Wave Forcing overlaps denoising stages to stream video faster, with more motion

By letting each video chunk see only earlier, cleaner chunks, a new method pipelines generation across GPUs. It matches a strong baseline on quality and shows much more motion.

Streaming video generators build footage chunk by chunk, and each chunk needs several passes through the model before the next one can start. Wave Forcing changes what each chunk is allowed to see: only earlier, cleaner chunks. That lets several chunks be processed at once in a pipeline that outputs one finished chunk per round. On Wan2.1-T2V-1.3B, the authors report VBench quality comparable to Rolling Forcing, with much higher motion scores. On eight H200 GPUs they report 134.8 end-to-end frames per second. The quality tests used only the 1.3B model.

LLM-guided search finds cheaper quantum circuits in seven of eight benchmark tasks

A language model proposes circuit designs, a strict classical checker verifies and scores them, and the results beat prior designs while making a previously impractical classical algorithm usable in quantum form.

Soft-MTP: a one-line change strips noise out of multi-token prediction training

A new preprint finds that the standard way of training multi-token prediction heads hides a noisy gradient term. Removing it improved perplexity, speculative decoding and reasoning at no measurable extra cost.
