 To set up multiple LLM endpoints, use the `ai.routes` field in the `policies` section of the {{< reuse "agw-docs/snippets/backend.md" >}} resource. This field maps the API paths to supported route types. The keys are URL suffix matches, like `/v1/models`. The values are the route types, like `Completions` or `Passthrough`.
 
-Alternatively, you can define the routes in a separate {{< reuse "agw-docs/snippets/policy.md" >}} resource attached to an {{< reuse "agw-docs/snippets/agentgateway.md" >}} {{< reuse "agw-docs/snippets/gateway-api.md" >}}. This approach decouples routing configuration from the backend definition, which can simplify management when you have multiple routes pointing to the same backend.

 - `Completions`: Parses the request, translates it to the LLM provider format, and fully processes it as an LLM request. This route type unlocks the full set of {{< reuse "agw-docs/snippets/agentgateway.md" >}} LLM features, such as tokenization and token-based rate limiting, prompt guards, prompt enrichment, model aliasing, transformations, cost tracking, and detailed observability.
 - `Detect`: Forwards the request as-is, but makes a best effort to extract the model and token counts so that a subset of policies still applies, specifically token-based rate limiting and telemetry. Guardrails and other request-shaping policies do not apply. Use this route type for endpoints with a format that cannot be automatically parsed by {{< reuse "agw-docs/snippets/agentgateway.md" >}}, but where you still want metrics and rate limiting.
