PEER: A Collaborative Language Model

Introduces PEER, a collaborative LM that is trained to imitate the entire writing process itself: PEER can write drafts, add suggestions, propose edits and provide explanations for its actions.

PEER can be used to improve collaborative writing processes by providing draft writing, suggestions, and edits, as well as explanations for its actions. It can also be trained on self-training techniques to increase the quality and diversity of data, making it useful in domains without edit histories.
