Concern 94 · Working draft · editorial review in progress
Retraining cadence tradeoffs
Retraining-cadence tradeoffs are the choices about how often to update a model as data and conditions change.
Understanding the concern
Updating too slowly can leave an outdated model in place. Updating too quickly can introduce poorly checked changes, react to temporary noise, or make performance hard to compare across versions.
There is no single best schedule for every task. The decision should consider how quickly the setting changes, how serious mistakes would be, and how reliably a new version can be tested and reversed.
An example
A map service needs updates, but publishing every unverified road report immediately could create new wrong routes.
Illustrative unless identified as a documented case.
Words in plain English
- Model
- The learned part of an AI system. It uses patterns found during training to produce an answer or prediction.
Evidence and its limits
Supports maintenance and feedback considerations; no universal update frequency is prescribed.

Virtues and principles to consider
Virtues are qualities we practice in how we treat people and make choices. They are not scores for judging someone. Use these ideas to explore what a thoughtful response could look like.
Humility
Humility means recognizing the limits of our knowledge and being willing to learn from others. Expertise can be valuable without answering every question.
State where evidence is weak, invite criticism, and listen to people with different experience. Leave room to revise a decision when new information appears.
Ask together: What might we be missing, and who could help us see it?
Prudence
Prudence means using careful judgment before and during action. It balances worthwhile opportunities with the need to avoid harm that could have been anticipated.
Start with a limited trial, set stopping points, and prefer choices that can be undone when uncertainty is high. Review what happens rather than assuming the original plan remains sound.
Ask together: What is a careful next step, and when should we stop or change course?
Truthfulness
Truthfulness means making claims that match the evidence and being clear about what we do not know. It includes correcting mistakes rather than protecting a polished story.
Check sources, label guesses, and distinguish a trial result from a proven benefit. If AI helped produce a claim, someone still needs to take responsibility for checking it.
Ask together: What can we honestly say, and what still needs checking?
