How to Fine-Tune Zephyr-7B for Support Call Analysis

Leveraging open-source Large Language Models (LLMs) can significantly reduce the costs associated with customer support calls by automating the classification of customer issues, a task traditionally prone to errors and resource-intensive when performed manually. This tutorial demonstrates how to fine-tune an open-source LLM, specifically Zephyr-7B-Beta, to accurately predict Task Types from customer support requests, using a rich dataset of voice call transcripts. By employing tools like Ludwig, an open-source AI model framework, and Predibase, a managed AI platform, users can streamline the fine-tuning process on specialized datasets, resulting in improved accuracy and efficiency in identifying customer needs. These techniques not only enhance customer service by providing actionable insights for self-service improvements but also lower operational costs for support centers. The tutorial provides step-by-step instructions for setting up the environment, preparing data, and running experiments, showcasing that fine-tuned models can achieve a higher accuracy rate compared to the untrained models.
