0 views

This notebook is your essential toolkit for preprocessing and analyzing chat datasets before fine-tuning chat models. It detects format errors, delivers key statistics, and estimates token counts to predict costs accurately. Designed for the latest gpt-3.5-turbo fine-tuning method—see legacy docs for babbage-002 and davinci-002.

This notebook functions as a comprehensive utility for preprocessing and analyzing the chat dataset utilized in fine-tuning a chat model.

It identifies format errors, delivers essential statistics, and estimates token counts to forecast fine-tuning costs.

The techniques presented here align with the current fine-tuning process for gpt-3.5-turbo.

See legacy fine-tuning for models like babbage-002 and davinci-002.
