# Welcome to Verlon AI

> The AI Gateway for production applications - route, fallback, and track costs across multiple AI providers

## What is Verlon AI?

Verlon AI is an AI gateway that sits between your application and AI providers (OpenAI, Anthropic, Google, etc.). It provides intelligent routing, automatic fallbacks, cost tracking, and a unified API across all providers.

**Key benefits:**

* **Smart Routing** - Automatically route requests to the best model for each task
* **Automatic Fallbacks** - Never fail when a model is down
* **Cost Tracking** - Real-time cost analytics per request, user, and endpoint
* **Unified API** - One interface for GPT, Claude, Gemini, Mistral, and more
* **Drop-in Replacement** - Works with OpenAI SDK and Anthropic SDK
