Grok Updates: xAI Tracker, Timeline and Statistics

xAI's assistant, tracked from its own posts and filings: what it ships, how big it is, and the short honest answer on what site owners can and cannot control.

This page tracks Grok, the assistant xAI ships at grok.com, in the Grok apps, inside X, and through Grok Build, Build Mode and a growing set of Microsoft 365 and Google Workspace add-ins. It moves fast: xAI shipped four flagship models and three new agent products in the eight months to August 2026.

It is also the one assistant on this section with no publisher controls at all. There is no xAI crawler token, so nothing you can put in robots.txt will govern how Grok fetches your pages. The site-owner section sets out what is actually documented, including the parts that are documented absences.

One boundary worth naming: X's feed-ranking algorithm now runs on Grok's transformer architecture, but that is a social-platform story and it lives on our Social hub.

Model

Grok 4.6 becomes the flagship, aimed at long-running agents

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", with stronger first-pass results on visual and interactive coding and more self-checking behaviour across long agent runs.

On benchmarks, xAI says it matches OpenAI's GPT-5.6 Sol on the Artificial Analysis Intelligence Index, a composite of nine benchmarks, at a score of 61 to 62. That is xAI citing a third-party index rather than an independent evaluation of its own claim, which is worth keeping in mind.

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.

Product

Grok Bot: agents that sign into your tools and keep working

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

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, which 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 that 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.

Product

Build Mode ships, and Grok 4.5 arrives in GitHub Copilot

Build Mode builds a working website, app, game or interactive dashboard live inside the chat, 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.

It is deliberately not the same thing as Grok Build, the terminal coding agent. Build Mode is the consumer version: no install, no code.

The same day, Grok 4.5 became selectable in GitHub Copilot across VS Code, the Copilot CLI and cloud agents, with some enterprise accounts needing it enabled by an admin. xAI priced direct API access at 2 dollars per million input tokens and 6 dollars per million output.

Worth noting 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, and it is not a source anyone can crawl-control.

Product

Grok lands inside Google Workspace, completing the Office set

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 on the 20th, Outlook on the 21st, and Word earlier in June, all 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, which is the same play Google runs with Gemini in Workspace and Microsoft runs with Copilot.

Model

Grok 4.5 reaches grok.com, X, iOS and Android

Grok 4.5 went everywhere: grok.com, X, iOS and Android, framed for everyday questions and for "knowledge work", meaning spreadsheets, slide decks, drafting and summarising PDFs, with a pointer 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 July and 16th July entries, and that post returned a server error on every fetch attempt. TechCrunch and Engadget both date the launch to 8th and 9th July, more than a week earlier, with publication timestamps we confirmed from the pages themselves.

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

DataSpaceX's IPO filing produces the first audited Grok user number: 117 million

SpaceX filed its IPO registration publicly on 20th May 2026, and because xAI had become a SpaceX segment three months earlier, 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 March 2026. X: 550 million monthly active users. The filing also disclosed the xAI segment at 3.2 billion dollars of FY2025 revenue against an operating loss of 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 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.

DataGoogle Analytics starts counting Grok referrals for you

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 timing is worth stating precisely. Search Engine Journal's coverage of the launch named only ChatGPT, Gemini and Claude as examples and noted 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 honest reading is narrow: GA4 will bucket a Grok visit that does arrive with a usable referrer, while 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.

LegalSpaceX absorbs xAI, and the site starts calling itself SpaceXAI

The deal, announced around 2nd February 2026, valued the combined company at about 1.25 trillion dollars, with SpaceX 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 March 2025. xAI then closed a 20 billion dollar Series E in January 2026. Then 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, which is how the 117 million user figure became public at all.

LegalThe European Commission opens a DSA investigation over Grok

The European Commission opened formal proceedings under the Digital Services Act on 26th January 2026, concerning 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 January, becoming 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 January, a regime carrying fines of up to 18 million pounds or 10 percent of global revenue. Ireland's Data Protection Commission opened a GDPR inquiry on 17th February.

