xAI 将 Grok 4.5 带到 grok.com、X、iOS 和 Android 全平台
Bringing Grok 4.5 to iOS, Android, Web, and X Grok 4.5, our most intelligent model yet, is now on grok.com, X, iOS, and Android. Jul 22, 2026
- 1Grok 4.5 已上线 grok.com、X、iOS 和 Android，官方称迄今最强模型
- 2官方称其能跟上更长的对话、回答更清晰可靠，难题上推理更高效、出答案更快
- 3模型可端到端完成任务，包括做表格、把大纲转成幻灯片和图表、起草文稿、提取长 PDF 要点
- 4通过 Microsoft 365 插件，Grok 可直接在 Word、Excel、PowerPoint 和 Outlook 内使用
xAI 把 Grok 4.5 铺满网页、X 和移动端全入口，竞争重心从模型发布转向使用触达和办公场景渗透。
- 影响：员工在各端试用同一模型的门槛更低，AI 助手进入日常问答更顺；做表、幻灯片、读 PDF 这类任务型能力指向知识工作场景；Microsoft 365 插件为已用 Office 的企业提供接入现有工作流的路径。
- 参考：可考虑指定若干高频问答和文档任务，让员工在移动端与桌面端各试用一段并记录耗时与质量对比；已部署 Microsoft 365 的团队值得先评估插件的权限与数据边界，再小范围推开。
- 依据：能力描述与端到端任务表现均为 xAI 官方口径，暂无独立验证；上线范围和 Microsoft 365 插件细节以官方页面为准。
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.
Smarter answers to any question
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.
For all your knowledge work
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.
