Leonardo AI Review 2025: The Best AI Image Generator for Game and Character Art

Leonardo AI emerged from the game development world, and that origin shapes everything about how it works. While Midjourney optimises for visual impact and Firefly optimises for commercial safety, Leonardo optimises for the specific needs of digital artists who need consistent, stylistically coherent output they can actually use in production pipelines.

The Fine-Tuned Model Ecosystem

Leonardo’s most distinctive feature is its library of fine-tuned models created by both the platform team and the community. Rather than generating all images from a single general model, you select from hundreds of specialised models trained for specific styles: anime, realistic portraiture, game UI elements, sci-fi environments, architectural visualisation, fashion illustration, and dozens more. The quality difference between using the right specialised model and the wrong general one is substantial.

Character Consistency

For game developers and animators, character consistency is a production requirement — you need the same character to look the same across hundreds of images. Leonardo’s Character Reference and Image Guidance features address this directly, allowing a reference image to constrain subsequent generations. In our testing, consistency was maintained effectively for face and body proportions across diverse poses and backgrounds.
