Chatty like app

Hi guys, I am completely new to the NLP universe and am teaching myself as I go. I am trying to build a NLP powered chatbot that is designed to be an ‘emotional’ companion or friend of sorts. Similar to huggingface’s Chatty app or Luka’s Replika app. Right now, I’m thinking of using GPT-2 and fine tuning it on various corpuses.

My questions are:

  • for what i’m trying to build, is this the most effective approach?
  • What tech/models were used in huggingface’s Chatty app?

Thanks in advance!
