OpenAI has just announced the exciting release of fine-tuning capabilities for GPT-3.5 Turbo, with GPT-4's fine-tuning coming in the fall (although the exact date still isn't known).

This groundbreaking update allows developers to create tailored models that achieve superior performance for specific tasks, further elevating the potential for AI-driven products & solutions. GPT-3.5-Turbo can be as effective as GPT-4 now, and it's much cheaper than before.

Highlights from the Release:

  • Enhanced Performance: Preliminary tests reveal that fine-tuned GPT-3.5 Turbo models can match or even surpass base GPT-4 capabilities in specialized tasks.
  • Diverse Customization Options: Developers now enjoy increased steerability, dependable output formatting, and the ability to refine the model’s tone, ensuring consistency with brand voices.
  • Economical and Efficient: Fine-tuning can decrease prompt sizes by up to 90%, leading to faster API calls and reduced costs.
  • Safety First: OpenAI remains committed to safety. All data used for fine-tuning is meticulously vetted through their Moderation API and a GPT-4 powered system to ensure it meets OpenAI's rigorous safety standards.
  • Transparent Pricing: Fine-tuning costs have been detailed, allowing businesses to forecast expenses accurately.
  • New GPT-3 Model Updates: As part of a broader move, OpenAI announced the release of the babbage-002 and davinci-002 models as replacements for the original GPT-3 models, further enriching the range of tools available to developers.

OpenAI's commitment to enabling unique, customizable capabilities with ChatGPT are even more evident with this release. As developers across the globe have clamored for the ability to refine the model for their specific needs, this launch marks a significant step forward in the Post-ChatGPT AI world.

Previously, the only way to do this was training a completion model (not a ChatGPT one). You could also provide ChatGPT custom instructions, but it wasn't the same thing.

The company is also looking forward to debuting a user-friendly fine-tuning UI soon, further simplifying the process for developers. With easy-to-follow steps for fine-tuning and robust support, OpenAI aims to streamline the developer experience and encourage more customized AI applications across industries.

To delve deeper into the world of fine-tuning and access the newly available features, developers are encouraged to visit the OpenAI fine-tuning documentation (as tweeted by Paul Graham.)

Founded in 2015, OpenAI (the creators of ChatGPT) is a leading force in artificial intelligence research and deployment. With a mission to ensure that artificial general intelligence (AGI) benefits all of humanity, OpenAI consistently breaks new ground in the field, bringing state-of-the-art solutions to developers and businesses worldwide.
