Why Use-Case Pages Beat Model-Specific Pages for SEO
Model names change every few months (GPT-4 → GPT-4o → GPT-4.1 → GPT-5). But search intent is durable: "best AI model for coding" and "AI API cost calculator" are evergreen queries that don't depend on a specific model name. This hub targets evergreen intent pages as the core, with individual model pages as supporting content fed from the centralized data source. When a new model launches, we update one JSON file and every use-case page automatically includes it.
