Hands-On Testing: Putting Leonardo AI to the Test

I put Leonardo AI through its paces across several key functionalities:

1. Image Generation with Different AI Models

I focused on how Leonardo AI's specialized models handle different creative challenges.

1) Phoenix Model

Goal: To test Phoenix's core claim of unwavering prompt adherence and its ability to generate clear, accurate text within images, which is crucial for applications like advertisements, posters, and logos where precise instructions and legible text are essential.

Prompt: A photorealistic, award-winning advertisement poster. In the top center, the bold, capitalized headline text "A TASTE OF TOMORROW". Below the headline, a sleek, minimalist glass bottle of juice is the main subject. The juice is a vibrant green color. On the bottle's label, the brand name "Phoenix Elixir" is written in an elegant, clean font. At the very bottom of the poster, in smaller text, is the slogan: "Freshly Squeezed Future." The background is a soft, out-of-focus image of a sun-drenched orchard.

What I Found: Phoenix performed exceptionally well. It generated all text correctly and followed the specified layout perfectly, a notable feat for AI image generators.

2) Flux Kontext Model

Goal: To evaluate Flux Kontext's advertised strength in making precise edits to specific elements within an existing image while seamlessly blending those changes and preserving all other details. This is a powerful capability for iterative design and refining visuals without starting from scratch.

Prompt: change the color of her hair and her clothes from gold to pink. Turn the background dreamy pink. Keep the rest detail unchanged.

What I Found: Flux Kontext delivered an amazing job. It precisely altered requested elements, seamlessly blending changes while perfectly retaining and integrating untouched details.

2. Image Generation with Different AI Preset

Leonardo's presets offer quick stylistic changes. I used a single core prompt and applied it to three different presets to see their unique interpretations.

Prompt: A young woman with sparkling eyes is blowing colorful bubbles, surrounded by soft sunlight and flowers

1) Portrait Perfect Preset

Goal: To assess its focus on generating flattering and detailed human figures, evaluating its ability to render realistic and aesthetically pleasing portraits within a broader scene.

What I Found: Results often looked strange, with poor semantic understanding. The woman appeared surrounded by bubbles, not blowing them, and images frequently contained distorted details like misshapen fingers and eyes.

2) Stock Photography Preset

Goal: To evaluate its ability to generate clean, commercially viable images suitable for common stock photo needs, often characterized by clear subjects, good lighting, and broad appeal.

What I Found: Similar to Portrait Perfect, this preset often produced weird compositions, incorrect gestures, messy details, and distorted facial features, suggesting struggles with complex scene interpretation.

3) Anime Preset

Goal: To see how effectively this preset translates a general scene into a characteristic anime style, observing its use of typical visual tropes, color palettes, and character aesthetics.

What I Found: While overall color was often good, detail quality was messy. Figures frequently had distorted fingers, and the action (blowing bubbles) was sometimes misinterpreted (e.g., eating a lollipop).

3. Real-Time Canva

This is a feature I've really come to appreciate after using it. It lets you sketch out an idea directly within the interface, and then watch the AI generate results based on your drawing in real-time. What I realized quickly was how incredibly handy it is for brainstorming concepts, exploring different styles, or quickly refining a rough, hand-drawn idea. It's a highly interactive and creative tool.

4. Flow State

Flow State is designed for rapid iteration, continuously generating a stream of images from a single prompt. The idea is to allow you to quickly explore variations and refine your vision without manually hitting 'generate' each time.

My key takeaway here, however, was the credit consumption. It keeps generating automatically until you manually stop it by clicking on an image you like. Each generation costs one credit. I quickly learned that if you let it run for a while, those credits can add up surprisingly fast. You really need to be mindful and stop the process once you see something promising to avoid burning through your tokens.

5. Universal Upscaler

I put this feature to the test with a couple of different images to see how it handled enhancing existing artwork. One key aspect of this upscaler is its 'Creative Strength' setting, which ranges up to 10. This setting essentially controls how much the AI is allowed to invent or alter details during the upscaling process.

1) Upscale with 5/10 Creative Strength

The process felt a bit longer than expected at this level, but the results were quite impressive, I thought. I noticed it added significant detail, particularly in areas like finger joints and subtle facial shadows. Overall, I was quite satisfied with the outcome at this creative strength after seeing the final image.

2) Upscale with 0/10 Creative Strength

My goal here was a true 1:1 upscale – preserving the original details without adding anything new. Thus, I set the creative strength to 0.

Unfortunately, what I found was this didn't work as intended. Instead of a faithful reproduction, the outcome looked noticeably altered. I observed details lost, like freckles on the face and the fine lower eyelashes. What's more, the lips in the upscaled image looked quite strange, even a little unsettling.

This experience really highlighted for me a common challenge with some AI upscalers – they struggle to maintain the original image's integrity when you want a simple, non-creative enlargement. It made me appreciate tools like VideoProc Converter AI, which I've found excels at upscaling and enhancing media while genuinely preserving those crucial original details you want to keep.

What Others Are Saying: User Feedback on Leonardo AI

Moving beyond my own testing, it's always insightful to see what the wider user base thinks. Looking at platforms like Trustpilot, Leonardo AI holds a respectable 4.4 out of 5 stars based on numerous reviews, reflecting a generally positive sentiment among users.

Digging into the reviews, a consistent theme emerges: users are largely satisfied with the customer service and support team. This seems to be a significant strength for the platform, offering reassurance when issues arise. The most frequent criticism seems to revolve around image quality and consistency, particularly when compared to some competitors on certain types of prompts, and the speed at which credits are consumed.
