What problem does it solve?
Customizing and deploying foundation models on AWS involves many decisions — choosing a base model, picking a fine-tuning technique, validating datasets, generating training code, and managing endpoints. This Skill guides AI coding agents through the entire SageMaker model customization lifecycle with validated workflows, so nothing critical gets missed.
Core Features & Use Cases
- Model Selection & Planning: Discover models from SageMaker Hub, define use case specs, and build step-by-step customization plans (fine-tune, evaluate-first, or deploy base model).
- Fine-Tuning & Data Preparation: Generate training code for SFT, DPO, RLVR, and RLAIF techniques; validate and transform datasets into required JSONL formats.
- Evaluation, Deployment & Diagnostics: Evaluate models with LLM-as-Judge or Custom Scorers, deploy to SageMaker endpoints or Bedrock, manage MLflow apps, and diagnose endpoint failures with CloudWatch metrics and logs.
- Use Case: A developer wants to fine-tune a Llama model on their customer support data. The Skill helps them select the model, validate their dataset, generate the SFT training script, evaluate the result, and deploy it to a SageMaker endpoint.
Quick Start
Ask the agent to help you fine-tune a model on SageMaker, for example: "Help me fine-tune a Qwen model on my dataset and deploy it to a SageMaker endpoint."
