Anthropic key dates

Every Anthropic model we track with a published retirement date, soonest first. A model ID is a dependency with an expiry date, not a stable configuration value, and each row links to the vendor deprecation page it came from. For day-to-day announcements, see the Anthropic release feed.

Want these dates as email or Slack alerts at 90, 30 and 7 days out? Set up an EOL alert with the eol tag.
