# 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

```python theme={null}
from openrouter.components import ReasoningContext

# Open enum: unrecognized values are captured as UnrecognizedStr
value: ReasoningContext = "auto"
```

## Values

This is an open enum. Unrecognized values will not fail type checks.

* `"auto"`
* `"all_turns"`
* `"current_turn"`
