What does responsible deployment with human oversight look like in practice?

It means designing the whole lifecycle, not just the model, for accountability. Before launch: define intended use and out-of-scope use, evaluate on representative and edge-case data, red-team for misuse, and document with a model card. At deployment: match the oversight level to risk — human-in-the-loop (a person approves each decision) for high-stakes actions, human-on-the-loop (monitoring with ability to intervene) for lower-stakes automation, and clear escalation paths. Add guardrails, rate limits, logging, and the ability to roll back. After launch: monitor for drift, disparate impact, and abuse; collect feedback; and keep a named owner accountable. The point of oversight is that a human can meaningfully understand and override the system — rubber-stamping automated outputs doesn't count.
