We find that for a fixed dataset, larger and longer-trained LMs hallucinate less.

To do so, we investigate a simple self-training method based on expectation-maximization, which we call ReST$^{EM}$, where we (1) generate samples from the model and filter them using binary feedback, (2) fine-tune the model on these samples, and (3) repeat this process a few times.

We introduce and study the problem of adversarial arithmetic, which provides a simple yet challenging testbed for language model alignment.
