Leonardo AI: The Game Developer's Choice

Updated January 2026 | 12 min read

Leonardo AI has carved out a unique position in the AI art space by focusing on game development, character design, and consistent asset creation. Its model training features, polished interface, and generous free tier make it particularly valuable for indie developers, comic creators, and anyone needing recurring characters. This guide covers everything from basic generation to advanced training workflows.

What is Leonardo AI?

Leonardo AI is a cloud-based image generation platform launched in 2023 that differentiates itself through production-focused features. While tools like Midjourney optimize for artistic single images, Leonardo is built for creators who need multiple consistent images of the same characters, environments, and assets.

The platform combines its own trained models with the ability for users to train custom models on their own images. This means you can create a character once and then generate that exact character in unlimited poses, settings, and situations, which is exactly what game developers and comic artists need.

Key Features

Custom Model Training

Leonardo's standout feature is accessible model training. Upload 10-20 images of a character, train a model, and then generate that character consistently. This works for:

Multiple Base Models

Leonardo offers various base models optimized for different styles:

AI Canvas

A built-in editor for compositing and editing:

Realtime Generation

A fast-generation mode that produces images in near real-time as you type, great for rapid ideation and exploration.

Pricing and Tokens

Leonardo uses a token system where different operations cost different amounts:

Plan Price Tokens/Month Key Features
Free $0 150/day Basic generation, limited training
Apprentice $12/month 8,500/month Priority generation, more training
Artisan $30/month 25,000/month Private models, priority queue
Maestro $60/month 60,000/month API access, commercial priority

Token Costs

Free Tier Tip: Leonardo's free tier is one of the most generous available. 150 tokens daily is enough for meaningful work, making it excellent for experimentation before committing to a subscription.

Training Custom Models

Preparing Training Images

For best results:

Training Process

  1. Upload your training images
  2. Tag each image with descriptions
  3. Choose a base model to fine-tune
  4. Set training parameters (strength, steps)
  5. Start training (takes 15-30 minutes)
  6. Test and iterate as needed

Using Your Trained Model

Once trained, select your custom model and use a trigger word to invoke your trained concept:

"[trigger word] standing in a forest, dramatic lighting, fantasy environment"

Prompting for Leonardo

Basic Structure

Leonardo responds well to structured prompts:

"A warrior princess, silver armor, red cape, standing on a cliff overlooking a fantasy kingdom, golden hour lighting, epic composition, highly detailed, 4k"

Model-Specific Keywords

Different models respond to different style keywords:

Negative Prompts

Leonardo supports negative prompts to avoid unwanted elements:

Negative: "blurry, low quality, distorted, watermark, text"

Best Use Cases

Conclusion

Leonardo AI fills a crucial niche that other generators don't address well: production-focused image generation with character consistency. For game developers, comic creators, and anyone needing reliable, repeatable results with custom subjects, Leonardo offers capabilities that Midjourney and DALL-E simply can't match.

The generous free tier makes it easy to evaluate, and the professional features justify the subscription for serious users. While it may not produce the most artistic single images, its production workflow integration makes it indispensable for certain creative workflows.
