# Container - Go SDK

> Container type definition

<Warning>
  The Go SDK and docs are currently in beta.
  Report issues on [GitHub](https://github.com/OpenRouterTeam/go-sdk/issues).
</Warning>

## Supported Types

###

```go lines theme={null}
container := components.CreateContainerStr(string{/* values here */})
```

### ContainerAuto

```go lines theme={null}
container := components.CreateContainerContainerAuto(components.ContainerAuto{/* values here */})
```

## Union Discrimination

Use the `Type` field to determine which variant is active, then access the corresponding field:

```go lines theme={null}
switch container.Type {
	case components.ContainerUnionTypeStr:
		// container.Str is populated
	case components.ContainerUnionTypeContainerAuto:
		// container.ContainerAuto is populated
}
```
