This might be a silly question, but I’m wondering if there is a way to identify the number of iterations used for a model after the model is fit. Is the number of iterations used still derivable from the model summary or any other matrices?

Sorry if it is unclear, my question is about retrieving the number of iterations used after the model is fit. Is there a way to retrieve this info? More specifically, I have a model fit and would like to query the number of iterations used in this model. Assuming that I do not have access to the model structure where I can see iter = 15000. I hope this makes clearer now.
