The model, available the same day in Cursor, Grok Build and via the Grok API (identifier grok-4.7), remains at the same base price as Grok 4.6 (2 dollars per million input tokens, 6 dollars for output) and targets coding and knowledge work on long-running tasks. A Fast variant doubles output throughput at double the price. The API release notes confirm a context window of 500k tokens. ![Photo: Ilya Pavlov - Unsplash](https://images.unsplash.com/photo-1461749280684-dccba630e2f6?w=1600&q=80&auto=format&fit=crop) xAI put the **Introducing Grok 4.7 post** online at x.ai/news on **Monday, September 21, 2026**, accompanied by an update to the API release notes for the identifier **`grok-4.7`**. The announcement was published in the late afternoon, around **6:31 PM** (Europe/Brussels) — as recently as the previous evening, nothing suggested this launch was coming. According to the post, **Grok 4.7** is presented as the company's most capable model for **coding** and **knowledge work**. It is said to hold up longer on difficult tasks, verify its own work more thoroughly, and come with a new stack of safeguards. It is offered **at the same base price and speed** as **Grok 4.6**, with a **Fast** variant offering **twice** the output throughput for **twice** the price. The text describes a **broader base** than Grok 4.6, longer **reinforcement learning** training on a mix of harder tasks, weighted toward problems that take **several hours**, better handling of long context, as well as native training on the **Grok Bot** harness. ## Availability and pricing, starting today The model is available **the same day** in **Cursor** and **Grok Build**, via the **Grok API**, third-party coding harnesses, model routers, and cloud platforms. The starting price cited in the post is **2 dollars** per million input tokens and **6 dollars** per million output tokens. The API release notes specify the product details: model **`grok-4.7`**, **500k** context, text and image input, text output, with four reasoning effort levels — low, medium, high (default) and **xhigh**. On the API pricing side: **2 / 0.50 / 6** dollars per million (input / cache / output) under 200k prompt tokens, then **4 / 1 / 12** beyond that. **Grok 4.7 Fast** is reserved for Cursor and Grok Build; it is **not** available on the public xAI API. ## What the in-house benchmarks show The official table compares Grok 4.7 (xHigh), Grok 4.6 (High), GPT-5.6 Sol Max and Fable 5.1 Max. On **CursorBench 4.0**, Grok 4.7 reaches **46.3%**, ahead of Grok 4.6 (**40.4%**) and GPT-5.6 Sol Max (**41.7%**), but behind Fable 5.1 Max (**51.8%**). On **DeepSWE v1.1** at high effort, it posts **71.0%**. On **Terminal-Bench 4.0**, the jump over Grok 4.6 is clear: **38.0%** versus **20.3%**. On **EEBench**, the score is **64.0%**. On multi-hour office tasks (**AA Briefcase v1.1**) and clinical reasoning (**HealthBench Professional**), the post presents Grok 4.7 as a clear improvement over 4.6, within the pack of frontier models. These scores remain those from the announcement and will need to be cross-checked with independent evaluations once the model is widely accessible outside xAI channels. ## Safeguards, cyber and biosecurity xAI claims a new safeguards stack, better refusals and increased resistance to jailbreaks. On its **HackerBench v0.3** benchmark, the post claims that only **3.3%** of risky dual-use prompts get through, while limiting false blocks on legitimate security work. An **invite-only** access to red-team capabilities is open to selected cybersecurity partners. On the **LatchBio** biosecurity benchmark, the text claims **62.4%**. These claims remain vendor claims: they do not replace a public third-party audit of production behavior. The next step will be operational: API latency and stability outside of demos, real-world performance on CursorBench or SWE beyond in-house scores, and how cyber safeguards behave as traffic scales up. ## Sources - [Introducing Grok 4.7 — SpaceXAI / x.ai](https://x.ai/news/grok-4-7), September 21, 2026 - [Release notes — docs.x.ai (Grok 4.7 / `grok-4.7` entry)](https://docs.x.ai/developers/release-notes), September 2026 - [News index — x.ai/news](https://x.ai/news), entry dated September 21, 2026 ## Frequently asked questions ### What is Grok 4.7 It is the new frontier model announced by SpaceXAI on **September 21, 2026**, geared toward coding and knowledge work on long-running tasks, with a safeguards stack presented as renewed. ### Is Grok 4.7 available today Yes, according to the announcement, via **Cursor**, **Grok Build**, the Grok API (`grok-4.7`), third-party harnesses, and cloud platforms. The **Fast** variant remains limited to Cursor and Grok Build. ### What is the price of Grok 4.7 The post cites **$2** per MTok for input and **$6** per MTok for output for the base version, at the same level as Grok 4.6. The API release notes also detail the cache price and the doubling of prices beyond 200k prompt tokens. The Fast version doubles both throughput and price. ### How does Grok 4.7 differ from Grok 4.6 According to xAI: a broader base, longer RL on multi-hour tasks, better self-verification and improved context handling, native training on Grok Bot, and new safeguards. The official tables show gains on several benchmarks, notably on Terminal-Bench and CursorBench versus 4.6.
