# Control & Data Plane

## Terminology

| **Term**          | **Description**                                                                                                                |
| :---------------- | :----------------------------------------------------------------------------------------------------------------------------- |
| **Template**      | A deployable performance “blueprint” for a model. Templates define which `flavor_name`, `gpu_type`, and regions are supported. |
| **Flavor**        | A template's sub-option (e.g. `base`, `fast`) with different performance/throughput/costs characteristics.                     |
| **Endpoint**      | Dedicated deployment with API access                                                                                           |
| **endpoint\_id**  | Identifier used for update/delete operations.                                                                                  |
| **routing\_key**  | The model identifier you pass to inference calls. Returned when you create an endpoint.                                        |
| **Control plane** | Sets up the configuration and settings of your endpoints. Has common base URL API.                                             |
| **Data plane**    | Processes model inference requests. Has regional base URL API.                                                                 |

## Control plane

Dedicated Endpoints Control Plane is a managedment layer for all configurations operations:

* Creating & updating endpoints
* Uploading models / weights
* Scaling configs (min/max replicas)
* Monitoring setup

Use common base URL API for all dedicated endpoint management operations:

```text theme={null}
https://api.tokenfactory.nebius.com
```

## Data plane

Dedicated Ednpoints Data Plane processes model inference requests. It has regional base URL API. Region impacts latency, data locality, and regulatory compliance.

Use a region-appropriate base URL for your inference calls:

| Endpoint region | Inference base URL                                |
| :-------------- | :------------------------------------------------ |
| `eu-north1`     | `https://api.tokenfactory.nebius.com`             |
| `eu-west1`      | `https://api.tokenfactory.eu-west1.nebius.com`    |
| `us-central1`   | `https://api.tokenfactory.us-central1.nebius.com` |

<Note>
  Using the respective inference base URL avoids unnecessary global routing and reduces round-trip latency.
