Task Specific Automated Evaluators With Sensible Defaults

via “standardized multi-task evaluation harness”

23 hardest BIG-Bench tasks where models initially failed.

Unique: Provides unified evaluation infrastructure across heterogeneous task types (arithmetic, logic, spatial, causal) with consistent metrics and result aggregation, rather than requiring task-specific evaluation code. This standardization enables reproducible cross-model comparison and reduces evaluation implementation burden.

vs others: More reproducible than ad-hoc evaluation because it enforces consistent metrics and input/output handling; more comprehensive than single-task benchmarks because it enables multi-domain capability assessment in one evaluation run.
