The Well: A Multi-Domain Benchmark for Physics Foundation Models

The Well paper systematically organizes data from 16 physics simulation domains and proposes a unified interface and evaluation protocol, arguing for the feasibility and benefit of cross-domain pretraining (Physics Foundation Model). It is a must-read for entering physics-AI foundation-model research.

Highlights

• Unified multi-domain interface lowers cross-domain training barriers
• Pretraining baselines enable fair comparison
• Emphasizes data quality and diversity for generalization
