SemanTok: Predictable Semantic Tokens for Efficient Autoregressive Video Generation

arXiv 2026 19.6 method

TLDR

SemanTok introduces a flexible video tokenizer using frozen DINO features and prefix reconstruction heads to improve semantic alignment and fidelity for autoregressive video generation.

Reasoning

The paper presents a novel tokenizer with clear empirical benefits over larger models and strong semantic alignment, including out-of-distribution robustness. However, its scope is limited to tokenization, and direct evidence about world model dynamics prediction or interactive settings is not evident from the abstract.
