Current obstacles

Extended interaction consistencyMaintaining coherent scene state during long interactions remains difficult; hallucinations emerge after sustained use.
Physics accuracy versus speed trade-offBalancing photorealism and physical plausibility with real-time performance; far-field accuracy lags near-field.
Sim-to-real transfer for robot controlRobots trained on Oasis simulations often fail in real environments due to unmodeled physics and sensor differences.

Physics limits

Transformer scaling for real-time inferenceTransformers scale quadratically with sequence length; maintaining full context over long videos at 20+ FPS requires hardware advances.
Physical simulation accuracyReal-time physics engines trade accuracy for speed; cannot capture all real-world phenomena at video resolution.

How it works

3 parts

Real-time video

Lucy: live video transformation

Lucy 2.5 transforms video in ~40ms, enabling pose-driven and text-prompt edits. Used for try-on and live advertising.

Physics sims

Oasis: world model for robotics

Oasis 3 generates physics-accurate simulations at 22 FPS from text prompts and vehicle control inputs. Maintains 3-view multi-camera consistency.

Hardware stack

DOS: multi-hardware acceleration

DOS 2.0 optimizes across Nvidia GPUs, Google TPUs, Amazon Trainium. Achieves 8x typical token throughput and 100 fps video generation.
