AWS offers an 8-step decision framework for generative AI customization, starting from prompt engineering to training custom models. Most workloads only need steps 1-3: using existing models (Amazon Bedrock), optimizing prompts, and retrieval-augmented generation (RAG). Model distillation can reduce costs by up to 75% with less than 2% accuracy loss. Fine-tuning options include Parameter-Efficient Fine-Tuning (PEFT/LoRA) and Full Fine-Tuning, with Reinforcement Fine-Tuning (RFT) available for Amazon Nova models since December 2025.
