Dynamic Model Router

"""
This example demonstrates how to use dynamic model router with OpenRouter.

Dynamic models provide automatic failover when the primary model encounters:
- Rate limits
- Timeouts
- Unavailability
- Model overload

OpenRouter will automatically try the models defined in order until one succeeds.
