Ctrl: A conditional transformer language model for controllable generation
arXiv preprint arXiv:1909.05858, 2019•arxiv.org
Large-scale language models show promising text generation capabilities, but users cannot
easily control particular aspects of the generated text. We release CTRL, a 1.63 billion-
parameter conditional transformer language model, trained to condition on control codes
that govern style, content, and task-specific behavior. Control codes were derived from
structure that naturally co-occurs with raw text, preserving the advantages of unsupervised
learning while providing more explicit control over text generation. These codes also allow …

Large-scale language models show promising text generation capabilities, but users cannot easily control particular aspects of the generated text. We release CTRL, a 1.63 billion-parameter conditional transformer language model, trained to condition on control codes that govern style, content, and task-specific behavior. Control codes were derived from structure that naturally co-occurs with raw text, preserving the advantages of unsupervised learning while providing more explicit control over text generation. These codes also allow CTRL to predict which parts of the training data are most likely given a sequence. This provides a potential method for analyzing large amounts of data via model-based source attribution. We have released multiple full-sized, pretrained versions of CTRL at https://github.com/salesforce/ctrl.
