Alias release

An immutable, versioned snapshot of an alias’s resolution policy, so a routing decision can be reproduced exactly.

A live alias points at one alias release at a time. The release is frozen: changing a provider-model revision creates a new release rather than mutating the old one.

Customer logs expose the release id, so any past decision can be explained and replayed.

Model alias

A stable logical name like code.fast that resolves through an immutable release to a concrete provider model.

Replay

A controlled experiment that re-runs a captured workload shape against candidate execution profiles to compare cost, latency, and capture.

See it in practice.

Definitions are useful; measurement is better. Run a diagnostic on your own workload.
