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"`
