How to choose AI providers without creating lock-in
A practical framework for separating the durable workflow from the models and platforms that may change underneath it.
Start with the workflow contract
Provider independence begins before vendor selection. Define the workflow in terms of its inputs, outputs, users, decisions, exceptions, latency, quality threshold, and business metric. That contract should remain stable even when the underlying model changes.
When the provider becomes the architecture, every improvement becomes a migration. When the workflow is the architecture, providers become replaceable components.
Evaluate systems, not leaderboard scores
A model benchmark is not a production benchmark. Test the complete path: retrieval, tools, permissions, structured outputs, human review, latency, failure handling, and cost at the expected volume.
The best result may use different providers for reasoning, voice, image, search, and infrastructure. Independence means preserving that option without forcing the customer to operate the complexity alone.
Design the exit before launch
Store prompts, evaluations, business rules, and workflow state outside provider-specific interfaces where practical. Establish export paths, fallback behavior, and acceptance tests before production. A provider change should be an engineering decision, not a corporate restart.
