Leonardo.Ai offers an AI image generator that takes written text prompts or existing images as input and produces high-quality still images in a wide range of artistic styles, from photorealism to anime to concept art. The tool is available to all users on a free tier with daily tokens, and with expanded capabilities on paid plans.

The platform uses diffusion-based generative AI models — including its own in-house foundational models Phoenix (launched June 2024) and Lucid Origin (launched August 2025), as well as third-party models like Flux and Ideogram — to convert text prompts or image references into new images. Users can select from a library of 30+ fine-tuned models optimized for specific styles such as cinematic, photorealistic, anime, or game assets. The system supports text-to-image and image-to-image workflows, with additional controls for aspect ratio, guidance strength, and style reference.
