ThinkOmni: Lifting Textual Reasoning to Omni-modal Scenarios via Guidance Decoding

ICLR 2026poster

Omni-modal reasoning is essential for intelligent systems to understand and draw inferences from diverse data sources. While existing omni-modal large language models (OLLM) excel at perceiving diverse modalities, they lack the complex reasoning abilities of recent large reasoning models (LRM). Howe…

UniFuture: A 4D Driving World Model for Future Generation and Perception

ICRA 2026poster

We present UniFuture, a unified 4D Driving World Model designed to simulate the dynamic evolution of the 3D physical world. Unlike existing driving world models that focus solely on 2D pixel-level video generation (lacking geometry) or static perception (lacking temporal dynamics), our approach brid…

HERMES: A Unified Self-Driving World Model for Simultaneous 3D Scene Understanding and Generation

ICCV 2025poster

Driving World Models (DWMs) have become essential for autonomous driving by enabling future scene prediction. However, existing DWMs are limited to scene generation and fail to incorporate scene understanding, which involves interpreting and reasoning about the driving environment. In this paper, we…

A Unified Framework for 3D Scene Understanding

NeurIPS 2024poster

We propose UniSeg3D, a unified 3D scene understanding framework that achieves panoptic, semantic, instance, interactive, referring, and open-vocabulary segmentation tasks within a single model. Most previous 3D segmentation approaches are typically tailored to a specific task, limiting their underst…
