The Fragility of Direct Integrations

Companies are increasingly integrating LLMs into their applications. But direct API connections create severe technical debt and operational risk.

Models evolve quickly, providers change prices overnight, and API endpoints depreciate. Switching models traditionally requires time-consuming deployments, system interruptions, and high development costs.

LLM Hot-Swapping with ONE

With ONE Middleware, the language model is decoupled from the application. The application now communicates only with ONE.
