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. Visual Basic 6.0

' The provider can be "openai", "google", "claude", "grok", or any AI that supports uploading files for later reference by ID.

ai.ApiKey = "MY_API_KEY"

' We can upload directly from a file in the filesystem, or from a Chilkat StringBuilder, or from a Chilkat BinData.

' Some AI providers require a content-type.
' Also, some AI providers are picky about what content-type's are accepted.
' Check the AI provider's documentation.
' "application/json" is generally always acceptable.
' "text/plain" can be used as a fallback for any text file.
