Hello,

The code

       Dim getTool = ResponseTool.CreateComputerTool(ComputerToolEnvironment.Browser, 1280, 720)
       options.Tools.Add(getTool)

injects the old json value “computer_user_preview” value instead of “computer”, raising the error:

System.ClientModel.ClientResultException: 'HTTP 400 (invalid_request_error: )
Parameter: tools

Tool ‘computer_use_preview’ is not supported with gpt-5.4.’

Am I right?

Thank You
