  • The OpenAI Fine-Tuning API is a service that allows developers to customize the models available through the OpenAI API by providing their own data and training objectives. Fine-tuning can improve the quality, reliability, and efficiency of the models for specific applications. For example, you can fine-tune a model to generate product descriptions, summaries, captions, or any other text-based task.
  • Some of the features and benefits of the OpenAI Fine-Tuning API are:
    • You can use any existing dataset of virtually any shape and size, or incrementally add data based on user feedback.
    • You can choose from different models to fine-tune, such as gpt-3.5-turbo-0613 (recommended), babbage-002, or davinci-002. Fine-tuning for GPT-4 is expected to be available later this year.
    • You can use the same API endpoints and parameters to interact with your fine-tuned models as you do with the standard models.
    • You can save costs and tokens by using shorter prompts and getting faster responses from your fine-tuned models.
    • You can monitor the progress and performance of your fine-tuning jobs and deployments through the OpenAI Dashboard or the Azure OpenAI Service.
  • To get started with fine-tuning, you need to:
    • Prepare and upload your training and validation data in JSONL format.
    • Create a fine-tuning job with your desired model, data, and hyperparameters.
    • Deploy your fine-tuned model and use it for inference.
