Unverified60% confidenceOpinionExact time
For the vast majority of application scenarios, models with a higher cost-performance ratio in the middle of the leaderboard are often the optimal engineering solution, and it is not necessary to choose the most capable model.

UnverifiedIn multi-agent scenarios, a model's cost efficiency is often more important than its peak capability.76% similarUnverifiedThe benefits of model-agnostic design include: controllable cost (use a small model for simple tasks, switch to a large model for complex tasks), avoiding vendor lock-in (smooth migration when a vendor raises prices or discontinues service), and meeting compliance requirements (sensitive code can go only through local inference).75% similarUnverifiedWhen choosing a model, the key question is to find the model that passes the evaluation set with acceptable accuracy and has the lowest running cost, not the smartest model.75% similarUnverified"Cost per correct answer" used alone rewards the cheapest barely-good-enough model; the correct framing is to first fix a quality floor, then find the most economical path that satisfies that floor.74% similarUnverified选型应按任务结构而非模型名气选择，若三问（多步执行且可能改计划、错误成本高、结果可验证）都为是则优先用Opus 5，只有一个为是则先用更便宜的模型74% similar
