Section 1.1: Image Generation from Specialized Models

Leonardo employs a model-tiered system, setting it apart from other AI image platforms that typically rely on foundational models like Stable Diffusion and DALL-E. Instead, Leonardo utilizes fine-tuned models, many of which are based on Stable Diffusion, but optimized for specific styles.

This includes a diverse array of 24 platform models tailored for various artistic styles, such as character portraits, isometric fantasy, pixel art, and photorealism. Additionally, it incorporates Stable Diffusion 1.5 and 2.1 as foundational options.

Section 1.2: Custom Model Training

One of Leonardo's standout features is the ability to train your own models. To begin, you create a dataset from either your uploaded images or selections from Leonardo’s gallery.

For instance, I assembled a dataset called "GreyZone," consisting of high-contrast and black-and-white images from royalty-free sources like Unsplash.

After setting up the dataset, I initiated the model training process, providing the necessary metadata. Essentially, this fine-tunes a new model that builds upon the Stable Diffusion base but adjusts it to the images you provided.

When generating images using this custom model, you can see how it embodies the essence of the images in the dataset.

Section 1.3: Sharing and Utilizing Community Models

Leonardo's model-centric approach allows users not only to use platform models but also to access models created by other users. This community-driven aspect enhances the platform's versatility.

I shared my GreyZone model, which is now available for others in the community to utilize.

Section 1.4: Image Editing Capabilities

Leonardo features an integrated image editor known as Canvas. To edit an image, simply select it and click 'Edit in Canvas.'

This editor allows you to re-roll, erase, or mask specific areas of your image. For example, I masked a cat's eyes and added a prompt for 'blue-eyed cat,' successfully changing the eye color.

Although still in beta, the editing feature performs exceptionally well, enabling users to make direct modifications within Leonardo.

Section 1.5: Enhanced Prompt Ideas Generation

Leonardo also offers a unique feature for generating complex prompt ideas from simple inputs. When you submit a basic prompt, the "prompt generation" feature can create more detailed suggestions.

For example, starting with the prompt 'an angry tiger,' the results are quite intriguing.
