OpenRouter gives apps one AI gateway

OpenRouter is less a model vendor than a portability layer, and that makes it unusually practical for fast-moving AI apps.

• –One API surface means teams can swap between OpenAI, Anthropic, Google, Mistral, and others without reworking core app code.
• –Auto-routing and fallback support turn model choice into an operational setting instead of a permanent product bet.
• –The OpenAI-compatible request format lowers adoption friction for developers already shipping chat-completion flows.
• –For builders stitching together Convex, Stripe, Vercel, and an LLM layer, OpenRouter is valuable because it simplifies experimentation while keeping provider lock-in lower.
