# Gateway Providers

Gateway providers aggregate multiple model providers and add features like caching, rate limiting, analytics, and automatic failover. Use gateways when you need observability, cost management, or simplified multi-provider access.

## Custom gateways

Create custom gateways for private LLM deployments or specialized provider integrations. See [Custom Gateways](https://mastra.zisheng.pro/en/models/gateways/custom-gateways) for implementation details.
