xAI 发布 Grok 4.7，主打编码与知识工作
Grok 4.7 Sep 21, 2026 Introducing Grok 4.7 SpaceXSI's most powerful model for coding and knowledge work. Twice as fast, at half the price of comparable models. Read More
- 1xAI 发布 Grok 4.7，定位最强编码与知识工作模型，已在 Cursor 和 Grok Build 上线
- 2官方称价格与速度和 Grok 4.6 持平，每百万 token 定价输入 $2、输出 $6，另有快速版本
- 3官方基准显示 CursorBench 4.0 得 46.3%，低于 Fable 5.1 Max 的 51.8%
- 4官方称 LatchBio 生物安全基准得 62.4%，HackerBench v0.3 放行率仅 3.3%
xAI 以约同级一半的价格把 Grok 4.7 推向编码与知识工作市场，官方数据显示卖点在价格性能比和部分专业领域，并非全面领先。
- 影响：每百万 token 输入 $2、输出 $6 的单价低于官方对比表中的 GPT-5.6 Sol 与 Fable 5.1，编码类用量成本可重算；电气工程与法律基准官方数据领先，可进入选型对比清单；安全放行率数据对安全敏感业务有参考价值。
- 参考：可考虑先在 Grok Build 免费试用或 Cursor 中用自家真实编码与知识任务做对比，再按官方单价重算月度 token 预算；安全敏感团队可对照 HackerBench 与生物安全基准数据评估接入风险。
- 依据：各项基准与价格均为 xAI 官方口径，暂无独立验证，对比对象为 Grok 4.6、GPT-5.6 Sol 与 Fable 5.1。
Grok 4.7 is our most capable model for coding and knowledge work. It works longer on difficult tasks, checks its own work more carefully, and comes with our best-calibrated safeguards to date. Served at the same price and speed as Grok 4.6, it is highly competitive in its class.
On CursorBench 4.0, which stresses longer-running coding tasks, Grok 4.7 is at the frontier in price-performance.
Model Improvements
Grok 4.7 uses a new, larger base model compared to Grok 4.6. It was trained with a longer reinforcement learning run on a harder mix of tasks, weighted toward problems that take many hours to complete. The model is better at verifying its own work and managing longer context. We also trained Grok 4.7 to natively understand the Grok Bot harness, making it better at conversational tasks and general knowledge work.

Grok 4.7 is better at creating documents and presentations. In GDPval and AA Briefcase, AI is asked to work on tasks done by professionals such as lawyers, nurses, and financial analysts. Grok 4.7 improves upon Grok 4.6 on both benchmarks and performs comparably to other frontier models.

Safety & Cybersecurity
Grok 4.7 was built with an entirely new safeguard stack. It is the strongest model we’ve tested on refusals and jailbreak resistance. In dual-use domains like cybersecurity and biological work, it leads on both utility for benign tasks and safe refusal on dangerous ones, topping LatchBio’s biosafety benchmark at 62.4%.
Grok 4.7 balances strong cyber defense capabilities with low refusal rates for legitimate use. It shows the highest safety on HackerBench v0.3, our benchmark for risky and malicious cyber tasks, allowing only 3.3% of risky dual-use prompts through while rarely blocking legitimate security work. We’ve also started giving select cybersecurity partners invite-only access to Grok 4.7’s red-team capabilities for defense research.
Pricing and availability
Grok 4.7 is available today in Cursor and Grok Build. It is also available through the Grok API, third-party coding harnesses, and model routers and cloud platforms.
The model is priced starting at $2 per million input tokens and $6 per million output tokens. We also serve a fast variant with twice the output speed at twice the price.
