Leonardo AI Review 2025: Best Free AI Image Generator?

Leonardo AI offers something rare in the AI image generation space: a genuinely useful free tier. With 150 daily tokens, quality that competes with paid alternatives, and an interface that doesn't require a PhD in prompt engineering, it's become the go-to recommendation for anyone testing AI image generation.

But is the free tier enough? When should you upgrade? And how does Leonardo actually compare to Midjourney and DALL-E 3 when you push it? We spent 30 days testing Leonardo AI extensively - free tier first, then paid - to answer these questions definitively.

Bottom line upfront: Leonardo AI is the best free AI image generator available in 2025, and the paid plans offer excellent value. It won't match Midjourney's artistic peak, but for most users, it's more than enough.

Quick Verdict

Best for: Hobbyists, beginners, content creators with moderate needs, anyone testing AI image generation before committing budget.

Not ideal for: Professional artists needing maximum quality, high-volume commercial production, users requiring consistent artistic style.

What is Leonardo AI?

Leonardo AI launched in late 2022 and has grown into one of the most popular AI image generators, primarily because of its generous free tier and approachable interface. Unlike Midjourney (Discord-based, now web) or Stable Diffusion (technical setup required), Leonardo AI offers a polished web application that works immediately.

The platform combines multiple AI models - both Leonardo's proprietary models and fine-tuned versions of Stable Diffusion - accessible through a single, unified interface. This means you can switch between photorealistic, anime, 3D, and illustrative styles without changing tools or learning new workflows.

Core Features

• Image Generation: Text-to-image with multiple model options
• Image-to-Image: Transform existing images with AI
• AI Canvas: Photoshop-like editing with AI capabilities
• Motion: Add animation to static images
• Realtime Generation: Live preview as you type
• Model Training: Create custom models (paid)
• Community Models: Access user-created fine-tuned models
• Upscaling: Enhance resolution up to 4x

Leonardo AI Pricing in 2025

Annual billing saves 20% - Apprentice drops to $8/mo, Artisan to $19.20/mo, Maestro to $38.40/mo.

Understanding Tokens

Token costs vary by model and settings:

• Standard generation: 4-8 tokens per image
• High-resolution: 12-20 tokens per image
• Alchemy (enhanced): 15-30 tokens per image
• Motion: 25+ tokens per animation

With 150 free daily tokens, you can realistically generate 30-50 standard images or 10-15 high-quality images per day. That's substantial for casual use.

Free Tier Deep Dive: Is 150 Tokens Enough?

We tested Leonardo AI's free tier exclusively for two weeks. Here's exactly what you can and cannot do:

What Works Great on Free

Daily creative projects: 150 tokens refreshes every 24 hours. For personal projects, social media content, or learning AI image generation, this is plenty. We generated approximately 40 images daily without running out.

Learning prompts: The free tier includes all the basic models and features. You can experiment extensively without financial commitment.

Portfolio building: If you're exploring AI art for a portfolio or personal brand, free tier lets you create substantial work over time.

Blog and content creation: One or two hero images per day? Easy. A week of social media posts? Absolutely doable.

Where Free Falls Short

Commercial production: Client work requiring multiple revisions, variations, and high-resolution outputs will burn through 150 tokens quickly. Expect to upgrade within days.

High-volume needs: If you need 100+ images daily, free tier won't cover it. Simple math.

Priority access: Free tier users wait in queue during peak times. Generation can take 30-60 seconds instead of the usual 10-15 seconds.

Advanced features: Model training, API access, and some premium models require paid plans.

Our Free Tier Verdict

For 80% of users exploring AI image generation, the free tier is genuinely sufficient. Leonardo isn't playing the "free trial that's useless" game - they're offering real value to attract users who'll eventually upgrade.

Image Quality: How Good Is Leonardo AI Really?

Quality is the critical question. Nobody cares about free if the images look bad. So we ran Leonardo AI through our standard 50-prompt test suite and compared results to Midjourney and DALL-E 3.

Test Results by Category

Key Observations

Leonardo excels at anime and illustration. The specialized anime models (DreamShaper, Anime Pastel Dream) produce results that rival or exceed Midjourney for this specific style. If anime or stylized illustration is your focus, Leonardo is arguably the best choice regardless of price.

