What Is CFG Scale?
Beginner Guide to Prompt Strength & AI Control
What Is CFG Scale?
CFG Scale (Classifier-Free Guidance Scale) determines how strongly the AI should follow your prompt. It balances creativity and accuracy in the final image.
Why CFG Scale Is Important
- Higher CFG: More literal, accurate interpretation.
- Lower CFG: More artistic freedom and unpredictability.
- Balanced CFG: Natural, creative images that still match the prompt.
Recommended CFG Values
- Low (3β6): Creative, loose, artistic results.
- Medium (7β10): Best balance of accuracy and quality.
- High (11β15+): Very strict prompt following, sometimes leading to distortions.
How CFG Scale Works
The AI compares two versions of the imageβone guided by your prompt and one without any prompt influence. CFG then pushes the model toward the guided version depending on the intensity you choose.
CFG Scale FAQ
Is higher always better?
