Grok Updates: xAI Tracker, Timeline and Statistics

Two short posts on x.ai put Grok 4.6 into other companies' developer products. Both came within a week of it becoming the flagship.

On 14th Aug it went live in GitHub Copilot. It is selectable from the model picker across the cloud agents, the Copilot CLI and the VS Code IDE.

xAI notes that "some businesses and enterprises will need to enable the model from Copilot settings". On 19th Aug it reached general availability on Amazon Bedrock for developers in supported AWS regions.

The commercial terms are the same on both routes and on xAI's own console. They are 2 dollars per million input tokens and 6 dollars per million output.

xAI restates the model's shape in the Bedrock post. It has a 500,000-token context window with four configurable reasoning efforts: low, medium, high and xhigh.

Neither is a search or citation change, and neither touches the absent publisher controls that define this beat.

What the pair records is the distribution pattern this hub has now logged four times. The earlier cases were Grok 4.5 in Copilot and the Microsoft 365 and Google Workspace add-ins.

xAI ships its models into surfaces other companies already own faster than it builds its own.

So the places a Grok model can answer a question keep multiplying. None of them appears in xAI's own product list.

xAI positions Grok 4.6 as a step up from 4.5 on long-running agent work and on "more ambitious interactive and visual work". It claims stronger first-pass results on visual and interactive coding and more self-checking behaviour across long agent runs.

xAI says it matches OpenAI's GPT-5.6 Sol on the Artificial Analysis Intelligence Index. That index is a composite of nine benchmarks, and the score is 61 to 62.

That is xAI citing a third-party index rather than an independent evaluation of its own claim.

It launched live in Cursor and Grok Build, with double the included usage in both for the first week.

This is the model to name when anyone asks what powers Grok today. The cadence behind it is the real story.

Grok 4.5 reached every surface three weeks earlier, and 4.6 replaced it as flagship.

Grok Bot is xAI's standing-agent product. The bots run on their own cloud computer and sign into a user's existing tools, apps and websites "including ones with no API or MCP".

They work continuously rather than per task, and message back like a colleague when something needs approval.

It is in beta for SuperGrok Heavy, Cursor Ultra and Cursor Teams Premium subscribers on desktop and iOS. Enterprise customers get a waitlist.

Update: the waitlist ended on 3rd Sep, when Grok Bot opened to enterprises.

The phrase to notice is "including ones with no API or MCP". That describes an agent logging into a website through its ordinary front door, the same way a person would.

It is the pattern already visible in Gemini Spark's auto browse.

If you run a site with accounts behind it, this is a class of visitor to plan for. It fills forms, never sees your design and either completes a flow or fails silently.

It is a distinct product from Grok Build, the terminal coding agent, and from Automations, which runs scheduled jobs.

Build Mode builds a working website, app, game or interactive dashboard live inside the chat. The result is publishable to a "grok.me" link or a custom domain.

It is in early beta for SuperGrok Heavy subscribers on grok.com, iOS and Android.

At the time xAI treated it as a separate product from Grok Build, the terminal coding agent. Build Mode was the consumer version, no install and no code.

The two names were merged into "Grok Build" in August 2026.

The same day, Grok 4.5 became selectable in GitHub Copilot across VS Code, the Copilot CLI and cloud agents. Some enterprise accounts need it enabled by an admin.

xAI priced direct API access at 2 dollars per million input tokens and 6 dollars per million output.

This matters for anyone tracking where AI-generated sites come from. A one-prompt publish flow with hosted grok.me URLs is a new source of pages on the web.

It is not a source anyone can crawl-control.

The Google Workspace add-on covers three apps in one install from the Workspace Marketplace. In Sheets it answers questions from the data with cell citations and can write formulas and insert charts.

In Slides it turns an outline into a deck using web and X research plus images. In Docs it turns notes into structured drafts and can pull from Gmail and Drive through connectors.

It completes a run of add-ins shipped across four days in July. Excel came on the 20th and Outlook on the 21st, with Word earlier in June.

All are free through the Microsoft Marketplace to paid X and SuperGrok users.

The distribution pattern is the point. Rather than pulling people to grok.com, xAI is putting Grok inside the documents and inboxes where work already happens.

It is the same approach Google takes with Gemini in Workspace and Microsoft takes with Copilot.

Grok 4.5 went everywhere: grok.com, X, iOS and Android. It is framed for everyday questions and for "knowledge work", meaning spreadsheets, slide decks, drafting and summarising PDFs.

The post points to the Microsoft 365 add-ins for doing that work in place.

One thing this page cannot pin down, and says so rather than guessing: Grok 4.5's original launch date.

xAI's own news index places the "Introducing Grok 4.5" post between its 20th Jul and 16th Jul entries. That post returned a server error on every fetch attempt.

TechCrunch and Engadget both date the launch to 8th and 9th Jul, more than a week earlier. We confirmed their publication timestamps from the pages themselves.

We date this entry to the rollout post we could read. The discrepancy is unresolved, and it matters if you are citing a Grok 4.5 launch date anywhere.

SpaceX filed its IPO registration publicly on 20th May 2026. Three months earlier, xAI had become a SpaceX segment.

