ai-msgbot: GPT2-XL-dialogue

GPT2-XL (~1.5 B parameters) trained on the Wizard of Wikipedia dataset for 40k steps with 33/36 layers frozen using aitextgen. The resulting model was then further fine-tuned on the Daily Dialogues for 40k steps, with 34/36 layers frozen.

Designed for use with ai-msgbot to create an open-ended chatbot (of course, if other use cases arise, have at it).

conversation data

The dataset was tokenized and fed to the model as a conversation between two speakers, whose names are below. This is relevant for writing prompts and filtering/extracting text from responses.

script_speaker_name = person alpha

script_responder_name = person beta


  • the default inference API examples should work okay
  • an ideal test would be explicitly adding person beta into the prompt text the model is forced to respond to instead of adding onto the entered prompt.

The dialogues in the dataset reflect our daily communication way and cover various topics about our daily life. We also manually label the developed dataset with communication intention and emotion information. Then, we evaluate existing approaches on DailyDialog dataset and hope it benefit the research field of dialog systems. The dataset is available on \url{http://yanran.li/dailydialog}",
