LLM Model Deprecation Tracker
Every announced shutdown date across 3 providers, in one table, with a live countdown and the official replacement for each model. Calling a retired model does not silently fall back — it fails. This is the most common way a working LLM integration breaks in production, and the most avoidable.

Countdowns appear once the page loads in your browser, so they are always current rather than frozen at build time.
How each provider handles retirement
Anthropic
Publishes a "not sooner than" floor for every active model and commits to at least 60 days' notice before an actual retirement. Dates apply to the Claude API, Claude Platform on AWS and Microsoft Foundry; Amazon Bedrock and Google Cloud set their own schedules, so a model retired first-party may still run there.
OpenAI
Announces a deprecation date and a shutdown date roughly six months apart, and retires models in
large batches — eleven models share the 23 October 2026 date alone. Dated model IDs such as
gpt-5-2025-08-07 are retired independently of their undated aliases, so pinning an
exact snapshot buys reproducibility at the cost of a fixed expiry.
Announces shutdowns through the Gemini API changelog. Preview models are retired aggressively once
a GA equivalent ships — several -preview IDs were discontinued within weeks of their
stable counterparts becoming available.
Frequently asked questions
How much notice do LLM providers give before retiring a model?
Anthropic commits to at least 60 days of notice before retiring a publicly released model, and publishes a "not sooner than" date for every active model well in advance. OpenAI has typically given about six months between deprecation announcement and shutdown — for example, models deprecated on 22 April 2026 shut down on 23 October 2026. Google announces shutdown dates in its Gemini API changelog, often with shorter lead times for preview models.
What happens if I keep calling a retired model?
The request fails. There is no silent fallback to a newer model, so an application that hardcodes a retired model ID breaks outright on the shutdown date. This is the single most common way LLM integrations break in production, and it is entirely preventable.
Which models are shutting down soonest?
The table above sorts by shutdown date with a live countdown. As of August 2026 the near-term cluster is: the Google Imagen 4.0 family (17 August 2026), OpenAI Sora 2 and the Videos API (24 September 2026), the legacy GPT-3.5 and completions models (28 September 2026), and a large OpenAI batch including GPT-4 Turbo, GPT-4.1 nano, o1, o3-mini and o4-mini (23 October 2026).
Why do Anthropic dates say "or later"?
Anthropic publishes a "not sooner than" floor rather than a fixed retirement date for active models. The model will not be retired before that date, and customers with active deployments get at least 60 days of notice when a real date is set. Treat these as the earliest possible date to plan against, not a scheduled shutdown.
Do deprecation dates differ between the first-party API and cloud platforms?
Yes. Anthropic states that its published dates apply to the Claude API, Claude Platform on AWS and Microsoft Foundry, while partner-operated platforms — Amazon Bedrock and Google Cloud Vertex AI — set their own retirement schedules. A model retired on the first-party API may remain available on Bedrock or Vertex. Claude Opus 4.1 is a current example.
How do I audit which deprecated models my application still uses?
Anthropic exposes a usage export in the Claude Console (Usage → Export) that breaks down calls by API key and model, which makes it straightforward to find stragglers. More generally, avoid hardcoding dated model IDs across a codebase: route model selection through a single configuration constant so a migration is a one-line change rather than a search-and-replace.
