Xbase++ Requires Chilkat v11.4.0+

Referencing a Pre-Uploaded File by file_id in an AI Request

See more AI Examples

Some AI proviers have a Files API that lets you upload content once and then reference it later in generation requests using a file_id. This is especially useful for large documents, reuse across multiple prompts, or keeping inputs structured and separate from your prompt text.

This example demonstrates how to use a file_id in a request.

LOCAL oAi
LOCAL cFile_id
LOCAL oSbResponse

nSuccess := 0

nSuccess := 0

//  This example assumes the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

oAi := CreateObject("Chilkat.Ai")

//  The provider can be "openai", "google", "claude", "mistral", "deepseek", "xai", or any provider
//  that supports referencing pre-uploaded files by a file_id (or file uri).
oAi:Provider := "openai"

//  Use your provider's API key.
oAi:ApiKey := "MY_API_KEY"

//  Choose a model.
oAi:Model := "gpt-5.6-luna"

//  See the following example showing how to upload a file
//  Upload a File to an AI Provider (OpenAI, Google, Antropic, X)

//  Use the file_id of the pre-uploaded file.
cFile_id := "file-5G2xncrEiHbVfYPRpFgP9c"
oAi:InputAddFileId(cFile_id, "application/json")

oAi:InputAddText("Explain why Hamlet delays taking revenge, using only evidence from the file.")

//  Ask the AI for text output.
nSuccess := oAi:Ask("text")
IF (nSuccess == 0)
    ? oAi:LastErrorText
    oAi:destroy()
    RETURN
ENDIF

//  Get the text response.
oSbResponse := CreateObject("Chilkat.StringBuilder")
oAi:GetOutputTextSb(oSbResponse)
? oSbResponse:GetAsString()

oAi:destroy()
oSbResponse:destroy()
