Not degraded.
Not more expensive.
Gone.
A lot of teams spend months optimizing prompts, evaluations, and workflows around a single model.
But here's the real question:
What happens when that model is no longer available?
Most AI systems are built around a model.
The best AI systems are built around an interface.
When Claude, GPT, Gemini, or an open-source model changes, gets restricted, or becomes unavailable, resilient systems can switch providers without rebuilding the entire stack.
That's why I'm seeing more teams move toward:
• Multi-model architectures• Provider abstraction layers• Model fallback strategies• Evaluation-driven model selection
The future isn't choosing the perfect model.
It's building systems that survive when the perfect model changes.
Are you building model-dependent systems or model-resilient systems?
