OpenAI deprecations tracker

Keep live migration briefs and dated shutdown risks in one view.

This page collects the OpenAI lifecycle items that already carry a shutdown date or migration burden. Use it as the index for live briefs and as the shortest path back to official OpenAI evidence.

Current state

The OpenAI deprecation cluster is now readable as a tracked set, not just isolated warning cards.
Live
Each currently tracked OpenAI shutdown item in this cluster now has its own decision brief, while the tracked-risk slot stays ready for the next dated lifecycle item.

Live briefs

These are the OpenAI shutdown paths that already justify their own decision brief.

Open the brief when the migration has enough object-model or interface change to need more than a single risk card.

DeprecatedAugust 26, 2026
Assistants API shutdown and migration path
OpenAI marks the Assistants API deprecated and directs new work toward the Responses API plus the Conversations API.

Replacement path

Responses API plus Conversations API

DeprecatedMay 7, 2026
Realtime API beta shutdown and GA migration brief
OpenAI marks the beta Realtime interface deprecated and routes teams to the GA Realtime API before the shutdown date.

Legacy GPT snapshots on a dated shutdown path
OpenAI places legacy GPT-4 snapshot IDs and older preview aliases on a March 26, 2026 shutdown path, with replacement guidance pointing to the gpt-5 or gpt-4.1 family.

Replacement path

gpt-5 or gpt-4.1 family

DeprecatedMay 7, 2026
gpt-4o preview audio and realtime model shutdown brief
OpenAI has also dated the shutdown of several gpt-4o preview realtime and audio models, with replacement paths now pointing to the current realtime and audio families.

Replacement path

gpt-realtime-1.5, gpt-realtime-mini, gpt-audio-1.5, or gpt-audio-mini

Tracked risk queue

All currently tracked OpenAI shutdown items now have a live brief.

This section stays empty until another dated OpenAI risk needs tracking before it earns a standalone brief.

No unbriefed OpenAI shutdown items are currently in this queue.

The current dated risks are already covered by live decision briefs. If OpenAI adds another smaller shutdown item, it will appear here before it needs its own page.

Current state

4 live briefs cover the current OpenAI lifecycle cluster.

Official sources

The cluster stays useful only if the source set stays narrow and auditable.

These pages are here to compress the decision surface, not to replace the docs. Every meaningful claim still needs a path back to OpenAI.

Return

Back to the main OpenAI decision surface
Use the deprecations index when lifecycle risk is the first question. Return to the main OpenAI tracker when you need to weigh that risk against pricing rows, hosted tool costs, and model constraints.
