Researchers have developed BlockGen, a novel blockwise sequence modeling approach that utilizes hybrid samplers for improved discrete diffusion. This method allows for flexible generation by training on a mixture of block sizes, interpolating between autoregressive and pure diffusion models. BlockGen introduces an AR-informed predictor-corrector sampling technique that combines autoregressive and diffusion predictions to regenerate unlikely tokens, outperforming traditional methods in certain scenarios.
