FrameMorrow: Future-guided Frame Selection with Prospective Tokens for Long-Horizon Video Generation

Bo Yin, Xiaobin Hu, Jiaqi Zhao et al. · 2026

Long-horizon video generation requires models to effectively leverage an increasingly long generation history. As the generated history grows, retaining all previous content becomes increasingly expensive and redundant, making effective historical selection essential. Existing approaches often determine historical rele …

QuantWM: Temporally Consistent 2-Bit KV Cache Quantization for Video World Models

Jiaqi Zhao, Xiaobin Hu, Bo Yin et al. · 2026

Video world models achieve long-range temporal consistency by storing KV cache during generation, but the growing cache makes KV cache memory a major deployment bottleneck, which motivates low-bit quantization study for efficiency. Existing 2-bit KV cache quantization methods can achieve nearly lossless performance on …
