4 min read
Creating consistent characters with AI image tools is a challenge, especially for artists, game developers, and designers who want their characters to maintain a uniform appearance across different illustrations.
Fortunately, Leonardo AI offers an efficient solution to this problem, even for users on the free plan. In this guide, we’ll walk you through the step-by-step process of generating consistent characters using Leonardo AI.

Getting Started with Leonardo AI
Before diving into character creation, you need to sign up on the Leonardo AI platform. Here’s how:
Sign up for a free account – Use your Google, Apple, Microsoft, or email credentials to register quickly.
Access the Leonardo AI dashboard – Once logged in, you will see the public image generations from other users. Free users' images are visible in the public feed.
The Leonardo AI platform provides 150 free credits per day, which resets every night. That’s 4,500 credits per month, allowing you to create a significant number of images without needing a premium plan.
Understanding the Leonardo AI Dashboard
Once inside the Leonardo AI dashboard, you’ll find a variety of AI-generated images from other users. You can:
Explore different styles and image types.
View detailed input settings, such as prompts, models used, and additional features enabled.
Use this information to refine your own image generation process.
Free users do not have access to private generations, meaning all images created will be publicly visible. However, premium users can choose to keep their generations private.
Generating Your First Character
Open the Image Generation Tool – Click on the ‘Image Creation’ option from the left sidebar to navigate to the image generation section.
Set Up Your Preferences:
Choose a model (e.g., Lifelike Vision).
Select a preset (e.g., 3D render).
Enter a detailed prompt describing your character.
Click ‘Generate’ – Wait a few seconds for your images to appear.
Leonardo AI uses an advanced AI model to generate high-quality character images based on your input. Experimenting with different prompts can help you refine the look of your character.
Maintaining Character Consistency
Once you have generated a character you like, follow these steps to create consistent variations:
Copy the Seed Value – Click on the settings of the generated image and select ‘Copy Seed.’
Use Fixed Seed Mode – Navigate to the advanced settings, enable the ‘Fixed Seed’ option, and paste the copied seed value.
Modify the Prompt – You can adjust minor details like pose, clothing, or background while ensuring the face and key features remain the same.
Generate New Images – Click ‘Generate’ again to see variations of the same character.
How Does the Seed System Work?
The seed system in Leonardo AI ensures that your character’s facial features and overall appearance remain consistent across different prompts. When using a fixed seed, the AI references the same underlying data to generate similar images, preventing drastic changes.
Tip: In the free version, you must generate four variations at a time. However, premium users have the option to limit the output to a single variation.
Testing Character Consistency with Different Prompts
To better understand how the fixed seed system works, let’s test different scenarios:
Adding More Characters: If you modify the prompt to include additional characters, the AI may not include them due to the fixed seed constraint. It prioritizes maintaining the original character’s appearance.
Changing Character Details: Adjusting the costume or accessories works well, but major facial changes (e.g., switching gender or age) may not be reflected.
Background and Environment Changes: The AI can successfully adapt the background and overall scene while keeping the character consistent.
These tests help determine what modifications work best while maintaining character uniformity.
Dos and Don'ts of Character Consistency
✅ Dos:
Use the Fixed Seed feature to retain facial features.
Make minor adjustments to clothing, accessories, or poses.
Experiment with different prompts while keeping the core details consistent.
Save successful seed values for future reference.
❌ Don'ts:
Avoid adding multiple characters in the same prompt, as Leonardo AI will try to maintain the existing seed character only.
Changing facial structure or features won’t work if the seed is fixed.
Free users must generate four variations at a time and manually pick the best one.
Exploring Leonardo AI’s Advanced Features
Leonardo AI offers additional features to enhance character generation:
Style Strength Control: Adjusts how much the AI adheres to a particular style.
Prompt Weighting: Allows you to emphasize certain elements more than others.
By leveraging these advanced tools, you can further refine your character designs.
