| ----------- | --------------------------------------------------------------------------------------------------------------------------------- | -------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------- |
| `Context`   | optionalnullable.OptionalNullable\[[components.ReasoningContext](../../models/components/reasoningcontext.mdx)]                   | :heavy\_minus\_sign: | 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. | all\_turns |
| `Effort`    | optionalnullable.OptionalNullable\[[components.ReasoningEffort](../../models/components/reasoningeffort.mdx)]                     | :heavy\_minus\_sign: | N/A                                                                                                                                                                                                                                                                  | medium     |

Only supported by OpenAI GPT-5.6 and newer.                                                                         | standard   |
