Let Models Choose Models: Embedding-Driven Smart Routing for LLMs
In an AI architecture where multiple models coexist, such as GPT-4, GPT-4o, lightweight models, and vertical-domain models, one core question is: How can the system automatically select the most suitable model without explicitly specifying a model ID? This article introduces an engineering-friendly approach: Use an embedding model to calculate user intent, perform semantic matching at the gateway layer, and dynamically route the request to the most suitable upstream model service....
