Every few months the frontier moves: a new model writes better, reasons deeper, or costs a tenth as much. If your brand operation is welded to one vendor, every one of those moves is either a migration project or a missed advantage.
Separate the layers.
The architecture that survives is layered: the brand layer — voice rules, business logic, decision rights, institutional memory — sits above the model layer. Models become interchangeable engines underneath. When a stronger model ships, the system routes the right tasks to it and nothing about your brand logic changes. The work compounds; the vendor dependency does not.
Routing by task, not by loyalty.
In production, different work wants different engines. Frontier models for strategy and long-form judgment. Fast models for scoring and classification at volume. Vision models for creative review. Routing this way cuts cost dramatically — our flagship deployment ran 44,000+ operations for under fifty dollars — and it means a price change or an outage at any one vendor is an inconvenience, not an incident. The numbers are public on the case study.
The questions to ask any vendor.
Can the system swap models without rework? Who owns the prompts, the memory, and the configurations? What happens to the institutional memory if you leave? Our answers: yes, you, and it leaves with you — the full stack hands off, no lock-in. The model-routing layer is one of seven described on the system page.
