# Claude Model Lifecycle Monitor - Retirement Notices — workflow

## Choose this tool

AI application owners maintaining migration inventories for Claude models. Preserve exact retirement wording and official replacement recommendations.

Useful output columns: `modelId`, `currentState`, `deprecatedDateText`, `retirementDateText`, `recommendedReplacement`.

## Practical workflow

Enter the Claude model-family filters used in your application. Keep exact source retirement wording with your inventory, establish a baseline, and review later changes. Use official replacement guidance as a starting point for application testing, not an automatic migration.

## Check the fit

Official Claude model-deprecation table only. Filters match model IDs; ALL includes every current table row. Tentative dates and "not sooner than" wording remain literal, not converted into confirmed shutdown dates. Replacement guidance may be absent and does not prove application compatibility.

## Real output sample

One selected row from a 2026-10-18 run. One saved row with selected scalar fields. Nested structures remain available in full Actor output.

Run: LzoNefLNrbrNhNmSu. Summary status: ok. Incomplete: false.

Historical bounded output from the recorded run. Current source values may differ.
