Multi-step reasoning is the workload frontier pricing was built on — and the one where the "do I need it" question has a measurable answer. The suite scores multi-step problems with deterministic ends, so a model’s reasoning is graded on reaching the right result, not on showing appealing work.
These two are part of a larger measured frontier — when do you need a reasoning model shows every measured option for this workload, and other workloads rank these models differently: a model that wins here can lose on another kind of work, which is the whole argument for routing per workload rather than picking one model for everything.