We cover this because it is availability and platform risk, which is on-beat for anyone deciding whether to build on Grok or count on its reach in a given 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, which is an unusual thing for a company to tell prospective investors about its own feature.

DataxAI closes a 20 billion dollar Series E with Nvidia and Cisco investing

xAI's Series E post put the round at 20 billion dollars, "exceeding the $15 billion targeted round size", naming Valor Equity Partners, Stepstone Group, Fidelity, the Qatar Investment Authority, MGX and Baron Capital Group, with Nvidia and Cisco Investments 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 is also the post carrying xAI's own claim of about 600 million monthly active users across the X and Grok apps, which the later audited filing does not support.

ProductGrokipedia launches, and briefly becomes a search-visibility story

Grokipedia launched on 27th October 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, per 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 April 2026.

It is also now a citation source for other AI systems: both ChatGPT and Claude have been observed citing Grokipedia on some queries, which 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 earns its place because readers ask about it, and because it is a live demonstration of how quickly an AI-generated corpus can gain and lose search visibility.

Data

Tow Center: Grok cited news worse than any other AI search tool tested

The Tow Center study, by Klaudia Jazwinska and Aisvarya Chandrasekar, fed each of eight AI search tools a direct excerpt from a news article and asked it to identify the headline, publisher, date and URL. Two hundred queries per tool, 1,600 in total.

Grok-3 Search failed on 94% of queries, the worst of the eight. Of its 200 citations, 154 led to error or 404 pages. Grok-2 tended to link to publisher homepages rather than the specific article. Perplexity had the lowest failure rate at 37%.

Date this one carefully whenever you cite it. It tested Grok-2 and Grok-3 in March 2025, and Grok is on the 4.x line now. We could find no equivalent public retest of current models using the same methodology, so it is evidence about Grok then, not proof about Grok today.

It still matters, because it is the only independent measurement of Grok citation ACCURACY that exists, and because xAI does document a real citation system, as the next section sets out. Citing and citing correctly are different things.

Grok and your site: what you can control, and what you cannot

The short answer is that you cannot control Grok through robots.txt, because there is nothing to address. Here is what is actually documented.

NoneCrawler user-agent tokens published by xAI

There is no crawler token, and that is a documented absence

Every other assistant on this section gives publishers something to address in robots.txt. OpenAI has GPTBot and its siblings, Anthropic has ClaudeBot, Perplexity has PerplexityBot, and Google has Google-Extended. xAI publishes nothing equivalent.

We checked directly. x.ai/robots.txt, grok.com/robots.txt and grokipedia.com/robots.txt contain no xAI, Grok or GrokBot token. Cloudflare's AI Crawl Control bot reference, which lists documented crawlers by operator for a dozen companies, has no xAI entry.

One thing that looks like a control and is not: x.ai's own robots.txt does contain groups for GPTBot, ClaudeBot, PerplexityBot, Google-Extended and Applebot-Extended, plus a Content-Signal line. That is xAI stating how it wants its OWN site treated by other companies' bots. It is not a lever you can pull.

Search Engine Journal's crawler reference lists Grok under a separate heading for agent crawlers with an unidentifiable user agent, noting "there is no way to track this crawler from accessing webpages other than by identifying the explicit IP". Search Engine Land's guide says some crawlers "don't identify themselves at all in user-agent strings" and names Grok, which "seems to mimic an iPhone, according to some tests".

Treat that last mechanism as thin. It is soft sourcing with no named study or methodology, and the more elaborate versions circulating in SEO coverage, rotating residential IPs and specific spoofed strings, have no primary source at all. The core negative is solid and the specific technique is not. If you want to restrict Grok, the honest answer today is that it has to happen at the server or WAF level rather than in robots.txt.

