Only supported by OpenAI GPT-5.6 and newer. | all\_turns | | `effort` | [models.ReasoningEffort](../models/reasoningeffort.mdx) | :heavy\_minus\_sign: | N/A | medium | | `mode` | [models.ReasoningMode](../models/reasoningmode.mdx) | :heavy\_minus\_sign: | Selects the reasoning mode. `standard` is the default; `pro` engages deeper reasoning on models that support it, billed at standard token rates. Only supported by OpenAI GPT-5.6 and newer. | standard | | `summary` | [models.ReasoningSummaryVerbosity](../models/reasoningsummaryverbosity.mdx) | :heavy\_minus\_sign: | N/A | auto | | `enabled` | *boolean* | :heavy\_minus\_sign: | N/A | | | `maxTokens` | *number* | :heavy\_minus\_sign: | N/A | |
