Leonardo AI

Leonardo AI is a creative generation platform that puts image, video, 3D, and audio models behind one interface and one production API. Its library spans text-to-image systems such as FLUX, GPT Image, Ideogram, Nano Banana, Seedream, and Leonardo's own Phoenix and Lucid models, plus video models from Kling, Veo, Seedance, Wan, and others. Teams can work in the web app or send requests through the REST API, which supports asynchronous jobs, webhooks, and pay-as-you-go billing in US dollars.

Key Features

• Image generation across a large library, including FLUX, GPT Image, Ideogram, Nano Banana, Seedream, Phoenix, and Lucid.
• Video generation from text or a start image with Kling, Veo, Seedance, Wan, Hailuo, and Motion.
• 3D assets with Rodin V2 and Meshy 7, plus music, sound effects, dialogue, and speech models.
• Image guidance and ControlNet inputs, canvas inpainting, image prompts, and Elements.
• Remove Background and two Pro Upscaler modes, Precise and Creative.
• Blueprints, reusable production recipes that bundle a workflow for repeatable output.
• A REST API with async and sync generation, webhook callbacks, and a pricing calculator.

Who is it for

• Designers and illustrators who want to compare several image models in one place.
• Marketing teams producing campaign visuals, product scenes, and short clips.
• Game and product teams that need concept art or 3D assets at volume.
• Developers adding generation features to an application through an API.
• Studios moving from experimentation to a repeatable production workflow.

What can you do with Leonardo AI

• Generate images from a prompt, then refine them with inpainting or an upscale pass.
• Create short video clips from text or a starting frame using different video models.
• Produce 3D assets and audio such as music, sound effects, and dialogue.
• Remove backgrounds and enlarge images with the Precise or Creative upscaler.
• Package a working setup into a Blueprint so the same process can be rerun.
• Connect an assistant through the MCP server, or call the API from your own service.

How does Leonardo AI work

• Sign up or log in to the Leonardo web app, or open API Access for programmatic work.
• Choose a model and set parameters such as resolution, output count, and style.
• Write a prompt, and optionally add image inputs, guidance, or Elements.
• Submit the generation, then refine the output with editing, upscaling, or another model.
• For API use, create a key, send a request, and receive results by polling or webhook.
• Top up a US dollar balance when it runs low, or enable automatic top-ups.

Pricing

• Web app plans include Basic, Standard, and Pro, each with its own credit allowance and features.
• API usage is pay-as-you-go: no monthly fees, and credit is loaded into a US dollar balance.
• Balance does not expire, top-ups can be automatic, and a pricing calculator estimates each request.
• Custom pricing and per-model discounts are available for high-volume customers.
• Check the official website for current pricing and plan details.

FAQ

How is API usage billed?

API usage is charged against a prepaid US dollar balance based on the models and settings you use. There is no monthly commitment, you can top up manually or automatically, and unused balance does not expire.

Can Leonardo generate video as well as images?

Yes. The catalog includes Kling, Veo, Seedance, Wan, Hailuo, Motion, LTX, and FLUX 3 Video, accepting text prompts or start frames depending on the model.

What is a Blueprint?

A Blueprint is a reusable production recipe that bundles a workflow in the API, letting a team run a standard process repeatedly instead of rebuilding prompts and settings.

Does Leonardo offer developer tools?

Yes. There is a REST API with async and sync endpoints, webhook callbacks, official SDKs, a pricing calculator, and an MCP server for connecting an AI assistant.

Can I remove backgrounds and upscale images?

Yes. Remove Background is available as a model, and the Pro Upscaler comes in Precise and Creative variants for different enlargement needs.
