Grok 4.5 Rolls Out to iOS, Android, Web, and X

xAI announced that Grok 4.5, the model it introduced earlier in July, is now available everywhere: grok.com, X (formerly Twitter), and dedicated iOS and Android apps. This brings xAI’s most capable model to mobile devices, not just desktop.

Details

• Improved conversation: Grok 4.5 “follows what you’re actually asking, keeps track of longer conversations, and gives clearer, more reliable answers”
• End-to-end complex tasks: Users 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
• Faster reasoning on hard questions: The model is designed to speed up reasoning on difficult problems
• Microsoft 365 integration: Grok is already integrated into Word, Excel, PowerPoint, and Outlook through dedicated add-ins

How to try it
