Grok 4.5 isn’t available in the EU yet, which is almost certainly why it’s not showing in your model list even after refreshing. This isn’t anything on your end. Due to notification requirements under the EU AI Act, it wasn’t initially available in the EU, and refreshing or updating won’t surface it until it’s enabled there.
We plan to make it available in the EU in the coming weeks. In the meantime, your other models (including Composer 2.5) are unaffected. You can follow the Grok 4.5 discussion thread for updates
