AI Model Families: Pin Models, Watch Deprecations, and Plan Migrations
Frontier providers deprecate and silently update models; pin versions, monitor announcements, and run pre-migration evals so an upgrade does not become an outage.
Creators · Model Families · ~5 min read
The premise
A model the provider considers a minor update can change behavior on your tasks materially; pinning versions and running evals on every announced update is the only way to control the change.
What AI does well here
- Pin to specific versioned model IDs
- Subscribe to deprecation announcements per provider
- Run regression evals on every announced version
- Plan migration windows before the EOL date
What AI cannot do
- Stop providers from deprecating
- Predict surprise behavior changes between versions
- Replace a real eval before the cutover
