Decart’s new world model can simulate hours of photorealistic driving — with some caveats

TechCrunch AI · Jun 10, 2026, 1:07 PM

Key takeaways

  • AI startup Decart on Wednesday unveiled Oasis 3, its latest interactive world model that can generate photorealistic driving environments in real time, Tech Crunch has exclusively learned.
  • The startup is initially targeting autonomous vehicle companies that need to simulate rare driving scenarios at scale, and plans to expand into robotics and other physical AI applications.
  • “It s going to be the first usable world model that people can actually program on top of,” Dean Leitersdorf, co-founder and CEO of Decart, told TechCrunch.

Why this matters: a development in AI with implications for how people work, create, and decide.

AI startup Decart on Wednesday unveiled Oasis 3, its latest interactive world model that can generate photorealistic driving environments in real time, Tech Crunch has exclusively learned. The model is currently available via API.

The startup is initially targeting autonomous vehicle companies that need to simulate rare driving scenarios at scale, and plans to expand into robotics and other physical AI applications. But the bigger bet is on developers: By offering API access from day one, Decart is trying to build a developer ecosystem around world models much like how OpenAI did with language models.

“It s going to be the first usable world model that people can actually program on top of,” Dean Leitersdorf, co-founder and CEO of Decart, told TechCrunch. “I think there s going to be an entire developer community that emerges on top of this.”
