A user needs careful reasoning over a complex strategic trade-off where answer quality matters more than latency or price. Which model family is the best starting point?
- A.Haiku solely because it is fastest for now.
- B.Opus, followed by evaluation against the task's quality requirements.
- C.Any model without testing because model choice never matters.
