Dimensions summary
This listing offers one contract-based option: Leonardo.ai API Custom, priced in units. You commit to a set quantity of API units under a negotiated agreement rather than paying per generation as you go. This custom option suits higher-volume workloads and long-term use. It supports custom concurrency limits, model-based discounts, and dedicated support for production deployments. Pricing scales with the number of units you commit to. All API requests draw down against your purchased units.
Top-of-mind questions for buyers
A unit maps to API Credit consumed by generation requests. Every API call draws down credit, including text-to-image, image-to-image, and image-to-video jobs. Model training and upscaling also consume credit. The credit cost varies by the type and settings of each generation request.
Yes. The custom option supports negotiated concurrent generation limits, meaning more generations can run at the same time. It also includes model-based discounts and dedicated support for production deployments. You arrange these terms with the vendor to match your workload.
You can run text-to-image, image-to-image, and image-to-video generation through a single API. Units also cover training custom fine-tuned models, generating with those models by ID, custom presets, and upscaling. Each of these workflows draws down credit when you call the API.

What do you dislike about the product?
Advanced tools, like video generation, drain credits very quickly. It also occasionally struggles with fine details, such as hands and getting text exactly right.
What problems is the product solving and how is that benefiting you?
It helps us generate images with commercial rights for our internal tools and platforms. With model training, we can also create customised images tailored to our product use case and aligned with our customers’ behaviour.

Leonardo AI: Fast, High-Quality Image Generation with Excellent Prompt Handling
Reviewed on Jan 21, 2026
Review provided by G2
What do you like best about the product?
Some of the features I like in Leonardo AI are its high-quality image generation, especially the strong, realistic styles, along with excellent prompt handling. Generation is also fast while still maintaining good output quality. I mainly use it to create YouTube thumbnails and cinematic visuals, and it fits that workflow well.
What do you dislike about the product?
I don’t like it, mainly because the daily credits are limited, which restricts how often I can generate images and videos. On top of that, most of the more advanced features and models are locked behind paid plans, so it feels like I can’t really use the tool as much as I’d like without upgrading.
What problems is the product solving and how is that benefiting you?
Thanks to its fast visual generation, it saves me a lot of time compared with manually designing every element for my Youtube channel.

Image understanding ability should be improved. Basically, humans are weak in prompt generation, so if Leonardo makes clarification on what a human needs, then we can see improved Leonardo.
