Overview
The Need for High-Fidelity AV Simulation
Developing autonomous vehicles (AVs) requires vast amounts of training data that mirrors the real-world diversity they’ll face on the road. Sensor simulation addresses this challenge by rendering physically-based sensor data in virtual environments. Conditioned on these physics, world foundation models (WFM) add variation to sensor simulation, amplifying lighting, weather, geolocations, and more. With these capabilities, you can train, test, and validate AVs at scale without having to encounter rare and dangerous scenarios in the real world. The precision and diversity in sensor data and environmental interaction are crucial for developing physical AI.
Why AV Simulation Matters:
Safety
Render diverse driving conditions—such as adverse weather, traffic changes, and rare or dangerous scenarios—without having to encounter them in the real world.
Cost Efficiency
Accelerate development and reduce reliance on costly data-collection fleets by generating data to meet model needs.
Scalability and Flexibility
Deploy a virtual fleet to configure new sensors and stacks before physical prototyping.

Running Physically Accurate AV Simulation at Scale
Developers can get started building AV simulation pipelines by taking the following steps.
Reconstruct Real-World Data in Digital Twins & Amplify Data Variation
NVIDIA NuRec provides APIs and tools for neural reconstruction and rendering, allowing developers to turn their sensor data into high-fidelity 3D digital twins, simulate new events, and render datasets from new perspectives.
Cosmos Transfer-1 is conditioned on ground truth and structured data inputs to generate new lighting, weather and terrain—turning a single driving scenario into hundreds. Developers can use prompt as well as sensor data as input to generate different variants of an existing scene.
Both NuRec and Cosmos Transfer-1 are integrated with CARLA, a leading open-source AV simulator. This integration allows developers to generate sensor data from Gaussian-based reconstructions using ray tracing, and to increase scenario diversity with Cosmos WFMs.
With these tools, developers can:
- Simulate new trajectories and camera views in reconstructed scenes
- Use CARLA’s APIs and traffic models to create varied, realistic scenarios
- Leverage behavioral agent models like ITRA and Foretellix for advanced traffic and behavior diversity
The integration includes a starter pack of pre-reconstructed scenes, enabling rapid creation of diverse, corner-case datasets for AV development.
Generate Diverse Scenarios with World Foundation Models
Developers can use the latest NVIDIA Cosmos Predict-2 world foundation model to enhance AV development with faster, scalable synthetic data generation. The WFM has two variants:
- Predict2-2B: Optimized for speed and lower memory usage
- Predict2-14B: High-fidelity outputs for complex scene understanding and temporal coherence.
Cosmos Predict-2 lets developers generate a starting frame from a text prompt, then use that frame to condition longer video sequences, speeding up scenario design. The model is easily post-trained on specific environments, tasks, or camera systems using curated AV data and tools, enabling tailored outputs for different use cases.
Predict-2’s diffusion-based architecture enables text-to-image and video-to-world generation, balancing speed and realism for scalable scenario design.
