Routing Layers Turn Models Into Substitutable Components
Enterprises building on a single provider discovered the cost of that dependency early and responded by inserting a routing layer between their applications and any model. Around 56% of production deployments now call more than one provider, choosing by task, cost, latency or availability rather than by relationship. The consequence is that switching became configuration rather than migration, which removes the lock-in providers had assumed they were building. Inference serving and routing platforms grow at 24.0% as a direct result, and they capture margin the model layer is losing. Providers rarely discuss this development directly.
