 ## Listening for inference steps
 
 To monitor the progress of image generation, you can pass an `inferenceCallback` function to the constructor. The callback is invoked at each denoising step (for a total of `numSteps + 1` times), yielding the current step index that can be used, for example, to display a progress bar.
