Claude API model deprecations

Rows come from the deprecation-history tables on Anthropic’s model deprecations page. The announced date is the date in the section heading, which is the date Anthropic says it notified developers. The replacement is the recommended replacement in that table. claude-mythos-preview is on the status table as Deprecated, with a Deprecated column of June 9, 2026 and a tentative retirement of “To be announced”. It has no history-table replacement, so the replacement cell is empty.

The page says publicly released models get at least 60 days’ notice before retirement. Dates apply to Anthropic-operated platforms: the Claude API, Claude Platform on AWS, and Microsoft Foundry. Amazon Bedrock and Google Cloud set their own retirement schedules. Active models with only a “not sooner than” date are not listed here, because that column is not a shutdown date.

21 rows. Filter matches the text already in the table.
