 ## Planned Changes
 
-None.
+- [PLANNED: OLS-3442] Add `reasoningConfig` field (`map[string]interface{}`) to `ModelParametersSpec`. Freeform map passed through to the service as `reasoning_config` for provider-specific reasoning/thinking parameters. Includes release notes and user-facing documentation for valid keys per provider.
