If your computer can run Stable Diffusion, it is the way to go, even if it will take time to learn. 

What Are Other Good Options For AI Image Generation?

Stable Diffusion and Leonardo AI are two of the best image generators at the moment, but some other good options include Midjourney, DALL-E 3, Jasper Art, and Adobe Firefly. 

Can I Use My Images For Commercial Purposes?

Yes, for both Stable Diffusion and Leonardo AI, you can use your images for commercial purposes.

Are There Any Restrictions For What I Can Create?

For Leonardo AI, yes there are restrictions. You cannot create any content that could be considered hateful, explicit, etc. It is still working on refining these restrictions and they continue to change, however. Stable Diffusion on the other hand has no restrictions at all.
