# Routing & reliability

## Docs

- [Routing & passthrough](https://respan.ai/docs/documentation/features/gateway/routing-and-passthrough.md): Pick an endpoint, and see how Respan chooses the model, provider, and key for each request.
- [Retries and fallback](https://respan.ai/docs/documentation/features/gateway/retries.md): Retry a failed call on the same model, then try other models in order.
- [Load balancing](https://respan.ai/docs/documentation/features/gateway/load-balancing.md): Split traffic across your provider keys, or across models, by weight.
