Waymo Catches World Model Fever, and the Only Prescription Is More World Models

Waymo Unleashes AI-Powered World Model to Prepare Self-Driving Cars for the Unexpected—From Tornadoes to Elephants

In a bold move that blends cutting-edge artificial intelligence with the unpredictable chaos of real-world driving, Waymo has unveiled its latest innovation: the Waymo World Model. This generative AI system, built on Google DeepMind’s Genie 3, is designed to simulate near-endless driving scenarios—including the rarest and most extreme—to ensure Waymo’s autonomous vehicles are ready for anything. From tornadoes to elephants on the road, the company is betting big on AI to tackle the unpredictable.

Waymo has already logged over 200 million miles of autonomous driving on public roads, but as the company admits, there are still scenarios it hasn’t encountered—and likely won’t—until it’s too late. Enter the Waymo World Model, a tool that leverages Google’s Genie 3 to generate hyper-realistic, interactive environments that go beyond the data collected from Waymo’s fleet of sensors and cameras.

Unlike traditional large language models (LLMs) that predict the next word in a sequence, world models like Genie 3 are trained on the dynamics of the real world, including physics and spatial properties. This allows them to create simulations of how physical environments operate, making them ideal for testing autonomous vehicles in scenarios that are too rare, dangerous, or impractical to replicate in the real world.

Simulating the “Impossible”

Waymo’s goal is to use the World Model to prepare its vehicles for scenarios that are statistically improbable but potentially catastrophic. These include:

• Extreme weather conditions: How would a Waymo vehicle navigate a tornado or flood waters?
• Sudden safety emergencies: What happens if a tree branch falls onto the road or there’s an accident with debris scattered everywhere?
• Unexpected encounters: How would the car react to an elephant suddenly appearing on the road?

“By simulating the ‘impossible,’ we proactively prepare the Waymo Driver for some of the most rare and complex scenarios,” the company said in a statement.

The Promise and Pitfalls of World Models

While the theory behind Waymo’s approach is sound, world models are still in their infancy. Early feedback on the consumer version of Genie 3 has been mixed, and like all AI systems, world models are susceptible to hallucinations—generating unrealistic or nonsensical scenarios. However, Waymo is confident that its vast trove of high-definition data, combined with Genie 3’s capabilities, will allow it to create simulations that are both realistic and useful.

Real-World Challenges Remain

Despite Waymo’s technological advancements, its vehicles have faced criticism for their handling of edge-case scenarios in the real world. In late 2025, a Waymo car tragically ran over a beloved neighborhood cat named Kit Kat, sparking outrage among residents. More recently, in January 2026, a Waymo vehicle struck a child in a school zone, prompting an investigation by U.S. regulators.

These incidents highlight the challenges of autonomous driving, even in scenarios that aren’t particularly rare for human drivers. While the Waymo World Model aims to address these issues by preparing vehicles for the unexpected, it remains to be seen how effective it will be in practice.

The Future of Autonomous Driving

Waymo’s use of AI to simulate rare and extreme scenarios represents a significant step forward in the development of autonomous vehicles. By leveraging world models, the company is not only improving the safety and reliability of its cars but also pushing the boundaries of what AI can achieve in the real world.

As the technology continues to evolve, it’s clear that the future of autonomous driving will depend on the ability to anticipate and prepare for the unexpected. With the Waymo World Model, the company is taking a bold step in that direction—one that could redefine the way we think about self-driving cars.
