HuggingFace has published a new web interface for the small (117M parameter) and medium (345M parameter) versions of GPT-2 that let you interact directly with the model, by writing a prompt, asking for several completions using a customizable decoder, editing the completions if needed and asking further completions.

It’s a great way to test how the model reacts to various probing patterns and content, investigate what kind of common sense is stored in the model and to test future interfaces of creative writing in which a human and a language model could collaborate together.
