Decart launches Oasis 3 API for real‑time photorealistic driving sims

Decart opened its Oasis 3 world model to developers on June 10, 2026 via a cloud‑hosted API.
The service renders photorealistic driving environments in real time, requiring a single RTX 4090‑class GPU to achieve about 30 fps at 1080p. It supports dynamic weather, traffic density controls, and sensor‑level outputs (LiDAR, radar, camera). Pricing starts at $0.12 per simulated minute, with a free tier for up to 20 minutes daily.
By offering an off‑the‑shelf API, Decart hopes to cut the cost of building custom simulators. Nvidia’s Omniverse runs a similar scene at roughly 20 fps on comparable hardware, while Waymo’s internal stack, which runs on specialised clusters, is not publicly priced but is known to be far more resource‑intensive. Oasis 3 therefore positions itself as a cheaper, developer‑friendly alternative for midsize AV teams.
The launch still carries caveats: lighting glitches appear in extreme sunlight, and the model’s physics are tuned for passenger‑car dynamics, not heavy‑vehicle behavior. Still, the move signals a shift toward commoditising high‑fidelity simulation.
