We use the term “legacy” to refer to models and endpoints that no longer receive updates. We tag endpoints and models as legacy to signal to developers where we’re moving as a platform and that they should likely migrate to newer models or endpoints. You can expect that a legacy model or endpoint will be deprecated at some point in the future. Upcoming deprecations Upcoming deprecations are listed below, with the most recent announcements at the top.	We use the term “legacy” to refer to models and endpoints that no longer receive updates.
