Trusted by leading brands and platforms
Leonardo’s web platform is your creative design surface. Bring ideas to life using sliders and visual controls, see the output instantly, then export runnable API code with every parameter preconfigured. There’s no translation layer and no guesswork: what you see is exactly what you ship.
Skip the blank page. Blueprints give you working examples for common use cases like mood boards, bulk resizing, product mockups, upscaling and more. Run them directly on the API to test your integration, validate outputs, or build your first proof of concept, fast, confidently, and without starting from scratch.
Connect to Leonardo’s full creative stack through a single image and video generation API, supporting workflows like text-to-image, image-to-image, and image-to-video generation, all in one place. Generate everything from photorealistic images to stylized art, and power end-to-end workflows with features like LoRA training, custom presets, and upscaling. All the creative capability of Leonardo, available programmatically, without stitching together multiple tools or providers.
When I saw the potential of training my own models and having curatorial and creative control over generative AI systems, that’s when I really started to explore what was possible.

Work with our team to build custom API workflows that fit your product’s unique needs.
Built-in analytics, usage metering, and cost tracking help developers manage spend and performance intelligently. From small-scale experimentation to full-scale deployment, Leonardo offers clear pricing tiers and dedicated infrastructure options to match your workload.
Start fast, pay only for what you use, and scale when you’re ready. Leonardo’s API pricing is designed to support experimentation first, without limiting where you can go next.
Ideal if you’re moving quickly from early experiments to production
Built for running higher-volume workloads or planning long-term scale.
Please be aware that all API requests will cost API Credit. For help, please see our API documentation here
You’ll need a free Leonardo account to get started. Once you’re logged in, select API from the toolbar to set up your API access and receive $5 in free API credit to try your first generations.
Yes. Every new API account starts with $5 in free API credit, allowing you to test the API, explore features, and validate your integration before spending anything.
You can use the Leonardo API for a wide range of media generation workflows, including image generation, text-to-image, image-to-image, and image-to-video use cases. The API also supports image and video editing workflows through visual-first design and exportable production code.
Leonardo offers two API options:
Pay as you go – no commitments, pay only for what you use
Custom plans – for higher concurrency, volume discounts, and dedicated support
You can start self-serve and move to a custom plan when your usage grows.
If you require higher monthly usage, increased concurrency, or dedicated support, you can contact our team to discuss a custom API plan tailored to your needs.
Yes. Your input images are private and accessible only to you.
Yes. You can delete your input images using the Delete Init Image API endpoint.
No. Your input images are never used for training. They are only used to extract parameters that influence your specific generation request.
Yes. You can control the visibility of generated images by setting the public parameter to false when creating a generation via the API.
No. Images generated through the Leonardo API are not used for training.
You retain ownership of all inputs you provide. Leonardo assigns to you all rights, titles, and interests in the outputs generated based on your inputs, in accordance with Section 3 of our Terms of Service.
Yes. Leonardo offers API access for training custom fine-tuned models, allowing you to tailor generation to your specific use case.
Yes. Once your custom model is trained, you can generate images with it by specifying the model ID in your API request.
Default limits for usage and concurrency are published on our API Limits page. These limits can be increased with a custom plan if needed.
Yes. Higher concurrency limits are available through custom API plans. Contact our team to discuss your requirements.
Yes. Images generated using the Leonardo platform and API can be used for commercial purposes, subject to our Terms of Service.
Design visually. Export exact code. Ship with certainty. Leonardo makes production media generation accessible to every builder.
