Decart just dropped Oasis 3, a real-time world model that generates photorealistic driving environments for autonomous vehicle testing. The product is now available via API, meaning developers can plug directly into it and start building simulation applications without training their own models from scratch.

The money behind the model

Oasis 3 arrives on the heels of a $300M funding round completed in May 2026, which valued Decart at approximately $4B. That’s a significant number for a company founded just three years ago in 2023.

Radical Ventures led the round, with Nvidia, Adobe Ventures, Toyota Ventures, Sequoia, and Benchmark all participating.

Total funding raised by Decart now exceeds $450M.

The funding round also introduced the Decart Optimization Stack (DOS) 2.0, which enhances high-performance inference capabilities.

Why photorealistic driving simulation matters

Oasis 3 is Decart’s answer to the fidelity gap in simulation. By generating photorealistic, interactive environments in real time, it allows AV developers to test edge cases, rare scenarios, and dangerous situations without putting anyone at risk.

The API model is a deliberate strategic choice. Rather than building end-to-end AV simulation platforms itself, Decart is positioning Oasis 3 as infrastructure that other companies build on top of.

Decart’s earlier Oasis versions, first made public on October 31, 2024, demonstrated interactive open-world capabilities. Oasis 3 narrows the focus specifically to driving environments, trading breadth for domain-specific accuracy.

The company operates across both Israeli and US markets. Decart also offers the Lucy model for immersive experiences, with the Oasis line serving as the company’s dedicated simulation product.
