Two tools, side by side. Openness included.

• Highest physics accuracy score among evaluated world models on VBench 2 and PAI-Bench benchmarks
• Runs in real time, unlike many competing simulation approaches
• Handles open-ended, interactive rollouts that respond to user actions — not just pre-prompted video generation
• Supports sequences far longer than prior work, capturing dynamics that only emerge over longer time horizons

• Generate 120+ seconds of real-time world simulation from a single starting state
• Simulate physical dynamics including mechanics, materials, and multi-view consistency
• Condition on arbitrary input actions via latent space embeddings for precise real-time control
• Achieve state-of-the-art physics accuracy with a VBench 2 physics score of 58.52
• Run on an autoregressive diffusion transformer (AR DiT) architecture trained on hundreds of NVIDIA B200 GPUs

Odyssey-2 Max uses a causal AI architecture to predict future world states step by step, enabling real-time interactive simulation of physical environments.
