How long does it take to Train Assistant? How long does training take?
After you hit Train Assistant, it can take up to a few minutes (1-2) to train your assistant. Typically, the timing depends on the number of intents and other conversation logic (utterances & entities) in your Model Manager/NLU model.
Upon completion of the training of your assistant's model, you will notice that the Train Assistant button is greyed out and you are now using the highest-fidelity testing for your assistant.
