# Routing

https://modelportal.ai/docs/routing

A model usually has offers from several providers. This group explains how the platform chooses among endpoints and how you can steer it:

- [Provider selection](/docs/provider-routing): the `provider` parameter, locking to an endpoint, and differences from OpenRouter.
- [Fallbacks](/docs/fallbacks): what `allow_fallbacks` means and its default.
- [Default routing](/docs/default-routing): ordering, traffic splitting and session stickiness when you set nothing.
- [Data policy](/docs/data-policy): endpoint data policy declarations, `data_collection` and data processing regions.
- [Budgets and limits](/docs/budgets): balance, key spend limits, rate limits and price caps.
