WAM-Sim0.1: World Anchored Memory Meets Online RL for Consistent and Realistic Driving Simulation

WAM‑Sim0.1 is a driving world model that uses a persistent hierarchical memory to anchor context across pose, scene, and instance tokens, addressing structural, identity, and quality drift in autoregressive simulations. It incorporates online flow‑matching reinforcement learning to refine self‑generated rollouts, guided by visual rewards and a vision‑language physical judge, thereby improving visual sharpness and physical plausibility. On the nuScenes benchmark, WAM‑Sim achieves high generation fidelity (FID = 3.47, FVD = 25.72) and strong downstream perception metrics (24.16 mAP, 71.23 road mIoU), while maintaining scene similarity and identity coherence over minute‑scale rollouts.

HorizonComposer: Spatiotemporally Consistent Driving Video Editing with Enriched Traffic Semantics

HorizonComposer is a new instruction‑guided video editing framework that preserves traffic semantics in driving videos. It uses a hybrid dataset of real and synthetic edits, applies advantage conditioning with dense pixel‑level rewards during training, and introduces thinking frames to reduce temporal shock. Experiments show state‑of‑the‑art spatiotemporal consistency, improved content preservation, and gains in downstream road line segmentation and multi‑object detection.

SimVTA: Simulation-Grounded Video-Trajectory Alignment for Driving World Action Models

SimVTA is a post‑training framework that enhances driving world action models by aligning simulated future videos with candidate trajectories. It samples trajectories, renders high‑reward futures in a real‑world simulator using 3D Gaussian Splatting, and prioritizes video supervision for high‑error futures. The approach improves planning performance, raising PDMS from 86.2 to 91.3 on NAVSIM v1 and achieving strong results on NAVSIM v2 and HUGSIM.

TerraTransfer++: Demonstration-Free End-to-End Planner

TerraTransfer++ demonstrates a demonstration‑free, end‑to‑end autonomous driving framework that leverages self‑play in vectorized simulators to pretrain a policy. The method distills self‑play rollouts into a flow‑matching trajectory teacher and trains lightweight adapters on a frozen vision backbone, using action KL divergence, a batch‑relational low‑rank loss, and trajectory‑matching loss. The resulting closed‑loop policy surpasses all published imitation‑based methods on the HUGSim benchmark, while the planner achieves state‑of‑the‑art performance on NAVSIM navhard and navtest without any human demonstrations.

NVIDIA OmniDreams: Real-Time Generative World Model for Closed-Loop Autonomous Vehicle Simulation

As autonomous vehicle capabilities advance, the safe evaluation of driving policies in long-tail scenarios remains a critical bottleneck. In closed-loop simulation, the driving policy model actively interacts with the environment, where its actions dynamically update the simulator state and directly influence the next set of generated sensor observations.

DriveVLA-M0: Failure-Aware Memory Augmentation for Autonomous Driving

DriveVLA-M0 introduces a failure-aware latent memory system for Vision‑Language‑Action models in autonomous driving. It stores past failure cases with scene representations and expert trajectories, and uses a retrieval model to decouple static road structure from dynamic agent interactions. During inference, retrieved cases are injected via a lightweight LoRA‑based test‑time training mechanism, yielding significant performance gains on NAVSIM benchmarks with minimal latency overhead.
