The valuable abstraction is a stable conversation service, not an API that leaks the implementation details of its current model pipeline.
HTTP contract
Define requests, responses, errors, authentication, and timeouts independently from the model library.
Orchestration layer
Prompt chains, memory, model selection, and tool calls can remain behind the service boundary.
Deployment surface
A running service needs configuration, logging, health behavior, and persistence choices that are not owned by the UI.
Replacement test
A new backend should satisfy the same contract and pass the same quality and reliability checks before it becomes a production replacement.
