Model deprecation and sunset criteria
Model deprecation and sunset criteria refer to the guidelines and processes for phasing out or discontinuing a machine learning model or software system. Deprecation involves formally announcing that a model is outdated or will no longer be supported, while sunset criteria define the specific conditions or timelines under which the model will be fully retired. These criteria help organizations ensure a smooth transition to newer models, maintain system reliability, and manage risks associated with outdated technologies.

💡 Key Takeaways
- Distinguish model deprecation from sunset and why governance treats them as related but distinct.
- Identify triggers for retirement, such as performance drift, regulatory constraints, cost, risk, or obsolescence.
- Learn to plan and execute a deprecation with timelines, stakeholder roles, and migration paths to replacements.
- Understand sunset criteria, including performance thresholds, data drift, maintenance costs, and availability of a replacement.
- Plan retirement logistics: communicate with users, archive data, preserve audit trails, and ensure compliant migration.
❓ Frequently Asked Questions
What is model deprecation?
A formal announcement that a model is outdated or no longer supported, signaling the end of maintenance and updates.
What are sunset criteria in AI governance?
Predefined conditions that trigger retirement of a model, such as degraded performance, drift, regulatory changes, or high risk.
What are common steps in deprecation planning?
Assess performance and risk, notify stakeholders, define a sunset date, prepare a migration plan, archive data/artifacts, and safely decommission.
How should deprecation be communicated to users?
Provide a formal notice with the rationale, timeline, impact, and alternatives, plus guidance for migration and support.
What is the difference between deprecation and sunset?
Deprecation is the announcement that a model will no longer be supported; sunset criteria are the predefined rules that determine when retirement occurs.
