Frequently asked questions.

The details that keep a model change from becoming an outage.

What is an AI model retirement or shutdown?

It is the date a provider plans to stop serving a model through the covered API. After shutdown, requests using that model ID may fail until the application moves to a supported model.

Where do ModelSunset dates come from?

Every tracked date comes from official OpenAI, Anthropic, or Google documentation. Each record links to its provider source and shows the date it was last reviewed.

Does a deprecation notice always include a shutdown date?

No. A model can be deprecated, legacy, or scheduled for future retirement without a confirmed shutdown date. ModelSunset leaves the date blank until the provider publishes an explicit deadline.

Are the recommended replacements drop-in compatible?

Not necessarily. A replacement can differ in prompts, tool calling, structured output, context limits, latency, pricing, and availability. Test representative requests before changing production traffic.
