The verdict
Decart Oasis 3 appears in 1 AI-ranked category — best position #3 for world model api.
Positioning brief — for the Decart Oasis 3 team
Why the models put Decart Oasis 3 at #3 for world model api
- Real-time interactive generative video GPT · Claude“genuinely real-time interactive generative video”
- Controllable closed-loop environments GPT · Gemini“controllable closed-loop photorealistic environments”
- Autonomous-driving and embodied-agent training GPT · Gemini“autonomous-driving and embodied-agent training”
- Low-latency unlimited-duration live transformation Claude“MirageLSD transforms live streams frame-by-frame at ~25fps with sub-100ms latency and unlimited duration”
What the models credit World Labs Marble (#1) with — and don’t credit Decart Oasis 3
- Persistent navigable 3D worlds GPT · Gemini · Grok · Claude“persistent, navigable, high-fidelity 3D worlds”
- Geometrically consistent environments Gemini · Grok“persistent, geometrically consistent 3D environments”
- Exportable spatial assets GPT · Claude“exportable spatial assets”
What would move the rank — the models’ fix lines, unified
- Weaker long-horizon consistency and physical state GPT · Claude“weaker long-horizon consistency and explicit physical state than conventional simulation”
- No arbitrary high-fidelity environments or geometry Claude · GPT“it won't generate arbitrary high-fidelity environments or exportable 3D geometry”
- High billing and narrow specialization Gemini · Claude“High API billing rates (~$0.02/second) and narrow specialization for robotics and autonomous driving navigation.”

Best near-tie for real-time interactive video, producing controllable closed-loop photorealistic environments especially valuable for autonomous-driving and embodied-agent training
Gemini Provides a dedicated gRPC SDK for real-time action-conditioned simulation, producing synchronized multi-camera perspectives for closed-loop autonomous training.
Claude The only production API delivering genuinely real-time interactive generative video — MirageLSD transforms live streams frame-by-frame at ~25fps with sub-100ms latency and unlimited duration, and the Oasis line demonstrated fully playable model-generated worlds; near-tie with Sora 2 on this list, ranked below it only because Decart's fidelity and generality are narrower.
Where Decart Oasis 3 falls short, per the models
- GPT Primarily a visual simulator, with weaker long-horizon consistency and explicit physical state than conventional simulation
- Claude Focused on real-time style transformation and game-like demos at modest resolution — it won't generate arbitrary high-fidelity environments or exportable 3D geometry.
- Gemini High API billing rates (~$0.02/second) and narrow specialization for robotics and autonomous driving navigation.
