Long-horizon multimodal mem/world models

Key Questions

What performance does Flash-WAM deliver?

Flash-WAM achieves a 23x speedup in long-horizon multimodal memory and world-model workloads.

How does ARROW reduce forgetting compared with DreamerV3?

ARROW cuts forgetting by 20x relative to DreamerV3 while maintaining long-horizon performance.

What TSR score is reported for SpatialWorld GPT-5?

SpatialWorld GPT-5 records 17.4% TSR on the evaluated spatial-reasoning tasks.

What key finding does the Imagined Rollouts paper present?

It diagnoses that world-model rollouts are primarily kinematic rather than dynamic, with DreamerV3 rollouts approximately 100x more kinematic than real dynamics.

What efficiency gains does Light-Omni provide for video agents?

Light-Omni delivers a 12.1x speedup and 2.6x memory reduction by favoring reflex over reasoning with long-term memory.

What tasks does the RoboDojo benchmark cover?

RoboDojo supplies a unified sim-and-real benchmark containing 42 simulation and 18 real-world robot-manipulation tasks.

What is MIRA and its runtime performance?

MIRA is a multiplayer interactive world model trained on Rocket League that runs at 20 fps on a single GPU.

How does SIEVE affect data needs for VLA imitation learning?

SIEVE's structure-aware selection reduces required training data by 50% while preserving policy performance.
