OpenAI brings fine-tuning to GPT-3.5 Turbo | TechCrunch

Aug 22, 2023 - techcrunch.com
OpenAI has updated its GPT-3.5 Turbo model to allow customers to bring custom data for fine-tuning, improving the AI model's reliability and specificity. The company claims that these fine-tuned versions can match or even surpass the capabilities of their flagship model, GPT-4, in certain tasks. Fine-tuning enables users to customize the model's responses, improve its consistency, and reduce text prompt size to speed up API calls and reduce costs.

In addition, OpenAI has released two updated GPT-3 base models and plans to retire the original ones by January 2024. The company also announced that fine-tuning support for GPT-4, which can understand both text and images, will be available later this fall. However, no specific timeline was provided for this update.

Key takeaways:

  • OpenAI customers can now bring custom data to the lightweight version of GPT-3.5, GPT-3.5 Turbo, improving the AI model’s reliability and specific behaviors.
  • Fine-tuning allows companies to make the model follow instructions better, improve the model’s ability to consistently format responses, and hone the model’s output to better fit a brand or voice.
  • OpenAI plans to launch a fine-tuning UI in the future with a dashboard for checking the status of ongoing fine-tuning workloads.
  • OpenAI has made available two updated GPT-3 base models (babbage-002 and davinci-002), and plans to retire the original GPT-3 base models on January 4, 2024.
