# Prompt Strength (CFG)

(It's really not prompt strength...)

This value roughly equates how rigidly a model follows its instructions during generation. This depends on how your model was trained. For most modern models a value of 7 is perfectly acceptable. If the model is over trained (which means, you ask for a car and get a woman) lowering the CFG value can help.

As you can see, on very high CFG you also need to increase the number of steps.
