# Models & providers

Three short pages on the routing layer:

- [Available models](available) — what's on the platform, how to
  read the model browser, and the IDs you'll use in requests.
- [Routing](routing) — what `lowrouter/auto` does, how ties are
  broken, and what overrides do what.
- [Per-request metadata](per-request-metadata) — the `lowrouter`
  block on every response, field by field.

The dashboard's [model browser](/models) is the live, searchable view
of the same data.
