Leonardo AI Pro Tips and Shortcuts

After testing Leonardo AI for two years, here are my best tips.

These are the settings I change on almost every project:

Raccourcis clavier

Fonctionnalités cachées que la plupart des gens ignorent

• Blueprints: Run multi-step tasks in one click. For example, swap a grey background for a sunset.
• Flow State: Feed one prompt and rapidly explore many visual ideas before you commit credits.
• Image guidance: Upload a reference picture so faces, elements and camera framing stay consistent.
• Prompt Magic: Improves adherence to your prompt when the model keeps ignoring small details.

Leonardo AI Common Mistakes to Avoid

Mistake #1: Ignoring the recommended aspect ratio

Mistake #2: Writing bloated prompts

Mistake #3: Expecting a perfect first try

Leonardo AI Troubleshooting

Problem: Out of tokens error

Cause: Free users receive a limited number of daily tokens that reset each day.

Réparer: Wait for the daily refresh or move to paid plans. Paid users have a larger monthly token quota with rollover.

Problem: The picture ignores part of my prompt

Cause: Long requests confuse the standard generation mode.

Réparer: Switch on raw mode. Using raw mode helps with longer and complex prompts. Add negative prompts to remove stray elements.

Problem: Colors bleed between objects

Cause: The model cannot tell which color belongs to which object.

Réparer: Use specific details, such as red jacket and grey wall, instead of one long clause.

📌 Note: If none of these fix your issue, contact Leonardo AI support.
