# UpdateRerankerRequestBase - `displayName` (`string | null`, optional): User-facing name of the reranker - `description` (`string | null`, optional): Description of the reranker - `endpointUrl` (`string | null`, optional): API endpoint URL - `apiPath` (`string | null`, optional): API path for reranking request - `modelIdentifier` (`string | null`, optional): Model identifier - `supportedModalities` (`Array | null`, optional): Update supported modalities (if array contains >=1 elements, replaces stored set; if empty or omitted, no change and does not count as an update by itself) - `credentials` (`EndpointAuthentication | null`, optional): Replace stored credentials. Omit this field to preserve the current credentials; a present empty payload is invalid and never clears them. - `replaceLabels` (`Record | null`, optional): Replace all existing labels with these (mutually exclusive with mergeLabels) - `mergeLabels` (`Record | null`, optional): Merge these labels with existing ones (mutually exclusive with replaceLabels) - `version` (`string | null`, optional): Version information - `monitoringEndpoint` (`string | null`, optional): Monitoring endpoint URL - `dashscopeApiDialect` (`DashScopeApiDialect | null`, optional): Update the DashScope request and response API dialect. Valid only for the DASHSCOPE provider. Omit to preserve the stored dialect. Changing apiPath to a recognized canonical DashScope dialect infers its matching dialect; a custom path preserves an existing dialect, while a legacy null dialect is inferred. Allowed values for this field: RERANK_NATIVE_NESTED, RERANK_COMPATIBLE_FLAT.
