Decart unveils Oasis 3 world model for photorealistic driving simulation
12 reported2 unconfirmed
AI startup Decart on Wednesday unveiled Oasis 3, an interactive world model that generates photorealistic driving environments in real time, available via API. The company is initially targeting autonomous vehicle companies and plans to expand into robotics and other physical AI applications. Decart is offering API access from day one to build a developer ecosystem around world models, similar to OpenAI’s approach with language models. The model is priced at $0.02 per second, with enterprise pricing depending on use cases. Oasis 3 is based on Decart’s real-time video model Lucy and represents the company’s push into physical AI. The release follows Decart raising $300 million a few weeks ago, boosting its valuation to nearly $4 billion, with strategic investors including Toyota, Adobe, eBay, and Nvidia. In testing, the model delivered strong initial scenes from a text prompt but showed significant degradation over time, with thematic integrity fading and controls becoming unresponsive.
What’s reported
Decart unveiled Oasis 3 on Wednesday, June 10, 2026.
The model generates photorealistic driving environments in real time and is available via API.
Access is priced at $0.02 per second; enterprise pricing depends on use cases.
Decart has a community of more than 100,000 developers building on its real-time video model Lucy.
Decart raised $300 million a few weeks before the unveiling, boosting its valuation to nearly $4 billion.
Strategic investors in the round include Toyota, Adobe, eBay, and Nvidia.
Oasis 3 generates physically accurate, multi-camera environments (one front-facing, two side-facing).
In testing, the model’s thematic integrity degraded rapidly as the user moved through the world.
The model sometimes drives through other cars, indicating it does not simulate physics properly.
Decart CEO Dean Leitersdorf called the physics issue a “major research problem that we’re cracking now.”
Oasis 3 is auto-regressive, generating one frame at a time and looking back at previous frames.
Leitersdorf said the team is working to improve the model’s memory length to maintain consistency.
Open questions
Whether Oasis 3 will solve the consistency and physics issues in future versions.
How many developers will build applications using Oasis 3 in the next three months.
