Grok 4.5, our most intelligent model yet, is now on grok.com, X, iOS, and Android.
Grok 4.5 now powers Grok wherever you use it, live today on grok.com, on X, and in the Grok apps for iOS and Android.
Grok 4.5 is our most capable model yet. In everyday use, it follows what you're actually asking, keeps track of longer conversations, and gives clearer, more reliable answers. Ask it to explain something unfamiliar, weigh a big purchase, plan a trip, or dig into a topic you're curious about. And on harder questions, it reasons more efficiently, so the answer arrives sooner.
Grok 4.5 can also take a task from start to finish. It can build out a working spreadsheet, turn an outline into clean slides and diagrams, draft clear prose, and pull the key points from a long PDF, whether you're at your desk or on your phone.
Grok also works directly inside Word, Excel, PowerPoint, and Outlook with our Microsoft 365 add-ins. For more details on the model itself, read the Grok 4.5 announcement.
