DialoGPT adapts pretraining techniques to response generation using hundreds of Gigabytes of colloquial data. Like GPT-2, DialoGPT is formulated as an autoregressive (AR) language model, and uses a multi-layer transformer as model architecture. Unlike GPT-2, which trains on general text data, DialoGPT draws on 147M multi-turn dialogues extracted from Reddit discussion threads. The implementation is based on the huggingface pytorch-transformer and OpenAI GPT-2.
