# 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

```typescript theme={null}
import { ReasoningContext } from "@openrouter/sdk/models";

let value: ReasoningContext = "all_turns";

// Open enum: unrecognized values are captured as Unrecognized<string>
```

## Values

```typescript theme={null}
"auto" | "all_turns" | "current_turn" | Unrecognized<string>
```
