ABSTRACT

Contemporary generative video architectures struggle to maintain persistent geometric consistency over extended temporal horizons and routinely violate fundamental conservation principles. We present Nuvi-X DiT-4D, a continuous generative world model operating directly over a 4D spacetime manifold parameterized by Lie algebra \(\mathfrak{se}(3)\) transformations and symplectic Hamiltonian constraints. By training across 180,000 GPU cluster hours on 24 million multimodal trajectories, our system achieves sub-5ms interactive inference latency at 120 FPS while preserving 99.94% energy and momentum conservation across multi-agent environments.

1. Introduction & Mathematical Motivation

Autonomous vehicles, robotic manipulation, and aerospace navigation require predictive world representations that are not only photorealistic but physically faithful. Discretized 2D frame prediction methods introduce accumulation error \(\mathcal{O}(\Delta t^2)\) that causes rapid hallucination. Nuvi-X parameterizes the physical world state as a continuous trajectory in phase space:

\[ \mathbf{z}(t) = (\mathbf{q}(t), \mathbf{p}(t)) \in \mathcal{M}^{4D} \] \[ \frac{d\mathbf{q}}{dt} = \frac{\partial \mathcal{H}}{\partial \mathbf{p}}, \quad \frac{d\mathbf{p}}{dt} = -\frac{\partial \mathcal{H}}{\partial \mathbf{q}} \]

Where \(\mathcal{H}(\mathbf{q}, \mathbf{p})\) denotes the learned Hamiltonian representing total kinetic and potential energy of all participating entities in the scene.

2. Multi-Modal Sensorium Decoupling

Unlike video models that produce flattened RGB images, the Nuvi-X latent space directly decodes into four synchronized operational sensor streams:

1. Photorealistic 4K RGB
Rendered via 1.4M 4D dynamic Gaussian primitives with spherical harmonics.
2. 3D LiDAR & Depth
Unbiased sub-millimeter Euclidean range sweeps with realistic atmospheric attenuation.
3. Neuromorphic Event Spikes
Temporal contrast changes at microsecond temporal resolution for extreme-speed autonomy.
4. Inertial & Haptic IMU
6-DOF accelerations and angular rates matching continuous vehicle suspension dynamics.

3. Distributed Tensor Cluster Scaling Laws

Pre-training our 32-billion parameter foundation world model necessitates massive distributed tensor parallelism. Our cluster configuration utilizes 512 matrix acceleration nodes interconnected over 3.2 Tbps non-blocking InfiniBand fabrics:

Total Compute Utilized: 180,000 GPU Cluster Hours
Training Batch Size: 4,096 Synchronous Trajectories
FP8 Tensor Throughput: 940 PFLOPS Peak
Scaling Efficiency: 91.4% Linear Efficiency across 512 Nodes
