A `search_*` value narrows the response to search results only; a classic value narrows the OpenRouter items and leaves other sources' items as they are. ## Example Usage ```go theme={null} import ( "github.com/OpenRouterTeam/go-sdk/models/operations" ) value := operations.BenchmarkTypeGpqaDiamond // Open enum: custom values can be created with a direct type cast custom := operations.BenchmarkType("custom_value") ``` ## Values | Name | Value | | -------------------------------------- | ----------------------------- | | `BenchmarkTypeGpqaDiamond` | gpqa\_diamond | | `BenchmarkTypeTauBenchVerifiedAirline` | tau\_bench\_verified\_airline | | `BenchmarkTypeSearchBrowsecomp` | search\_browsecomp | | `BenchmarkTypeSearchHle` | search\_hle | | `BenchmarkTypeSearchDsqa` | search\_dsqa | | `BenchmarkTypeSearchWidesearch` | search\_widesearch |