So the filing carried the first SEC-audited user figures for X and Grok since Twitter went private in October 2022.

Grok: 117 million monthly active users of Grok's AI features, for the twelve months ended 31st Mar 2026. X: 550 million monthly active users.

The filing also disclosed the xAI segment at 3.2 billion dollars of FY2025 revenue. Its operating loss was about 6.4 billion.

Read the segment figures carefully. The "xAI segment" bundles X's advertising and subscription revenue together with xAI's AI business.

So it is not an xAI-only number, and it should not be quoted as one.

There is also a figure that does not reconcile, and we print both rather than choosing.

xAI's own Series E post in January claimed about 600 million monthly active users "across the X and Grok apps".

That exceeds the later audited 550 million for X alone, and it covers a different period. It is a company statement, not an audited disclosure.

Google's documentation for GA4 default channel groups says "AI Assistants is the channel by which users arrive at your site from sources like ChatGPT, Gemini, Deepseek, Copilot, or Grok", and that the channel "excludes Google's AI Overviews and AI Mode". When GA4 recognises the referrer it assigns the medium "ai-assistant" automatically, with nothing to set up.

The exact timing matters. Search Engine Journal's coverage of the launch named only ChatGPT, Gemini and Claude as examples.

It noted that Google's help page had not yet been filled in. The page as it reads today does name Grok.

We date this to the coverage we can verify and note that Google's list was completed later.

This matters because it sits directly against the other measurement fact on this page. Statcounter, which runs the largest public cross-site referral panel, excludes Grok entirely on the grounds that it "does not provide referral data in its header".

Both can hold at once, and the accurate reading is narrow. GA4 will bucket a Grok visit that does arrive with a usable referrer.

Statcounter is describing a consistency problem across its whole panel.

No study we could find quantifies what share of Grok-driven visits carry a referrer at all. So check the channel in your own GA4 rather than assuming a number.

The deal was announced around 2nd Feb 2026, and it valued the combined company at about 1.25 trillion dollars.

SpaceX was put at roughly 1 trillion and xAI at roughly 250 billion standalone.

It was the third structural change in under a year.

xAI and X Corp merged in an all-stock deal announced 28th Mar 2025. The company then closed a 20 billion dollar Series E in January 2026, and SpaceX absorbed the result.

Two practical consequences for anyone reading Grok coverage. The company's own site now brands itself SpaceXAI, which is not a typo when you see it.

And because xAI became a reportable SpaceX segment, its numbers landed in an SEC filing. That is how the 117 million user figure became public at all.

The European Commission opened formal proceedings under the Digital Services Act on 26th Jan 2026. They concern Grok's generation of sexualised imagery of real people without consent.

It came in the middle of a fast-moving month. Indonesia blocked Grok on 11th Jan, the first country to do so, and Malaysia and the Philippines followed.

Ofcom opened a formal investigation under the UK Online Safety Act on 12th Jan. That regime carries fines of up to 18 million pounds or 10 percent of global revenue.

Ireland's Data Protection Commission opened a GDPR inquiry on 17th Feb.

We cover this because it is availability and platform risk. That is on-beat for anyone deciding whether to build on Grok, or to count on its reach in a market.

We deliberately do not cover the individual criminal and civil cases behind it. They are unresolved, several dockets do not cleanly match across districts, and they are not a marketing story.

The underlying capability is not incidental to the product either. SpaceX's own IPO filing, per Forbes, names Grok's "Spicy" mode as a possible source of reputational harm.

That is an unusual thing for a company to tell prospective investors about its own feature.

xAI's Series E post put the round at 20 billion dollars, "exceeding the $15 billion targeted round size". It names Valor Equity Partners, Stepstone Group, Fidelity, the Qatar Investment Authority, MGX and Baron Capital Group.

Nvidia and Cisco Investments are named as strategic investors.

The same post claimed compute of "over one million H100 GPU equivalents" at its Colossus data centre. Note the unit.

GPU equivalents is a normalised measure, not a raw count of cards. So it cannot be compared directly with anyone else's raw GPU numbers.

This post also carries xAI's claim of about 600 million monthly active users across the X and Grok apps. The later audited filing does not support it.

Grokipedia launched on 27th Oct 2025 as an AI-generated encyclopedia, reaching more than 6 million articles.

Its search-visibility arc is the part that concerns anyone in this field. Clicks from Google rose steeply into January 2026, then fell sharply from February onward.

The source is SISTRIX analysis carried by Search Engine Roundtable. Separately, PPC Land reported in August 2026 that its edit pipeline appears to have been frozen since 24th Apr 2026.

It is also now a citation source for other AI systems. Both ChatGPT and Claude have been observed citing Grokipedia on some queries.

That makes its content quality a cross-system problem rather than an xAI-only one. An academic analysis found it citing white-nationalist and conspiracy sources at meaningful scale.

There is nothing here a site owner can act on directly, since Grokipedia is xAI's own property. It is on this page because readers ask about it.

It is also a live demonstration of how quickly an AI-generated corpus can gain and lose search visibility.
