Decart’s new world model can simulate hours of photorealistic driving — with some caveats AI startup Decart has launched Oasis 3, an interactive world model capable of generating photorealistic driving environments in real time via API. The model targets autonomous vehicle companies needing to simulate rare scenarios at scale, with the broader goal of fostering a developer ecosystem around world models. While impressive in its initial realism and infinite generation capability, Oasis 3 faces challenges with maintaining thematic consistency and proper physics simulation over extended periods.

• Decart has launched Oasis 3, an interactive world model that generates photorealistic driving environments in real time.
• The model is available via API and is initially targeting autonomous vehicle companies.
• Decart aims to build a developer ecosystem around world models, similar to OpenAI’s approach with language models.
• Oasis 3 is based on Decart’s real-time video model Lucy and represents a push into physical AI.
• The model’s strengths include photorealism and infinite generation capability, supported by Decart’s efficient DOS software.
• Competitors in the world model arena include Google’s Genie 3 and Fei-Fei Li’s World Labs’ Marble.
• Testing revealed that while initial scenes are realistic, thematic integrity degrades over time, and physics simulation (e.g., cars driving through each other) is inconsistent.
• Decart is working on improving the model’s memory and context window to address consistency issues.
• The startup recently raised $300 million at a nearly $4 billion valuation, with investors including Toyota, Adobe, eBay, and Nvidia. Continue reading https://techcrunch.com/2026/06/10/decarts-new-world-model-can-simulate-hours-of-photorealistic-driving-with-some-caveats/
