The 3D Animation model produced usable game assets but required post-processing for production pipelines.

Resolution Support: All models generate at resolutions up to 1024×1024 pixels by default, with paid plans offering upscaling to 3072×3072 pixels via the Smooth Upscale tool.

2. AI Canvas: Professional Editing Workspace

Rating: Ease of Use ★★★☆☆ | Functionality ★★★★★ | Speed ★★★★☆ | Flexibility ★★★★★

AI Canvas provides layer-based editing capabilities that rival traditional design software:

• Inpainting/Outpainting: Add or remove elements from existing images
• Object manipulation: Adjust positions, scale, and rotations post-generation
• Background replacement: Swap environments while maintaining lighting consistency
• Smart erasing: Remove unwanted elements with AI-powered fill
• Layer compositing: Combine multiple generated elements into cohesive scenes

Testing Results: AI Canvas excels at minor corrections and iterative refinement. However, editing small, intricate details proved unintuitive even with tutorial guidance. The tool works best for broad adjustments (changing backgrounds, removing large objects) rather than precision work (facial feature refinement, texture detail editing).

Learning Curve: Moderate. Expect 2-3 hours to become comfortable with the interface.

3. Realtime Canvas: Sketch-to-Image Generation

Rating: Ease of Use ★★★★☆ | Functionality ★★★☆☆ | Speed ★★★☆☆ | Flexibility ★★★☆☆

Leonardo AI extends beyond static images with experimental features:

• Motion Video: Animate static images with camera movements and subtle motion
• 3D Texture Generation: Create PBR materials (albedo, normal, roughness maps) for 3D models
• OBJ File Support: Apply AI-generated textures directly to uploaded 3D models

Testing Results: Motion generation is limited to subtle animations (2-4 seconds) and cannot create complex character animations. The 3D texture tool produced usable results for architectural visualizations but lacked the refinement needed for close-up product shots. These features feel like beta releases rather than production-ready tools.

5. Transparent PNG Generator

Rating: Ease of Use ★★★★★ | Functionality ★★★★★ | Speed ★★★★★ | Flexibility ★★★★☆

Automatically removes backgrounds from generated images, creating transparent PNGs suitable for:

• Logo design and branding
• Product photography composites
• Marketing materials and presentations
• UI/UX element creation

Testing Results: The background removal tool worked flawlessly on simple subjects (90%+ success rate) but struggled with complex scenes involving hair, transparent objects, or intricate edges (65% success rate).

6. Custom Model Training

Rating: Ease of Use ★★★☆☆ | Functionality ★★★★★ | Speed ★★☆☆☆ | Flexibility ★★★★★

Upload 10-20 images to train Leonardo AI on your specific style, brand aesthetic, or character designs. This feature enables:

• Brand consistency: Generate marketing assets that match your visual identity
• Character consistency: Create multiple poses/scenes of the same character
• Style replication: Mimic specific artistic styles or photography techniques

Testing Results: Model training requires 15-30 minutes per model and consumed significant tokens (approximately 1,000-1,500 tokens per training session). Results varied: simpler styles (flat design, minimalism) trained successfully, while complex artistic styles (oil painting, watercolor) produced inconsistent outputs.

Token Requirements:

• Free plan: Cannot train custom models
• Apprentice: Up to 10 models
• Artisan: Up to 20 models
• Maestro: Up to 50 models

7. Prompt Generation Assistant

Rating: Ease of Use ★★★★★ | Functionality ★★★★☆ | Speed ★★★★★ | Flexibility ★★★★☆

Input a basic concept and Leonardo AI generates 4-8 detailed prompts with specific styling, lighting, and composition suggestions.

Example Transformation:

• Your Input: "office worker at desk"
• AI-Generated Prompt: "photorealistic studio portrait of a professional woman in business attire sitting at a modern minimalist desk, warm natural lighting from large windows, shallow depth of field, 50mm lens, shot on Sony A7III, architectural digest style, 8k resolution"

Testing Results: This feature significantly improved my success rate with photorealistic generations. However, it sometimes over-complicated simple requests, leading to cluttered or unfocused outputs.
