Summary

In this chapter, we discussed the concept of fine-tuning within the ChatGPT API, exploring how it can help us to tailor ChatGPT API responses to our specific needs. By training a pre-existing language model on a diverse dataset, we enhanced the gpt-3.5-turbo model performance and adapted it to a particular task and domain. Fine-tuning enriched the model’s capacity to generate accurate and contextually fitting responses by incorporating domain-specific knowledge and language patterns. Throughout the chapter, we covered several key aspects of fine-tuning, including the available models for customization, the associated costs, data preparation using JSONL files, the creation of fine-tuned models, and the utilization of these models with the ChatGPT API. We underscored the significance of fine-tuning to achieve superior outcomes, reduce token consumption, and enable faster and more responsive interactions.
