Loopy: Low-Bit Quantization Framework for Looped Language Models

Zeyu LI, Yipu ZHANG, Jintao Chen et al. · 2026

Looped language models provide a parameter-efficient way to scale iterative test-time computation by repeatedly executing a shared recurrent core. Post-training quantization (PTQ) can reduce the memory footprint and inference cost of looped language models, but errors introduced by a quantized shared core affect subseq …

S4VY: Segment Anything in Feed-Forward 4D Visual Geometry

Jingdong Zhang, Xin Li, Jan Kautz et al. · 2026

Accurate instance segmentation in dynamic scenes is important for downstream applications such as robotics and autonomous driving. Existing Segment Anything models operate primarily on 2D image or video masks and preserve identity through sequential memory, while promptable 4D instance segmentation built upon feed-forw …

ReCaVSR: One-Step Streaming Diffusion Video Super-Resolution with Recycled Latents and Learned Cache Routing

Xijun Wang, Xin Li, Suhang Yao et al. · 2026

Real-time diffusion-based video super-resolution (VSR) is in high demand for online streaming, yet stringent latency requirements often compromise generative fidelity. We propose ReCaVSR, a Wan2.2-based, one-step framework for streaming VSR that builds on two observations: recycled SR latents retain local temporal cont …
