CFG Scale

Parameter controlling how closely AI follows prompts.

In Simple Terms

Parameter controlling how closely AI follows prompts.

What is CFG Scale?

Classifier-Free Guidance (CFG) scale controls how strongly the model follows text prompts. Higher values mean stricter prompt adherence but can reduce image quality or creativity. Lower values allow more variation but may ignore prompt details. Typical values range from 5-15, with 7-8 being common defaults. CFG scale is crucial for balancing prompt accuracy with image quality.

How CFG Scale Works

Understanding how CFG Scale functions is essential for anyone working with AI tools. At its core, this concept operates through a combination of algorithms, data processing, and machine learning techniques that have been refined over years of research and development.

In practical applications, CFG Scale typically involves several key processes: data input and preprocessing, computational analysis using specialized models, and output generation that provides actionable insights or results. The sophistication of modern AI systems means these processes happen rapidly and often in real-time.

When evaluating AI tools that utilize CFG Scale, consider factors such as accuracy, processing speed, scalability, and how well the implementation aligns with your specific use case requirements.

Frequently Asked Questions

What CFG scale should I use?
Start with 7-8. Increase if the model ignores prompts; decrease if images look oversaturated or artificial.
Why do high CFG values look bad?
Very high CFG causes color oversaturation and unnatural artifacts. The model overfits to the prompt at the cost of image quality.
Does optimal CFG vary by model?
Yes, different models have different sweet spots. Experiment with each model to find best results.
