ReWorld keeps 64 seconds of world memory

ReWorld’s interactive world model uses a fixed 12-chunk cache to regenerate the starting view after a 64-second, 384-latent out-and-back rollout, while its distilled mode streams 704×1,280 video in four steps, according to the research paper. The result is a research benchmark rather than a deployable simulator, but it gives builders a concrete memory target: test whether an agent can preserve spatial evidence across a bounded cache, alongside the archive’s evidence-first account of AI in clinical workflows.
