I found model.predict and model.predict_proba both give an identical 2D matrix representing probabilities at each categories for each row.
model.predict
model.predict_proba

Just a remark : In fact you have both predict and predict_proba in most classifiers (in Scikit for example). As already mentioned, the first one predicts the class, the second one provides probabilities for each class, classified in ascending order.
predict
predict_proba
