Model Abstraction Layer
A software architecture pattern that introduces an intermediate layer between business code and specific model APIs, centralizing model selection, prompt construction, and request dispatch logic in order to reduce migration costs.

Building a model abstraction layer can reduce the cost of switching models from "changing the whole site" to "changing one configuration."
With multiple models now available, product teams need to build a switchable model abstraction layer and base decisions on real tasks rather than public leaderboards.
Model abstraction layers (such as LangChain, LiteLLM, etc.) have emerged in the industry, shielding the API differences of different vendors through a unified interface.
Model abstraction layers can only solve the call format problem and cannot smooth over the differences between models in output style, context window, function-calling capability, and error code semantics.
Ayraix recommends maintaining a model abstraction layer and pinning model versions in configuration, rather than hard-coding model names in application code.
A model abstraction layer is a software architecture pattern that inserts an indirect interface between an application and a specific large model, so that switching models requires only modifying configuration and running regression tests.
A model abstraction layer is a software architecture design pattern that inserts an intermediate layer between application logic and underlying model APIs, uniformly encapsulating API call formats from different vendors so that upper-layer applications can call different models through a unified interface
Over-reliance on a single model vendor carries significant business risk, and adopting a model abstraction layer design allows flexible switching between different vendors to reduce supply chain risk
