TL;DR

To fine-tune OpenAI’s GPT-3.5 Turbo:

  1. Prepare Data: Format data as a series of interactions between the system, user, and assistant.
  2. Upload Files: Use a curl command to send your data to OpenAI's API.
  3. Initiate Fine-Tuning: Send another curl command using the uploaded data to start the fine-tuning process.
  4. Use Fine-Tuned Model: Once done, use the fine-tuned model by sending a request to OpenAI’s chat completions endpoint.

This process customizes the GPT-3.5 Turbo model for specific tasks using your own data. For more information, you can read this post for Python implementation and full details or check out the OpenAI announcement:
