Canary Model - CI/CD Glossary Definition
A canary model receives a small slice of live traffic first so its metrics can be validated before a full rollout.
A canary model is a new model version rolled out to a small fraction of live traffic first, so its real-world metrics can be checked before a full rollout or rollback.
Canary rollout applies progressive-delivery safety to models: expose the new version to a few users, watch, then widen or roll back.
Watch then widen
A canary serves real users with a small traffic slice while monitoring compares its error rate and quality to the incumbent, then traffic widens only if metrics hold.
