Continuity policy
Dated snapshots are the norm and remain callable after the alias advances, which is the strongest routine protection in the category. Retirements are announced on a public deprecations page, but the notice window has historically been shorter than Anthropic's, closer to a quarter than half a year for API snapshots, and preview models have been pulled faster still.
