Classifier-free guidance combines conditional and unconditional diffusion predictions at sampling time to trade off prompt adherence, sample quality, and diversity.

The classifier-free guidance paper jointly trains conditional and unconditional predictions and combines their score estimates during sampling. Increasing guidance can change the quality-diversity tradeoff and may reduce diversity or cause artifacts. Standard implementation often evaluates the model for both conditional and unconditional inputs per denoising step. Exact behavior depends on the model’s parameterization and implementation.
Train with condition dropout to obtain conditional and unconditional behavior.
Adjust guidance scale in a controlled comparison.
Measure both prompt adherence and output diversity.
Account for the additional model evaluation used by standard guidance.
Guidance remains an inference-time control with tradeoffs. Tune and evaluate it for the specific model and task rather than assuming larger values always improve results.
