    client: &OpenAIClient,
    file_path: &Path,

The purpose is required by the API.

Parameters

• client - The OpenAI client.
• file_path - Path to the local file to upload.
• purpose - The file’s intended usage (e.g. UploadFilePurpose::FineTune).

Returns

A FileObject containing metadata about the newly uploaded file.

Errors
