What is the role of CFG Scale in Stable Diffusion? In Stable Diffusion, the CFG Scale operates with an inverse relationship between fidelity and quality. Increasing the CFG Scale value leads to an output image that aligns more closely with the input prompt or image, but this comes at the cost of diminished quality. The strength of denoising influences the level of creativity the AI may inject into the output, while the CFG Scale governs how faithfully the result mirrors the input prompts. By fine-tuning both of these settings, I can reach the optimal mix of innovation and precision in my stylization.
For guidance, use a CFG Scale value within the range of 7 to 9. Elevate the value if the generated image deviates from the prompt. It's advisable to avoid the extreme values of 1 and 20, as the correct setting hinges on both the specific results you're aiming for and the intricacy of the text prompt.
Here's a rudimentary chart to show the inverse relationship between fidelity and quality.
