What is Canary Release?

A deployment strategy that exposes a new version to a limited slice of traffic or infrastructure before expanding the rollout.

Why does Canary Release matter?

It limits the impact of defects and gives you production evidence before the new model, prompt, agent, or service reaches everyone.

Canary Release in practice

Route a small eligible cohort to the release, compare quality and operational metrics with the control, and stop or roll back on predefined failures.

What is the common confusion about Canary Release?

A canary release limits exposure; it does not replace pre-deployment tests, approval, or rollback preparation.
