Field	Type	Required	Description	Example
`defaultEffort`	models.DefaultEffort	➖	N/A	medium
`defaultEnabled`	boolean	➖	Default reasoning enabled state when the client does not set `reasoning.enabled`.
`mandatory`	boolean	✔️	When true, reasoning cannot be disabled and effort “none” is rejected.
`supportedEfforts`	models.ReasoningEffort[]	➖	Allowed reasoning effort values for this model, in descending effort order (highest first). Null means no allowlist — all gateway effort values are accepted.
`supportsMaxTokens`	boolean	➖	Present and `true` when the model accepts `reasoning.max_tokens` in requests (Anthropic-style) instead of or in addition to `reasoning.effort`. Omitted otherwise.
