What problem does it solve? It guides the full machine-learning lifecycle so models are built on trustworthy data, evaluated against representative and adversarial cases, and deployed with monitoring instead of shipping untested experiments. ## Core Features & Use Cases - Data-to-Model Lifecycle: Covers dataset strategy, leakage checks, baselines, experiment tracking, and reproducible model versioning. - LLM and Retrieval Engineering: Supports fine-tuning decisions, embeddings, retrieval, reranking, and hybrid search for generative-AI applications. - Evaluation and Serving: Designs evaluation reports, error analysis, inference optimization, and monitoring for drift, latency, cost, and safety. - Use Case: When building a RAG-based support chatbot, use this Skill to compare prompting versus fine-tuning, design an evaluation set, and package inference behind a stable interface with fallbacks. ## Quick Start Ask the AI to act as an ML engineer and design an evaluation and deployment plan for your model or LLM application.
