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 productsThe provider has retired this model. It is not counted as usable.
  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.

Lifecycle ≠ availabilityThe provider retired this model on 14 Jul 2025. According to an older statement, GitHub Copilot still lists it; a retired model is not counted as usable anywhere.

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.