Grok does cite, and it is documented

xAI's developer documentation describes a real citation system with two formats: a full citations list of every source URL the model touched, and inline markdown links embedded in the response text as [[N]](url), numbered from one. Each carries structured metadata including the URL, a title, and character offsets marking exactly which span of text it supports.

Defaults differ by surface, which matters if you are testing what users see. Inline citations are on by default in the Responses API, and off by default in xAI's Python SDK unless explicitly requested.

Citing and citing correctly are different things, though, and the only independent accuracy study found Grok-3 failing 94% of citation tests, worst of eight tools. That study is from March 2025 and predates the current model line.

Measuring Grok traffic: one door open, one closed

Statcounter, which runs the largest public cross-site AI referral panel, excludes Grok outright. Its wording has been identical across releases a year apart, in June 2025 and again in May 2026: "Grok cannot be included in the data, as unlike the other chatbots, it does not provide referral data in its header." Every Statcounter AI referral chart you see, including the ones on our Gemini hub, therefore has no Grok line at all.

Your own analytics is the better route. GA4's AI Assistants channel names Grok among the referrers it recognises and buckets those sessions automatically under the medium "ai-assistant", with no setup.

The two facts do not cancel out, and neither gives you a number. GA4 catches Grok visits that arrive with a usable referrer. Statcounter is describing a consistency problem across an entire panel of sites. Nothing we could find quantifies what share of Grok-driven visits carry a referrer at all, so treat your own GA4 channel as the measurement and treat any published "Grok sends X% of AI traffic" figure with suspicion.

Grok plans and availability

Pricing from x.ai/pricing as read on . Two tiers exist in xAI's own comparison table with no price shown anywhere on the page, which is noted rather than filled in from older coverage.

Country availability is the volatile part. Indonesia blocked Grok on , the first country to do so, with Malaysia and the Philippines following. Anyone planning around Grok's reach in Southeast Asia should verify current status rather than trusting a list.

Grok statistics, and which ones can be compared

Grok's numbers are unusually messy because the company restructured three times in under a year, so figures arrive from a company blog, an SEC filing and app-analytics vendors, all measuring different things.

Two market-share figures that must never be quoted as agreeing. Apptopia, reported by Reuters, put Grok at 17.8% in January 2026. That is a three-way comparison whose figures sum to 100%, so Claude, Perplexity and everything else are excluded from the denominator entirely.

Sensor Tower separately put Grok under 5% of time spent across AI assistant apps through May 2026. Different metrics, different universes, so anyone presenting them as a trend is comparing two unrelated measurements.

One more figure to distrust: "35 million Grok monthly users, December 2025" circulates widely as the comparison baseline for the 117 million figure. We could not find it in the filing or in any fetched primary, only in secondary aggregators, so it is not on this page.

What Grok is, and where it ends

One assistant, several products, and one boundary that trips up most coverage.

Grok is xAI's assistant. You reach it at grok.com, in the Grok iOS and Android apps, inside X, and through add-ins for Word, Excel, PowerPoint, Outlook, Sheets, Slides and Docs.

Around the assistant sit several distinct products that coverage often merges. Grok Build is a terminal coding agent, now open-sourced, which can fan a task across up to 128 agents. Build Mode is the consumer version, building a site or app inside the chat and publishing it to a grok.me link. Grok Bot is the standing-agent product, signing into tools and working continuously. Imagine handles image and video generation. Grokipedia is a separate AI-generated encyclopedia.

The boundary that matters for this section: X's feed-ranking algorithm is now built on Grok's transformer architecture, and X open-sourced it in January 2026. That is genuinely interesting, and it is a social-platform ranking story rather than an assistant story, so we track it on the Social hub alongside Reddit, TikTok and the rest.

The company naming is its own small trap. xAI merged with X Corp in March 2025, raised a Series E in January 2026, and was absorbed by SpaceX in February 2026. Its site now brands as SpaceXAI, and its financial disclosures arrive inside SpaceX filings.
