function Start-TuneJob { <# .SYNOPSIS Initiates model tuning using a specified file ID. .DESCRIPTION This command accepts a file ID to start the model tuning process via a POST request to the OpenAI API. .PARAMETER FileId The file ID of the training file. This parameter allows manual specification of the file ID and can be piped in. .PARAMETER Model The model to be used for tuning. Default is 'gpt-3.5-turbo-0613'. Your custom models can be reused, fa sho. .PARAMETER WhatIf Shows what would happen if the cmdlet runs. The cmdlet is not run. .PARAMETER Confirm Prompts you for confirmation before running the cmdlet. .EXAMPLE Start-TuneJob -FileId file-g8qyzvm2hxPxK1iwVaTX6Z3E This example demonstrates manually specifying the file ID to initiate the model tuning process. .EXAMPLE Send-TuneFile -FilePath C:\path\to\file.json | Start-TuneJob -Model ft:gpt-3.5-turbo-0613:personal::8COaNMYp This example demonstrates piping the file ID to Start-TuneJob to initiate the model tuning process against a pre-trained custom model. .EXAMPLE Start-TuneJob -FileId file-g8qyzvm2hxPxK1iwVaTX6Z3E -WhatIf Shows what would happen if the cmdlet runs, but does not execute the cmdlet. .EXAMPLE Start-TuneJob -FileId file-g8qyzvm2hxPxK1iwVaTX6Z3E -Confirm Prompts for confirmation before executing the cmdlet. #> [CmdletBinding(SupportsShouldProcess, ConfirmImpact = 'Low')] param ( [Parameter(Mandatory, ValueFromPipelineByPropertyName)] [Alias("training_file", "Id")] [string[]]$FileId, [string]$Model = 'gpt-3.5-turbo-0613' ) process { foreach ($id in $FileId) { if ($PSCmdlet.ShouldProcess("File ID: $id for Model Tuning", 'Start')) { $body = @{ training_file = $id model = $Model } | ConvertTo-Json $params = @{ Uri = "https://api.openai.com/v1/fine_tuning/jobs" Method = "POST" Body = $body ContentType = "application/json" } Invoke-RestMethod2 @params } } } } |