Photorealism is surprisingly strong. Leonardo's Phoenix model handles realistic portraits and scenes competently. Not quite Midjourney's editorial quality, but entirely usable for most purposes. We'd rate it 85% of Midjourney's photorealistic capability.

Artistic interpretation is where Leonardo lags. Midjourney has an intangible "magic" - images feel more artistically composed, lighting is more dramatic, colors are more harmonious. Leonardo produces good images; Midjourney produces beautiful ones.

Text rendering is weak but improving. Like most non-DALL-E generators, Leonardo struggles with text. Version 3 (Phoenix) handles simple text better than before, but don't expect reliable results for logos or signage.

Model Comparison Within Leonardo

Leonardo offers multiple models, each with distinct strengths:

The right model makes a significant difference. Phoenix for realism, anime models for stylized work, Kino for drama.

Interface and User Experience

Leonardo AI's interface deserves praise. It's the most beginner-friendly of any serious AI image generator.

What Works Well

Clean, modern design: No Discord complexity, no terminal commands. Just a web app that looks like it was designed in 2025, not 2019.

Preset models with previews: Each model shows example outputs, so you know what style you're getting before you generate. Eliminates guesswork.

Prompt suggestions: Start typing and Leonardo suggests completions. Helpful for learning effective prompts.

History and organization: All generations are saved with full prompt history. Easy to revisit and iterate on past work.

Real-time preview: The Realtime Generation feature shows a rough preview as you type, helping you refine prompts before spending tokens.

What Could Improve

Token visibility: It's not always clear how many tokens a specific generation will cost until you click generate. More upfront transparency would help.

Mobile experience: The web app works on mobile but feels cramped. A dedicated mobile app would be welcome.

Batch operations: No way to run multiple prompts simultaneously. Each generation is individual.

AI Canvas: Leonardo's Secret Weapon

The AI Canvas feature deserves special attention. It's essentially a simplified Photoshop with AI generation built in.

What Canvas Does

• Inpainting: Select an area, describe what you want, and AI fills it in
• Outpainting: Extend images beyond their original boundaries
• Object removal: Select and delete unwanted elements
• Style transfer: Apply artistic styles to specific regions
• Composition: Combine multiple generated elements into one scene

Why Canvas Matters

Most AI image generators are one-shot: you prompt, you get an image, you're done. Canvas enables iterative creation - start with a base image, refine specific areas, add elements, adjust compositions. This workflow is closer to how professional artists actually work.

We used Canvas to create a fantasy landscape: generated the base scene, then inpainted a castle on the hill, extended the sky for more drama, and removed an unwanted rock formation. Total time: 15 minutes. Doing this with regeneration alone would have taken hours of luck.

Canvas Limitations

• Uses more tokens than standard generation
• Learning curve for effective masking
• Some operations feel slower than they should
• Not as powerful as Photoshop + Stable Diffusion workflows

High-volume commercial operations: Token limits, even on paid plans, may not match the throughput needed for large-scale production.

Tips for Getting the Most from Leonardo AI

Model Selection Matters

Don't just use the default. Each model has distinct strengths:

• Portraits: Leonardo Phoenix
• Landscapes: Kino XL
• Anime: Anime Pastel Dream or DreamShaper
• 3D/Game assets: 3D Animation Style
• General creativity: Leonardo Diffusion XL

Prompt Structure

Leonardo responds well to structured prompts:

[Subject], [Style], [Lighting], [Mood], [Quality modifiers]

Example: "A cyberpunk street market, neon lighting, rain reflections, moody atmosphere, highly detailed, 8k quality"

Use Negative Prompts

Leonardo supports negative prompts - what you don't want. Common exclusions:

• "blurry, low quality, distorted"
• "extra limbs, deformed hands"
• "text, watermark, signature"

Leverage the Community

Leonardo's community gallery shows prompts for every public image. Find something you like? See exactly how it was made. This learning resource is underutilized.

Canvas for Complex Work

For anything beyond single-scene images, use Canvas. The ability to iterate and refine beats regenerating from scratch every time.
