differentiate nlu and core response

hi, I have nlu model and rasa core enabled. But when I am giving expression related to action getting core response. but when I am trying to give user expression which is trained as Rasa NLU, still rasa core response is returned. How can I differentiate core and nlu response

Hello @kdigumar, welcome to the forum!

Unfortunately, I don’t understand your question. Put (a bit too) simply: Rasa NLU takes a user utterance and creates an intent. This intent is then taken by Rasa Core to predict the next system action. Have you read through the Getting Started with Rasa guide?
