How do you version model artifacts in production?

medium

Answer

$(1) Semantic versioning (v1.2.3): major = incompatible schema, minor = new feature, patch = bug fix.$
$(2) Store immutable artifacts in registry (S3 + metadata DB).$
$(3) Tag with (git-commit, data-version, training-run-id).$
$(4) Deployment references version, not 'latest'.$
$(5) Multiple versions can serve simultaneously (traffic split).$
$(6) Retention policy: keep last N + all promoted.$
$(7) Include model signature (input / output schema) for compatibility checks.$

Check yourself — multiple choice

Random
Semver (major/minor/patch) + immutable registry + tag (git+data+run) + deploy references version not latest + multi-version serve + retention + model signature for compat
Not needed
Just latest

Model versioning: semver + immutable + lineage tags + no 'latest' in prod.
