AIREITERGrok 4.7 is being discussed as an upcoming xAI model, but I could not verify a public launch, API model ID, price, or benchmark card as of September 2, 2026. For developers, the practical approach is to treat 4.7 as unconfirmed and keep a documented Grok 4.6 integration ready.
The Grok 4.7 evidence ledger, checked September 2, 2026
A founder announcement can show that a model is being prepared; it does not establish a callable production endpoint.
| Item | What the sources show | Status |
|---|---|---|
| Official xAI launch page | The xAI news feed lists Grok 4.6 updates, but no Grok 4.7 launch entry appeared in the retrieved feed. | Not verified |
| Official API model ID | The xAI Models documentation lists grok-4.6; I found no grok-4.7 entry. | Not verified |
| Release date | Elon Musk publicly gave changing estimates, including “10 days” in a September 2 post. | Founder estimate, not a ship date |
| Model size | The 2.1T-parameter figure is attributed to Musk. | Unconfirmed specification |
| SpaceX data | Musk said supplemental training was adding a “massive amount” of SpaceX company data. | Attributed training claim |
| API pricing | No official Grok 4.7 price was published in the sources checked. | Unknown |
| Context window | No official Grok 4.7 context length was published. | Unknown |
| Benchmarks | No verifiable Grok 4.7 benchmark results were published. | Unknown |
No official launch, API, pricing, context-window, or benchmark documentation for Grok 4.7 was found.
Why the Grok 4.7 release date keeps moving
Grok 4.7’s schedule has been a set of estimates rather than a dated launch announcement. On August 12, Musk said initial training was complete, supplemental SpaceX data was being added, and the model was roughly three to four weeks away (Musk’s post).
On September 2, Musk later wrote that “Grok 4.7 comes out in 10 days” (post on X). That is a current public estimate, not confirmation that the API or consumer product will be live on a specific day.
One real-user Reddit comment captured the timing question without claiming hands-on access:
“Just out of curiosity, why not simply wait 4 weeks and release 4.7.” — u/ProposalOrganic1043, Reddit discussion
The available community material covers timing and expectations, not a reproducible Grok 4.7 test. There is therefore no evidence-based performance comparison to other frontier models yet.
What official xAI pages show—and what they do not
The official developer model page currently directs general text and code workloads to grok-4.6. It lists a 500,000-token context window, $2.00 per million input tokens, $6.00 per million output tokens, configurable reasoning, and a February 1, 2026 knowledge cutoff.
The same page separates the dedicated Voice API and Imagine API from the general-purpose text model. It also says real-time information requires Web Search or X Search tools. Those are current platform details, not evidence that Grok 4.7 has inherited the same limits or capabilities.
The Grok overview describes the broader product across web, iOS, Android, file uploads, voice, image and video creation, connectors, and SuperGrok plans. It does not document a Grok 4.7 model, price, or model-specific access rule.
Missing public documentation does not prove that xAI stopped training Grok 4.7. It does mean developers cannot plan against a verified interface or cost structure.
What “2.1T parameters” and “SpaceX data” do—and do not—tell you
A Kie explainer attributes the 2.1T figure to Musk’s statements and labels it unconfirmed. A parameter count does not establish performance, cost, latency, or whether the figure refers to total or active parameters in a particular architecture.
Musk’s August 12 statement identifies supplemental SpaceX company data, but does not publish the corpus, token count, or evaluation results. “SpaceX data” should not be expanded into assumptions about confidential telemetry, proprietary designs, or guaranteed aerospace expertise.
The official Grok 4.6 announcement shows why measured results matter. xAI reported a 61 score for Grok 4.6 on the Artificial Analysis Intelligence Index and supplied scores across coding and knowledge-work evaluations. Grok 4.7 has no comparable public table in the sources checked.
For now, 2.1T and SpaceX training are attributed claims about a planned model, not evidence that it is faster, cheaper, safer, or better at engineering.
Can you use Grok 4.7 today?
Not as a documented public API target based on the sources checked. The official model documentation names grok-4.6, and the official news feed shows continuing Grok 4.6 integrations rather than a Grok 4.7 launch entry.
| Access route | What counts as confirmed access |
|---|---|
| xAI API | A selectable grok-4.7 identifier in the official model list or console, plus API documentation. |
| grok.com or X | A visible model-picker entry that names Grok 4.7, not a social post or screenshot. |
| Cursor or another coding tool | The tool’s live model selector, supported-provider documentation, and billing terms. |
| A routing platform | A provider listing that maps to a real upstream model ID and states the price and limits. |
A third-party page can be an early signal, but it does not establish a stable production endpoint. The first dependable developer signal is a model ID that returns a successful request and has matching official pricing and limits.
The model developers can actually use now: Grok 4.6
Grok 4.6 is the documented fallback when a project cannot wait. xAI lists it for code, chat, and general-purpose workloads, with a 500,000-token context window and token pricing of $2 per million input tokens and $6 per million output tokens (official model documentation).
The official Grok 4.6 announcement says the model was available through the xAI API and several developer products. Its evaluation table includes an Artificial Analysis Intelligence Index score of 61.
Use Grok 4.6 as a testable baseline: record quality, cost, latency, tool-call success, and failures, then replay the same suite against 4.7 if it receives an official endpoint. For a consumer test, the Grok 4.6 chat page is the relevant current model entry.
A five-minute Grok 4.7 launch check for developers
Use this sequence before changing a production route:
- Check xAI’s official news feed. Look for a Grok 4.7 release note, not only a founder post.
- Check the official Models page. Confirm that
grok-4.7appears as a callable model and record the exact identifier. - Open the model-specific documentation. Record context length, modalities, reasoning settings, rate limits, batch support, and knowledge cutoff.
- Read the pricing page and model card. Do not infer 4.7 pricing from Grok 4.6’s $2/$6 rates.
- Run a non-sensitive pilot. Replay fixed coding, research, tool-use, and long-context tasks against Grok 4.6 before routing real traffic.
Keep the model ID as a configuration value rather than embedding it throughout the application. That lets you test 4.7 while retaining a fallback without changing business logic.
Grok 4.7 FAQ
Has Grok 4.7 been officially released?
I could not verify an official public launch in xAI’s retrieved news feed or developer model documentation as of September 2, 2026. Public statements indicate an upcoming model, but the documented model entry remains Grok 4.6 (xAI news, xAI Models).
When will Grok 4.7 be released?
Musk’s latest public estimate in the sources checked said “10 days,” after an earlier three-to-four-week estimate. Neither statement is a guaranteed API or consumer-app launch date (September 2 post).
Is Grok 4.7 really a 2.1-trillion-parameter model?
The 2.1T figure is attributed to Musk and repeated by third-party trackers, but I found no official xAI model card confirming it. Treat it as a reported claim until xAI documents the architecture and parameter definition.
Will Grok 4.7 be available through the xAI API?
That is a likely access route, but it was not documented in the official model list checked here. Wait for a real grok-4.7 identifier, pricing, and request documentation rather than relying on a pre-added SDK enum or screenshot.
How much will Grok 4.7 cost?
No official Grok 4.7 price was published in the reviewed sources. Grok 4.6’s $2 per million input tokens and $6 per million output tokens are a baseline, not a forecast for 4.7.
Should developers wait for Grok 4.7?
Wait if you are only comparing models and have no delivery deadline. If work needs to ship, use the documented Grok 4.6 baseline, keep the model selection reversible, and re-run the same evaluation set when 4.7 receives official documentation.
Next step: bookmark the official xAI Models page, keep grok-4.6 as the explicit fallback, and treat Grok 4.7 as ready only when the model ID, price, limits, and release documentation agree.
