The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Block diffusion sets a new state-of-the-art performance among diffusion models on language modeling benchmarks and enables generation of arbitrary-length sequences.

C2weakest assumption

The assumption that the proposed training algorithm, estimators of gradient variance, and data-driven noise schedules will produce stable and effective models that generalize beyond the training data without hidden instabilities or overfitting.

C3one line summary

Block diffusion language models interpolate between autoregressive and diffusion models to support flexible-length generation and achieve state-of-the-art performance among diffusion models.
