Amazon Web Services has released a practical guide detailing how to fine-tune its Nova models using the Nova Forge SDK. This second part of a series focuses on data mixing, a technique that allows for domain-specific customization without degrading general capabilities. The guide provides a step-by-step walkthrough covering environment setup, data preparation, training configuration with SageMaker HyperPod, model training using LoRA, and evaluation against benchmarks. This approach aims to offer a repeatable playbook for developers to adapt to their specific use cases, contrasting with methods that can lead to a loss of general abilities when fine-tuning on limited datasets.
