Dependency is not about using an API. It is about your architecture speaking only one vendor.
Orchestration is the layer that decides, per call, which model responds. It routes by task, cost, privacy and availability. And it lets you switch from OpenAI to Anthropic or Google, or move a piece to a local model, without rewriting the system your team uses.
Six functions that turn LLM calls into an operable layer
- 01
Routing by task
Each task has a default model. Configuration lives in a system file, not in every call. Changing a task's default is one line, not a refactor.
- 02
Fallback and retry
When the primary provider fails or hits rate limits, the call drops to a secondary automatically. Operations keep running while platform looks into it.
- 03
Cost control
Budget per client, per project or per endpoint. Alerts when something spikes. Never a surprise invoice at month end.
- 04
Traceability and audit
Every call is logged with the chosen model, the response, the cost and the time. Auditing means opening a log, not re-running the pipeline.
- 05
Provider switch
When a provider deprecates a model, raises prices or enters tricky regulatory ground, a piece moves to the competitor. No migration, no pain.
- 06
Privacy by default
Endpoints with contracted no-retention. EU regions. Sensitive data never reaches the wrong provider. Policy is declared, the gateway enforces it.
Every SVP implementation includes a configured model gateway
It is not optional. It is what guarantees the system survives changes in the model market without you having to rewrite anything.
