Decart's new world model can simulate hours of photorealistic driving — with some caveats
Decart is launching Oasis 3, a real-time world model that generates photorealistic driving environments for autonomous vehicle testing, now available via API for developers to build on.
TL;DR
- 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.
