Editorial commentary

BIG-bench (Srivastava et al., 2023) emphasises task diversity: arithmetic, logic, multilingual translation, theory-of-mind, common-sense, code, and intentionally adversarial probes. The 'BIG-bench Hard' subset captures the hardest tasks where models showed substantial headroom; it has been heavily reused as a comparison set.
