## Route view, not a provider’s own schedule

Azure AI Foundry is a hosting platform, not a model provider. Every row below is a retirement date Azure AI Foundry has published for a model it hosts, sourced from Azure AI Foundry’s own retirement schedule — not each model provider’s first-party page. A hosted provider’s own API can publish a different date for the same model; see the divergence section below where that gap is documented and dated.

## Notice policy

60+ day minimum. At least 60 days’ notice before a generally available model’s retirement, sent by email and through Azure Service Health to subscriptions with active deployments

Preview models get at least 30 days’ notice. Each GA model’s retirement date — 18 months out, or 12 months for models from Anthropic, DeepSeek, Fireworks, and Mistral AI — is set at launch and isn’t extendable, except for shortened-notice emergency security retirements.

Fireworks AI’s models on Azure AI Foundry’s Standard (pay-as-you-go) tier are a narrower exception: a stated 15-day notice period before retirement. 13 of this page’s rows are Fireworks AI-hosted models subject to that clause.

Microsoft publishes forward-looking retirement dates ahead of the notice window.

## When the same model retires on different dates

The same model can carry a different published retirement date on each route it ships on. Radar does not reconcile the dates — use the one for the route you actually call.

## FAQ

### Which models is Azure AI Foundry retiring?

As of Oct 17, 2026, Azure AI Foundry has 111 upcoming dated retirements and 49 past for models it hosts. The next is claude-haiku-4-5 (Anthropic) on Oct 19, 2026. The soonest dated rows: claude-haiku-4-5 (Anthropic) on Oct 19, 2026; claude-opus-4-5 (Anthropic) on Oct 19, 2026; claude-sonnet-4-5 (Anthropic) on Oct 19, 2026. Every row in the tables above carries its own source receipt.

### When is the next Azure AI Foundry model retirement?

claude-haiku-4-5 (Anthropic) on Oct 19, 2026, as published in the source linked on that row. Dates marked "no sooner than" are floors, not deadlines.

### How much notice does Azure AI Foundry give before retiring a model?

Microsoft states at least 60 days’ notice before retirement: “At least 60 days’ notice before a generally available model’s retirement, sent by email and through Azure Service Health to subscriptions with active deployments.” Preview models get at least 30 days’ notice. Each GA model’s retirement date — 18 months out, or 12 months for models from Anthropic, DeepSeek, Fireworks, and Mistral AI — is set at launch and isn’t extendable, except for shortened-notice emergency security retirements. Fireworks AI’s models on Azure AI Foundry’s Standard (pay-as-you-go) tier are a narrower exception: a stated 15-day notice period before retirement.

### What does a "no sooner than" date mean?

It’s a floor, not a deadline. Some providers publish only the earliest possible shutdown date for a model, with the final date to be confirmed later. Treat it as "this won’t happen before this date," not as the date itself.

### What’s the difference between "Announced" and "First observed by Radar"?

"Announced" is the date the provider itself published the notice — it only appears on a row when the provider discloses one. "First observed by Radar" is Radar’s own collection timestamp, the date its pipeline first saw the source; it is never presented as the provider’s own announcement date.

### Is this Azure AI Foundry’s own retirement schedule?

No — Azure AI Foundry is a hosting platform for models from multiple providers, not a model provider itself. This page lists every retirement date Azure AI Foundry has published for a model it hosts, sourced from Azure AI Foundry’s own schedule. A hosted provider’s first-party API can publish a different date for the same model; the divergence section above lists the cases where that gap is documented and dated.
