Questions about this tracker

How often is this data updated?

Equibles checks platform.claude.com every day and has kept 3 captures since 2026-10-19.

Where does the data come from?

From platform.claude.com. Every value in the table is matched to the text on the source page before it is published.

About this tracker

Each row records one Claude API model identifier along with three lifecycle attributes pulled from the model documentation pages: the current state (active, deprecated or retired), the deprecation date if one has been set, and the tentative retirement date. Rows cover models currently active alongside already deprecated and retired ones, so the same table mixes entries still accepting traffic with entries that have already been shut down. A daily refresh keeps the deprecation and retirement fields aligned with the vendor's published lifecycle page.
