Improvements to the fine-tuning API and expanding our custom models program

🧀

OpenAI introduces new features to its fine-tuning API for developers, providing more control over model training, and expands its Custom Models Program to assist organizations in creating domain-specific AI models. Improvements include epoch-based checkpoint creation, comparative playground, third-party integration, and comprehensive validation metrics. They also offer assisted fine-tuning for organizations needing extra support and custom-trained models that infuse domain knowledge into AI.

  • Self-serve fine-tuning API launched for GPT-3.5 in August 2023.
  • Epoch-based checkpoints reduce need for retraining.
  • Third-party integration starts with Weights and Biases.
  • Assisted fine-tuning aids performance maximization.
  • Harvey's legal AI tool benefited from a custom model.
