AI Model Retirement Calendar

Every announced AI model shutdown date, in one table, with a linked source on every row. Proactive calm: know 60+ days ahead and already migrated.

OpenAI and Anthropic rows were hand-verified against the vendors' official deprecation pages on October 12, 2026. Google rows quote Google's deprecation page via published community audits (verification dates noted per row). When a date changes, the row changes — and every row tells you when we last checked.

How to read this calendar

• Upcoming — announced, still serving. This is your migration window.
• Watch list — the vendor's tentative floor ("not sooner than"), not an announced retirement. Included so you see it coming, never read it as a shutdown date.
• Retired — already shut down. Listed so you can spot a dead ID in old code before it confuses you.

OpenAI

Source: OpenAI API deprecations page · last verified 2026-10-12

Anthropic

Source: Anthropic model deprecations page · last verified 2026-10-12. Anthropic commits to at least 60 days' notice before retiring publicly released models. Dates apply to the Claude API, Claude Platform on AWS, and Microsoft Foundry — Bedrock and Google Cloud set their own schedules.

Google (Gemini)

Google publishes a Gemini API deprecations page but sets no notice-period policy — it tracks announced earliest shutdown dates. Rows below quote it via published community audits (per-row verification dates).

xAI

xAI publishes no model lifecycle index. Retirements appear only on per-event migration pages in the xAI developer docs (for example the May 15 retirement migration page), and the models API exposes no deprecation fields. We watch those pages and add xAI rows here when a date is announced — until then, the honest entry is: no announced retirements with a published date.

FAQ

Where do these dates come from?

Every row links to the vendor's own deprecation page — OpenAI's API deprecations page and Anthropic's model deprecations page — or to a published community audit that quotes Google's deprecation page. Each row carries a last-verified date. Verify against the official docs before you migrate: this calendar is a curated starting point, not the vendor of record.

What is the difference between deprecated and retired?

Deprecated means the model still works but is no longer recommended, with a replacement named and a retirement date assigned. Retired means requests fail — Anthropic states it directly: requests to retired models will fail — and OpenAI says at shutdown the model or endpoint will no longer be accessible.

What happens to my app on a model's shutdown date?

Requests that still name the retired model stop working — typically a 404 or model-not-found error. There is no automatic substitution and no warning header on the last 200 response. You migrate before the date, or you incident after it.

Why does xAI have no dates on this calendar?

xAI publishes no model lifecycle index. Its retirements appear only on per-event migration pages in its developer docs. We track those pages and add rows when xAI announces a date.

Can I put these dates in my own calendar?

Yes — download the shutdown calendar as .ics with 30/7/1-day reminders, or track the models you depend on with a free ModelMinder account and get alerted as dates approach.

Get the warning, not the incident

This page is the manual version of what ModelMinder does automatically: register the models your product depends on, and get alerted before the shutdown date — then prove the replacement works on your own prompts with a one-click migration eval before you switch traffic.
