What backs this up?

Three kinds of evidence, kept apart. None of them proves AGI on its own; where one is missing, the page says so.

  1. In real productsRecorded, not checked: GitHub Copilot
  2. agi.jetzt PrüfstandNo published run yet.
  3. Public benchmarksNot recorded for this model yet.

A model and the product around it are different things: a result for one does not carry over to the other.

Announced and scoped lifecycle notices

These notices apply only to the named surfaces or API IDs. They do not replace current availability; an earliest possible date is not a confirmed shutdown date.

  • o3 · API · · · Deprecation · 11 Jun 2026 · o3-2025-04-16 · Source · checked on 11 Oct 2026
  • o3 · API · · · Removal / shutdown · 11 Dec 2026 · o3-2025-04-16 · Source · checked on 11 Oct 2026

Where can it be used?

Only recorded availability statements are shown. A missing plan or surface means unknown, not unavailable. Where it applies only to a plan or a region, the row says so. “Rolling out” is not “available”. “Rollout reported” means a rollout was reported, but nothing has supported it for more than 90 days.

Where a start is “not documented”, a source check found the state in place; the source names no start date.

What did we test?

No lab run of o3 is published yet.

Nothing is shown until a real run exists. See what the lab tests:

Lifecycle and history

The dates the provider confirmed, and every recorded period of availability. A current period shows its checked status; one without a source check is marked not verified.
