# ReasoningContext

Controls which reasoning is available to the model. `auto` uses the model default (same as omitting); `all_turns` includes reasoning from earlier turns passed in input; `current_turn` limits to the current turn only. Only supported by OpenAI GPT-5.6 and newer.

## Example Usage

```go theme={null}
import (
	"github.com/OpenRouterTeam/go-sdk/models/components"
)

value := components.ReasoningContextAuto

// Open enum: custom values can be created with a direct type cast
custom := components.ReasoningContext("custom_value")
```
