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.

import sys
import chilkat2

success = False

success = False

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

ai = chilkat2.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).
ai.Provider = "openai"

# Use your provider's API key.
ai.ApiKey = "MY_API_KEY"

# Choose a model.
ai.Model = "gpt-5-mini"

# 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.
file_id = "file-5G2xncrEiHbVfYPRpFgP9c"
ai.InputAddFileId(file_id,"application/json")

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

# Ask the AI for text output.
success = ai.Ask("text")
if (success == False):
    print(ai.LastErrorText)
    sys.exit()

# Get the text response.
sbResponse = chilkat2.StringBuilder()
ai.GetOutputTextSb(sbResponse)
print(sbResponse.GetAsString())
