Chintha and colleagues present CADENCE, a decoding method that lets a language model choose between generating one token normally and proposing a longer continuation in parallel.

1-8B-Instruct with Gaussian prediction heads, each trained to represent a future span of a particular length as a fixed-dimensional latent vector.
