## Runner

Source: [src/cwsandbox/\_discovery.py:128](https://github.com/coreweave/cwsandbox-client/blob/v0.22.0/src/cwsandbox/_discovery.py#L128)

```python theme={"system"}
class Runner(*, runner_id: str, runner_group_id: str, tags: tuple[str, ...], healthy: bool, profile_names: tuple[str, ...], connected_at: datetime, max_cpu_millicores: int, max_memory_bytes: int, max_gpu_count: int, supported_gpu_types: tuple[str, ...], supported_architectures: tuple[str, ...], supports_privileged: bool, available_storage_classes: tuple[str, ...], resources: RunnerResources | None = None)
```

A runner registered with the discovery service.

Runners are the compute nodes that run sandboxes. Each runner advertises
its capabilities (CPU, memory, GPU) and the profiles it supports.

**Attributes**

* `resources` (`RunnerResources | None`): Live resource availability, or `None` if not reported.

## RunnerResources

Source: [src/cwsandbox/\_discovery.py:111](https://github.com/coreweave/cwsandbox-client/blob/v0.22.0/src/cwsandbox/_discovery.py#L111)

```python theme={"system"}
class RunnerResources(*, available_cpu_millicores: int, available_memory_bytes: int, available_gpu_count: int, running_sandboxes: int)
```

Live resource availability for a runner.

## Profile

Source: [src/cwsandbox/\_discovery.py:192](https://github.com/coreweave/cwsandbox-client/blob/v0.22.0/src/cwsandbox/_discovery.py#L192)

```python theme={"system"}
class Profile(*, profile_name: str, runner_id: str, supported_gpu_types: tuple[str, ...], supported_architectures: tuple[str, ...], service_exposure_modes: tuple[ServiceExposureMode, ...], egress_modes: tuple[EgressMode, ...])
```

A profile configuration on a specific runner.

Profiles define execution environments with specific service exposure modes, egress modes, and hardware capabilities.

***

## ServiceExposureMode

Source: [src/cwsandbox/\_discovery.py:89](https://github.com/coreweave/cwsandbox-client/blob/v0.22.0/src/cwsandbox/_discovery.py#L89)

```python theme={"system"}
class ServiceExposureMode(*, name: str)
```

A service exposure mode supported by a profile.

***

## EgressMode

Source: [src/cwsandbox/\_discovery.py:100](https://github.com/coreweave/cwsandbox-client/blob/v0.22.0/src/cwsandbox/_discovery.py#L100)

```python theme={"system"}
class EgressMode(*, name: str)
```

An egress mode supported by a profile.
