What Is Grok?Grok 是什么？
Grok is the flagship large language model family from xAI — which has since been renamed SpaceXAI. Known for real-time knowledge (deep integration with the X platform) and a more irreverent tone than its rivals, Grok is available as a chat assistant (web, iOS, Android) and as a developer API.Grok 是 xAI（已更名 SpaceXAI）的旗舰大模型家族。以实时知识（与 X 平台深度集成）和比竞品更不拘一格的语气著称，有聊天助手（网页、iOS、Android）和开发者 API 两种形态。
The current flagship is Grok 4.7, released September 21, 2026. Its predecessor Grok 4.6 (August 12, 2026) brought a 500K-token context window and developer-friendly API pricing: $2 input / $6 output per million tokens (verified 2026). In a $60 billion deal that closed August 14, 2026, Cursor was acquired — and Grok 4.6 is now integrated into all Cursor plans, so Cursor subscribers get Grok inside the editor with no separate API bill.当前旗舰是 Grok 4.7，2026 年 9 月 21 日发布。上代 Grok 4.6（2026-08-12）带来 50 万 token 上下文和对开发者友好的 API 定价：$2 输入/$6 输出每百万 token（2026 核实）。2026 年 8 月 14 日交割的 $600 亿收购让 Cursor 并入麾下——Grok 4.6 已集成进全部 Cursor 套餐，Cursor 订阅用户在编辑器里直接用 Grok，不用另付 API 账单。
What's next: Grok 5 is planned for release before the end of 2026. Until then, Grok 4.7 is the model to beat. Confirm current API pricing on the official site (x.ai).下一步：Grok 5 计划 2026 年底前发布。在此之前，Grok 4.7 就是旗舰。最新 API 价格以官网 x.ai 为准。
Grok's 2026 story is corporate before it's technical: the xAI → SpaceXAI rename and the $60B Cursor acquisition (closed August 14, 2026) fold the model into a much bigger machine. The product logic is clear — Grok 4.6 inside every Cursor plan makes the editor the default Grok distribution channel, and at $2/$6 per MTok the API undercuts several rivals on price per capability. Grok 4.7 (September 21, 2026) keeps the flagship fresh while Grok 5 brews for year-end. The honest tradeoffs: Grok's ecosystem (agents, tooling, third-party integrations) still trails Anthropic/OpenAI/Google, and the real-time X data advantage matters most for news-adjacent tasks. If you're already a Cursor subscriber, trying Grok 4.6 costs you nothing extra — that's the trial to run.
Grok 的 2026 年故事先是公司层面的、才是技术层面的：xAI 更名 SpaceXAI、$600 亿收购 Cursor（2026-08-14 交割），把模型装进了一台更大的机器。产品逻辑很清晰——Grok 4.6 进入全部 Cursor 套餐，让编辑器成为 Grok 的默认分发渠道；$2/$6 每百万 token 的 API 定价在同档能力里比好几家都便宜。Grok 4.7（2026-09-21）让旗舰保持新鲜，Grok 5 年底前接棒。真实短板：Grok 的生态（Agent、工具链、第三方集成）仍落后于 Anthropic/OpenAI/Google，X 实时数据的优势主要体现在新闻相关任务。如果你本来就是 Cursor 订阅用户，试用 Grok 4.6 不花一分钱——这个试用值得跑。
