Building a model that works in a Jupyter notebook is only 20% of the ML lifecycle. Production ML requires robust data pipelines, model versioning, monitoring, and continuous retraining — all while maintaining low latency and high availability.
Training-serving skew, silent data drift, and unmonitored model decay are the top reasons ML projects fail in production. Invest in observability from day one and establish clear rollback procedures.
Traditional ML excels at structured prediction (churn, fraud, demand forecasting). LLMs excel at unstructured language tasks. Many modern products combine both — ML for scoring and routing, LLMs for generation and reasoning.
