Building on Quicksand: Why AI Model Churn Forces Architectural Rethink

The rapid release and deprecation cycles of frontier AI models—compressing from 37-day intervals in 2023 to even tighter schedules—are creating existential risks for teams locked into specific model behaviors. With deprecation windows as short as 60 days and entire platforms like OpenAI's Assistants API facing complete sunset, architects must design for model independence rather than optimizing for today's capabilities. Winners will treat AI models as interchangeable commodities, not foundational platforms.
