What is CFG Scale? How to Adjust It for Better AI Images

CFG Scale Explained

CFG (Classifier-Free Guidance) Scale controls how strictly the AI follows your prompt vs. being creative on its own.

Low CFG (1-4): More creative, dreamy, abstract. AI takes liberties.
Medium CFG (5-8): Balanced. Good for most use cases.
High CFG (9-15): Strictly follows prompt. Can look oversaturated or artificial.
Very High CFG (15+): Often produces artifacts. Not recommended.

Tip: Flux models use a different guidance mechanism, so they work best at low CFG (3-4). Using CFG 7+ with Flux often produces worse results.
