Aurora 1.5 incorporates 22 additional variables into the foundation model. The model now supports hourly temporal resolution. It also includes probabilistic ensemble forecasting. These additions increase the model's utility for real-world weather, climate, and energy applications. The updates provide more granular data and improved forecasting accuracy. This facilitates more detailed analysis and decision-making in these domains.

ARC-Bench: Evaluating Action Ranking in Frozen JEPA World Models

ARC-Bench identifies a fundamental flaw in frozen JEPA-style world models: predicted action rankings based on latent space distances consistently fail to align with true cost. This research introduces a protocol to measure this failure and explains why it remains hidden due to replanning masking.
