How to upload files with the OpenAI API – Openai-api

The Problem:

Upload files to OpenAI API. The API documentation specifies a file parameter, but it is unclear how to include the actual file content when making the request.

The Solutions:

Solution 1: Using File Object in Node.js

For Node.js users, Open AI accepts a File object created using `new File()`. To upload a file using this method:

// Create a File object with the file content, name, and type
const file = new File([blob], 'example.txt', { type: 'text/plain' });

// Send the file to Open AI using the `files.create` method
const upload = await openai.files.create({
  file: file,
  purpose: "assistants",
});

Solution 2: Uploading Files with OpenAI API

To upload files using the OpenAI API, follow these steps:

1. Set your OpenAI API key using openai.api_key = os.getenv("OPENAI_API_KEY").

2. Create a file object using openai.File.create(). Pass the file path and purpose of the file (e.g., 'fine-tune'). The file parameter expects a file object, not a filename. Therefore, open the file in binary mode using open(filepath, "rb").

3. Store the response from openai.File.create() in a variable, as it contains the file_id and other information.

4. Use the file_id to create a fine-tuning job using openai.FineTuningJob.create(). Pass the file_id (results.id in the example code) and the desired model (config.BASE_MODEL in the example) as arguments.

5. Check the status of the fine-tuning job by retrieving it using openai.FineTuningJob.retrieve(results.id).

6. To obtain the generated model ID, monitor the status of the fine-tuning job until it completes using python train.py --state {results.id}.

Solution 3: File upload methods

To upload files using the OpenAI API, you have two options:

Using curl:

• Append the file information using the -F command followed by the filename/path.

Using Postman:

• In the Body tab, select "form-data" and change the "key" field from "Text" to "File". Click "Select File" to choose the file to upload.
• Alternatively, click "binary" and select the file.
