Fine-Tuning GPT 3.5 with Unstructured: A Comprehensive Guide

Advancements in large language models (LLMs) like OpenAI's GPT-3, 3.5, and 4 have democratized access to high-powered language processing, yet they remain limited by static knowledge bases and cutoff dates, such as GPT's knowledge ending in September 2021. To address these limitations and enhance relevance in specific domains or with updated data, organizations are using techniques like fine-tuning and Retrieval Augmented Generation (RAG). Fine-tuning allows models to encode specialized knowledge directly, while RAG provides access to new information. The article discusses utilizing the Unstructured platform to integrate the latest data into models like ChatGPT, enhancing functionality through Google Cloud and Python tools. It details the process of preparing a dataset, fine-tuning models with OpenAI's API, and highlights the challenges and benefits of this approach, including improved accuracy and relevance over default models. The piece concludes by recommending a combination of fine-tuning and RAG for optimal results and hints at further exploration of these techniques in an upcoming blog post.
