After saying at the model launch that they were still working on European access, less than a week later, OpenAI sends this tweet:
Pro users in the European Economic Area and Switzerland, thanks for your patience — ChatGPT agent is now fully rolled out to you.
And the rollout to Plus users globally has started and will continue over the next few days.
— OpenAI (@OpenAI) July 23, 2025
That clearly says the agent is coming to Pro Users in the «European Economic Area and Switzerland.»
It also says Plus users — globally — should have access over the next few days.
So if you happen to be in Europe, are a Pro or Plus subscriber, you should get access to the model shortly.
UPDATE 25/7/25: OpenAI reports that the rollout is complete. You can find it in the feature bar at the bottom of the app window by clicking on the “Agent” icon.
