The labs are already routing internally — different model classes for different requests, ensembles under the hood. What they can't do is route across vendors, or evaluate a competitor's model for a specific sub-task, or use an open-source fine-tune for the narrow piece where it's actually best.
大多数人认为大模型实验室拥有绝对优势,可以解决所有AI问题。但作者认为实验室在模型选择上存在结构性限制,无法跨供应商评估模型或为特定子任务使用开源微调模型。这为专注于特定领域的企业提供了机会,它们可以选择最适合每个子任务的模型,而不仅限于自家实验室的模型。
