(VBScript) Upload a File to an AI Provider (OpenAI, Google, Antropic, X)

See more AI Examples

Uploads a file to an AI provider using the provider's File API and returns the id that can later be used to reference the file in an query. This currently works with ChatGPT, Gemini, Claude, and Grok.

Note: This example requires Chilkat v11.4.0 or greater.
